Engine replacement cost in Australia has no single answer, because two quotes with the same headline price can cover very different things. One may be a bare engine with nothing attached, another a supply-and-fit package with fluids and testing. This guide separates the engine price from the fitting price and from the extras, then shows dated Australian price points for new, reconditioned and used engines, labour, rebuilds and engine swaps. Every figure carries its source and the date it was published or read, and undated pages are labelled. Where we could not find a dated Australian figure, we say so and do not guess. For the cost of a related job, see our timing belt replacement cost guide, and if you are weighing imported units, see our Japanese import engines guide.

Quick Answer: What Does an Engine Replacement Cost in Australia?

• Whole job: a Western Australian workshop (published 16 December 2025) puts a full engine replacement at about $3,096 to $11,097 and says the final figure depends on labour, make and model, engine type and parts availability. Treat it as a published range, not a survey.
• Engine only, new: a Ford parts dealer’s listing, read on 22 October 2026, shows a new genuine Ranger 3.2 diesel engine at $8,416.83, without injectors, injection pump, ancillaries or gaskets.
• Engine only, reconditioned: a reconditioned-engine seller’s Hilux listing, read on 22 October 2026, shows an engine at $6,390 including GST, plus an $850 core fee that is refunded when a usable engine is returned.
• Engine only, used: wrecker listings read on 22 October 2026 ranged from $3,450 (BT-50 3.0 diesel) to $6,250 (BT-50 3.2 diesel) for the utes we checked.
• Fitting: a Victorian reconditioning specialist (published 19 July 2026) gives $1,000 to $2,500 for fitting an engine you bought separately, depending on the vehicle.
• Extras: radiators, engine mounts and clutches are often not in the engine price, and freight, GST treatment and warranty terms vary by seller.
• Rules: a replacement engine usually carries a different engine number, and the states we checked (NSW, Victoria, Queensland and Western Australia) each have a process for updating it. Check your own state’s rules.

Engine Replacement Cost at a Glance

1. New or crate engine

• Price signal: $8,416.83 for a new genuine Ford Ranger PX 3.2 diesel engine (RRP shown as $10,100.20), read 22 October 2026
• Includes: the engine block assembly only. The listing says it does not include injectors, injection pump, ancillary items or gaskets
• Watch for: “new” can mean a new genuine factory engine, or a long engine built with a new block and head. Ask which

2. Reconditioned exchange engine

• Price signal: $6,390 including GST for a reconditioned Toyota Hilux diesel engine, plus an $850 refundable core fee, read 22 October 2026
• Includes: a bare long motor with no accessories or fuel system
• Watch for: the core rules, the warranty conditions and whether fitting is extra

3. Used engine

• Price signal: $3,450 to $6,250 for the BT-50, Triton and Navara D40 diesel engines we found, read 22 October 2026
• Includes: varies by listing. Some include the turbo, injectors and EGR. Others do not say
• Watch for: kilometres, tested or untested, warranty length and whether labour and freight are excluded

4. Rebuilding your existing engine

• Price signal: $3,500 to $5,500 for a four-cylinder rebuild including parts, machining and labour (a Victorian specialist, July 2026). A Sydney workshop (March 2025) said $2,500 to $4,500
• Includes: stripping, machining and reassembly with new bearings, rings, gaskets and seals
• Watch for: severe damage, diesels and turbo engines push the cost higher, and a rebuild takes longer than an exchange

5. Fitting and labour

• Price signal: $1,000 to $2,500 to fit an engine bought separately (Victorian specialist, July 2026)
• Hours: 8 to 15 hours for a used, remanufactured or reconditioned replacement and 10 to 20 or more for a new engine (Western Australian workshop, December 2025)
• Watch for: rates quoted from about $100 to about $200 an hour depending on the source, so ask for the hours and the rate separately

6. Extras that can appear

• Examples: injectors, injection pump, ancillaries, radiator, engine mounts, clutch, fluids, timing belt or chain parts, freight and GST
• Watch for: the same engine can look cheaper or dearer depending on what is left out

Engine Replacement Cost Breakdown

An engine replacement quote is several costs added together. The engine is the biggest line, and fitting is usually the second.

