Engine Replacement
Engine replacement means taking out the failed engine and fitting another one of the same type: brand new, reconditioned or used. It makes sense when the block or crankshaft is damaged, or when a rebuild would cost more than the car can carry. If the damage is limited to rings, bearings or the head, an overhaul of your own engine may be the better route, and we put both on the table.
- Written quote after diagnosis, before work starts
- Usually 2-5 days once the engine is in hand; sourcing a used or reconditioned unit can add time
- Pickup and delivery from your door
- Convenience fee applicable · shown on your written quote
- Diagnosis free with repair
Signs you need engine replacement
- The engine has seized and the starter will not turn it over
- A loud knock from low down that started suddenly, often after the oil light came on
- A hole in the block, or oil and coolant mixed into a thick brown paste
- The engine ran without oil or coolant and stopped on the road
- A workshop has told you the crankshaft or block is beyond machining
- A rebuild quote that is close to what the car is worth
What usually causes it
Oil starvation
A slow leak, a missed top-up or a failed oil pump can leave the bearings dry. They overheat in seconds, spin in their housings and lock the crank. By then the damage usually reaches beyond what new shells can fix.
Driving on after overheating
Carrying on with the gauge in the red can crack the block or head, and pistons can seize in their bores. Aluminium blocks distort under that heat, which makes a good repair hard to achieve.
Water ingestion
Driving through a flooded underpass can pull water into the intake. Water does not compress, so the piston stops hard and a connecting rod bends or snaps, sometimes through the side of the block.
Timing failure on an interference engine
When a timing belt or chain breaks on many modern engines, the valves meet the pistons. Bent valves alone can be fixed in the head, but broken pistons or a damaged block move the job towards a replacement.
How we do engine replacement
- 1
Confirm the engine is finished
We check whether it turns, look at the oil and coolant, and where possible run compression and borescope checks. If the damage is repairable in the head or with an overhaul, you hear that before any engine is ordered.
- 2
Match and price the options
We read the engine code and the car's build details, then price a new, reconditioned or used unit that fits. The written quote lists each option with its source, mileage where known, the supplier's warranty and the labour, so you choose.
- 3
Swap the engine
The old engine comes out with the gearbox or on its own, depending on the car. Sensors, brackets and ancillaries are moved across or renewed, and we fit new mounts, seals, gaskets and filters where they are due.
- 4
Fill, code and road test
The new engine gets fresh oil and coolant, and the cooling system is bled. Some cars need the control unit coded or adapted to the engine. We check for leaks and fault codes, then road test before handover.
By make and model
Hyundai / Kia
Theta II 2.0 and 2.4 GDI engines were the subject of well-publicised bearing failures and recalls in some markets. Ask the dealer whether your engine is covered before paying for a replacement yourself.
Toyota / Lexus
Popular engines such as the 2GR V6 are widely available as used units from Japanese-market cars, which keeps the used route realistic. The engine code still has to match, as versions differ in ancillaries and electronics.
In Dubai, Sharjah and Ajman
A failed engine in the Emirates is often heat or water related: long idling with the AC on in summer traffic, a cooling fault ignored on the highway, or a run through a flooded road after a storm. Used engines here come largely from imported Japanese and American cars, so quality varies a lot. Ask for the engine number and the supplier's warranty in writing, and keep both with the car's papers in case a buyer or insurer asks where the engine came from.
Questions about engine replacement
Should I replace the engine or rebuild it?
If the block and crank are sound, an overhaul of your own engine is often fair value. If the block is cracked or the crank is scored past machining, a replacement is the practical answer. The engine overhaul page explains the rebuild route; we price both when both are possible.
What is the difference between new, reconditioned and used?
A new engine comes from the maker or a parts supplier and has never run. A reconditioned one has been stripped, machined and rebuilt with new wearing parts. A used engine comes out of another car as it was. Price, warranty and lead time differ, and the quote states which one you are getting.
How do you know a used engine is healthy?
We check the engine code, the mileage the supplier gives, oil condition, signs of overheating and, where the engine is accessible before fitting, compression. No check makes a used engine as certain as a new one, which is why the supplier's warranty matters.
Will my car need programming afterwards?
Some do. Cars with immobilisers or engine-specific calibrations may need coding so the control unit accepts the engine or its sensors. We check this when matching the engine and include it on the quote.
Can you collect a car that will not start?
Yes. A car with a failed engine comes to the workshop on a recovery truck. We handle the transport, and the diagnosis is free if you go ahead with the replacement.