What can be in a quote

• The engine: new, reconditioned, rebuilt, remanufactured or used, with a condition and an engine code
• Fitting: removing the old engine, moving over parts, fitting the replacement and testing
• Parts that go with it: gaskets, fluids, belts or chains, mounts, the clutch and, on some engines, injectors
• Freight: a regional or interstate delivery can be extra. One wrecker listing we read said freight was not in the price and asked for a postcode to quote
• Tax: some listings state GST and many do not. The Hilux reconditioner’s price was stated as including GST, while the Ford parts dealer and most wrecker listings did not say
• Deposits or cores: an exchange engine can carry a core fee that is refunded when your old engine is returned

A worked example, not a quote

A used Mitsubishi Triton 2.4 diesel (4N15) was listed on 22 October 2026 at $4,950. Add the Victorian specialist’s general fitting range of $1,000 to $2,500 and the engine and fitting come to roughly $5,950 to $7,450. That adds two separately sourced numbers and leaves out freight, fluids, extra parts and any repairs found when the old engine comes out, so a real quote will differ. The fitting range came from a business that mostly works on Hyundai and Kia engines, and we found no verified fitting time for a diesel ute.

Why published totals disagree

The sources we read give different ranges for the same job. The Western Australian workshop’s full replacement range of $3,096 to $11,097 is wide. A Sydney workshop (March 2025) put a reconditioned engine at around $12,000 and a new engine at up to $28,000, well above the others. The gap is a reminder to compare the scope of each quote, not just the total.

Engine-Only Price Versus Fitted Cost

A price for “an engine” and a price for “an engine replacement” are not the same thing. Check which one you are reading.

Reading an engine-only price

• Bare or long motor: the Ford parts dealer’s listing and the Hilux reconditioner’s listing both sell the engine block assembly without accessories. The Hilux listing says it is sold as a bare long motor with no accessories or fuel system, and the Ford listing says it does not include injectors, injection pump or ancillary items and gaskets
• Complete engine package: one Navara D40 wrecker listing described a complete engine including the turbo, injectors and EGR, at 169,080 km and tested before dismantling. Another Navara listing was a long engine assembly with no inclusions listed
• Warranty on the bare unit: the wrecker listings we read give a 3 month parts warranty that covers the bare unit only and excludes labour and freight, and say it is void if the engine overheats or is installed incorrectly. A parts and labour warranty was offered on request

Reading a fitted price

• Supply-and-fit: the Victorian specialist says supply-and-fit packages include the engine, installation, fluids and testing in one quote
• Exchange: the same business says an exchange engine’s price covers the engine but not fitting
• Not assumed: do not assume a fitted quote is only labour. Ask what parts, fluids and testing it includes

New and Crate Engine Costs

A new engine cost depends on what the supplier means by new. We found two meanings in the listings.

• New genuine factory engine: the Ford parts dealer lists a brand new genuine Ranger PX 3.2 diesel engine for 2011 to 31 May 2015 at $8,416.83, down from an RRP of $10,100.20, with a Ford 12 month or 20,000 km genuine parts warranty. A PX2 3.2 listing for 6/2015 to 11/2018 showed a different part number and no price on the page
• New block and head: a Navara D40 YD25 long engine was listed at $4,495 with a new block and a new cylinder head, professionally built and inspected. Its heading says a 12 month warranty is included, while its terms say 3 months for parts, so ask which applies before you buy
• Dealer versus specialist: the Victorian specialist gives $4,000 to $7,500 for a new engine for popular Hyundai and Kia models from specialist suppliers and says dealership prices are substantially higher. That range does not apply to utes
• High end: the Western Australian workshop says some high-performance new engines cost $29,000 or more

Not every replacement engine is brand new. A reconditioned, rebuilt or used engine is often cheaper, and each carries different risks.

Used Engine and Fitting Costs

A used engine’s price depends on the donor vehicle, the engine code and what is included. Ask for the kilometres, whether it was tested before removal and what the warranty covers.

• Triton (4N15 2.4 turbo diesel): $4,950, listed as used, no kilometres stated, 3 month bare unit warranty. The listing says it fits selected models and typical model years from 2015
• BT-50 UP/UR 3.2 (P5AT): $6,250, build dates 10/2011 to 06/2020, described only as “good kms for age”, 3 month bare unit warranty
• BT-50 UN 3.0 (WEAT): $3,450, build dates 11/2006 to 09/2011, no kilometres stated, 3 month bare unit warranty
• Navara D40 2.5 diesel (YD25): $3,950, 169,080 km, “tested before dismantling”, turbo, injectors and EGR included, 3 month bare unit warranty and returns within 30 days if the seller is told first
• Wide spread on a parts marketplace: five Toyota engine listings we read ranged from $800 (a 2017 Corolla 2ZR-FE) to $4,840 (a RAV4 hybrid A25A). None showed GST, kilometres, condition or warranty on the page
• Used generally: the Victorian specialist gives $1,500 to $4,000 plus fitting, with unknown internal condition, and the Western Australian workshop gives $1,200 to $3,500 for the unit. Both are general ranges for mostly passenger vehicles

Most of the prices above do not state GST, so compare quotes on the same basis.

Reconditioned and Rebuilt Engine Prices

Suppliers use “reconditioned”, “rebuilt” and “remanufactured” in different ways, so ask what was done to the engine and whether the work is documented.

• Toyota Hilux diesel: $6,390 including GST as an exchange bare long motor, plus an $850 core fee refunded when a usable engine of the same type is returned (no external damage and no missing major components such as the cylinder head). The listing offers an unlimited kilometre, 12 month warranty with conditions: the fuel system must be tested by a diesel injection specialist and service schedules maintained
• Hyundai and Kia four-cylinders: $4,200 to $7,999 for an exchange reconditioned engine plus fitting, with a 12 month warranty on every reconditioned engine (Victorian specialist, July 2026)
• Western Australian workshop: remanufactured $2,500 to $5,000 and reconditioned around $4,000 (December 2025)
• Buying a rebuilt unit versus rebuilding yours: buying a unit means swapping engines. Rebuilding yours means the workshop strips, machines and reassembles your existing engine, which takes longer. See “Repair, Rebuild or Replace?” below

Labour, Removal and Engine Fitting Costs

Labour is the second big line, and the three workshops we read disagree on it.

What the sources say

• Victorian specialist (July 2026): fitting an engine bought outright typically costs $1,000 to $2,500 depending on the vehicle. Metropolitan workshop rates are roughly $100 to $150 an hour. A full rebuild takes roughly 15 to 25 hours
• Western Australian workshop (December 2025): 8 to 15 hours for a used, remanufactured or reconditioned replacement, 10 to 20 or more for a new engine and 2 to 7 days for the full job. Urban labour rates can reach up to about $200 an hour
• Sydney workshop (March 2025): a national average of around $100 an hour, with a labour range of $1,500 to $2,500 for a rebuild

What to ask for

• Hours and rate separately, not just a total, so you can compare quotes
• Removal and installation, and whether the quote covers moving ancillaries from the old engine to the new one
• What is included: fluids, testing, gaskets and any parts the workshop wants to replace while the engine is out. One wrecker’s warranty terms recommend replacing timing belts and oil seals before installation and say skipping that may void the warranty
• Fuel system work: the Ford listing says the installer needs the right tooling for fuel pump work so the timing is not disturbed, and recommends new or reconditioned injectors rather than reusing old ones
• Time off the road: the Victorian specialist says an exchange fit takes a few days and a rebuild one to three weeks

We found no verified labour time for a specific diesel ute, and the hourly figures above come from three workshops rather than a survey. Do not assume every installed quote is labour only.

Why Replacement Costs Vary by Vehicle

The same model badge can use different engines across its build years, and each engine has its own price. The listings we read show it clearly. Prices below are dated asking prices read on 22 October 2026, not sale prices, and none states kilometres unless noted.

Ford Ranger 3.2 diesel

• New genuine engine: $8,416.83 for PX Rangers built 2011 to 31 May 2015, without injectors, injection pump, ancillaries or gaskets
• Different build dates: a separate listing covers PX2 Rangers built 6/2015 to 11/2018 under a different part number, so the build date matters
• Related: Mazda’s BT-50 shares the 3.2 P5AT engine code in the used listing below. See our Ford Ranger gearbox issues guide if the gearbox is also a concern

Mazda BT-50

• UN, 3.0 diesel (WEAT): $3,450 used, build dates 11/2006 to 09/2011
• UP/UR, 3.2 diesel (P5AT): $6,250 used, build dates 10/2011 to 06/2020
• Why it matters: one model name, two engines and two prices. Mazda BT-50 engine replacement cost depends on which generation you have

Mitsubishi Triton

• 2.4 turbo diesel (4N15): $4,950 used, 3 month warranty on the bare unit
• Limit: the listing says it fits selected models and typical model years from 2015. It does not cover every Triton, so an older Triton needs its own engine code and quote. We found no dated price for one

Nissan Navara D40

• Used YD25 2.5 diesel: $3,950, 169,080 km, tested before dismantling, turbo, injectors and EGR included, built 05/2010 to 08/2015 (VIN reference VSK)
• New block and head, long engine: $4,495
• Euro 5 emissions type, long engine assembly: $4,950, with no inclusions listed
• Why it matters: the seller asks you to confirm engine code, build year and emissions type before ordering. See our Nissan Navara problems guide for known issues

Toyota Hilux diesel

• Reconditioned exchange: $6,390 including GST plus an $850 refundable core fee
• Why it matters: one listing covers the 2.4 (2L), 2.8 (3L) and 3.0 (5L) diesels, and the core must be the same engine type. See our Toyota Hilux common problems guide

VE Commodore, Mazda 3 and Holden Barina

• VE Commodore engine replacement cost, Mazda 3 engine replacement cost and Holden Barina engine replacement cost: we did not find a dated listing or a published cost for these, so we give no figure
• What to do: ask for a written quote that names the engine code, the build date and what is included

Factors that change the price

• Engine code and build date: not just the model name
• Fuel and induction: petrol, diesel and turbo engines are priced differently, and the Victorian specialist says diesels and turbo engines push rebuild costs higher
• Condition and inclusions: new, reconditioned or used, complete or bare
• Where the work is done: the Western Australian workshop says metropolitan labour rates are generally higher than regional ones but gives no regional figure
• Whether other work is needed: a rebuild’s cost depends on what the strip-down finds

Replacement Versus an Engine Swap

People use “engine swap” for two different jobs, and the cost and rules differ.

• Like-for-like replacement: the same engine, or an engine the manufacturer offered for that model, put in place of the failed one
• Engine swap or conversion: a different engine from another model, or a more powerful engine, which is a modification

What the sources say

• National code: VSB 14 Section LA Engines (version 2.0, 1 January 2011, a copy hosted on a Queensland TMR site) lists fitting a new, used or reconditioned engine as a basic modification that needs no certification provided the general requirements are met. It lists engines more than 120 per cent of the original power or mass, performance engines and engines from non-original sources as needing certification. It also says a more powerful engine needs suitable upgrades such as brakes and front suspension. Check for a newer version
• Queensland (page updated 1 July 2026): “like for like replacement of engines” is a basic modification that needs no approval or certification if the vehicle still meets the applicable standards. “Engine upgrades” are complex modifications that need certification by an approved person
• NSW: Vehicle Standards Information 6 (the 2013 version we read) lists an engine “not of an original family of engine for the series of models”, or one more than 20 per cent larger than the largest original optional engine, as needing certification. Check the current version
• Victoria (undated page): an identical engine, or an option the manufacturer allowed for that model, needs a declaration and a change of vehicle details form. An engine the manufacturer did not offer needs an inspection and more documents
• Western Australia: a like-for-like engine change needs no modification permit but needs a change-of-details form, and a different engine needs approval (Department of Transport, from the research for our Japanese import engines guide)

What a swap can add to the budget

• Engineering and certification, where the rules require it
• Mounts, wiring, engine management, fuel system, cooling and exhaust work
• Upgrades to brakes and suspension if the new engine is more powerful
• Emissions compliance. VSB 14 Section LA says a different engine design should generally be fitted with its donor vehicle’s emission control system as a complete package

We found no verified Australian price for engine swaps or conversions. So engine swap cost and labour should be budgeted separately once the scope is known, using written quotes. If you ask how much an engine swap costs, the honest answer is that it depends on which engine, which vehicle and how much of the vehicle has to change.

Repair, Rebuild or Replace?

Start with a written diagnosis. A component repair, a rebuild and a replacement answer different problems, and each quote should say what it covers.

Rebuild your existing engine

• Victorian specialist (July 2026): $3,500 to $5,500 for a four-cylinder rebuild including parts, machining and labour, with a typical rebuild near $4,000 for most Hyundai and Kia four-cylinders. Time off the road is one to three weeks
• Sydney workshop (March 2025): $2,500 to $4,500, with labour of $1,500 to $2,500
• Western Australian workshop (December 2025): $2,500 to $6,000 or more
• What is included: stripping to a bare block, machining the block, crank and head as needed, and reassembly with new bearings, rings, gaskets, seals and timing components (Victorian specialist)

Replace with an exchange or used engine

• Exchange reconditioned: $4,200 to $7,999 plus fitting for Hyundai and Kia four-cylinders, with fitting taking a few days (Victorian specialist)
• Used: from $1,200 to $3,500 for a general unit (Western Australian workshop), or the ute listings above at $3,450 to $6,250

Repair a component

• Head gasket: $800 to $3,200, with early cases $900 to $2,500 (Western Australian workshop)
• Camshaft: $1,500 to $3,000 (Western Australian workshop)

How to compare

• Ask each workshop for a written quote that names the work, the parts and the warranty
• A rebuild’s cost depends on what the strip-down finds, so ask how the price changes if more is damaged
• Compare a repair quote with a replacement quote that has the same inclusions, including fitting
• Consider the vehicle’s value and how long you plan to keep it. That is our suggestion, not a sourced rule

Is it cheaper to buy a complete engine or rebuild with a new head and gasket? We found no source that compares the two for a specific vehicle, so the only reliable answer is two itemised quotes.

Choosing a Compatible Replacement Engine

The right engine matches your vehicle’s code, build date and equipment, not just its model name.

Match these before you buy

• Engine code: the Hilux listing covers three different diesels, and the BT-50 listings cover two different engines
• Build date or VIN: three of the listings we read ask you to send your VIN before bidding, and the Ford PX and PX2 Ranger listings are separate by build date
• Emissions type: the Navara Euro 5 long engine is sold for “Euro 5 compliant models”, and the BT-50 UN listing says emissions are “Euro 3 / Euro 4 (market dependent)”. Confirm yours
• Transmission and drivetrain: the BT-50 listings say drivetrain and transmission are variant dependent
• Ancillaries and fuel system: the Hilux listing is a bare long motor with no accessories or fuel system, and recommends a reconditioned fuel system
• Engine number: the Ford PX2 listing asks you to record the new engine number, found on a small plate at the rear of the driver’s side of the block near the bellhousing bolts. Keep it with the invoice

Registration and emissions rules

• Registered details: each state we checked has a process for recording an engine number change. Queensland says to notify TMR within 14 days using Form F3524, and Victoria says to notify within 14 days. Service NSW lists engine details such as the engine number among the details you can change at a Service NSW centre and states no deadline. Fees may apply
• Inspections: Victoria says VicRoads will need to inspect the vehicle to confirm the new engine details, unless you provide a current certificate of roadworthiness or VASS approval certificate that includes the new engine number
• Other states: we did not verify South Australia, Tasmania, the ACT or the Northern Territory
• Emissions: where the rules treat the change as a modification, VSB 14 Section LA says the vehicle should still meet the gaseous and noise emission standards, and that aftermarket engine management does not guarantee compliance with the relevant ADR unless that combination was ADR tested (2011 version)

What an Engine Replacement Involves

A replacement is more than lifting one engine out and another in.

• Diagnosis: confirm the engine is the problem and what has failed. A written diagnosis helps you compare repair, rebuild and replacement
• Choose the engine: new, reconditioned, used or a rebuild of your own. Exchange engines, like the Hilux listing, need your old engine returned as the core
• Removal and fitting: the workshop removes the old engine, moves over or renews parts, fits the replacement and tops up fluids. A supply-and-fit package covers the engine, installation, fluids and testing (Victorian specialist)
• Testing and paperwork: the workshop tests the vehicle, you keep the invoice showing the engine number and you update your registration details
• Time: two to seven days for the full job (Western Australian workshop), or a few days for an exchange fit and one to three weeks for a rebuild (Victorian specialist)

What a workshop needs to quote you

• Your VIN and registration, so the engine code and build date can be confirmed
• The engine code from the engine plate or paperwork
• The kilometres and what is wrong, ideally with a written diagnosis
• The transmission type and whether it is also an issue
• The state where the vehicle is registered

Engine Replacement Quote Checklist

Ask for each of these in writing and confirm it against the actual quote.

• Engine code and condition: new, reconditioned or used, and the kilometres if used
• Inclusions: bare long motor or complete engine, injectors, injection pump, turbo, EGR and ancillaries
• Labour: hours and hourly rate, plus whether removal and installation are in the price
• Fluids and consumables: oil, coolant, gaskets and filters
• Extra parts: timing belt or chain parts, oil seals, mounts, radiator and clutch
• Freight: to your postcode
• Tax: whether the price includes GST
• Core: the core fee, the return rules and the refund timing
• Warranty: length, whether it covers the bare unit only, whether labour is covered, and the conditions that void it, such as overheating, incorrect installation or skipping recommended parts
• Additional work: what happens if the workshop finds more damage once the old engine is out
• Registration paperwork: who handles the engine number change

The Western Australian Consumer Protection page (updated 4 December 2023) advises asking for a written quote or estimate detailing the work and cost, says an accepted quote forms a contract binding both sides, and says you should not automatically authorise additional repairs. It also says the Australian Consumer Law requires repairs to be done with due care and skill, including when second-hand parts are used. That page covers Western Australia, so check your own state’s consumer affairs body.
