HOW IT WORKS

What is an engine assembly?

An engine assembly typically refers to the combination of components that make up the engine in a vehicle. This includes the engine block and all of its internal parts, as well as some of the accessories that are bolted to the engine, like the cylinder heads, intake manifold, water pump, exhaust manifold, and the like.

It is common for a technician to make repairs to an engine and its components. The pistons, crankshaft, valves, camshafts, and other parts can all be replaced and by a qualified technician. But sometimes an engine is better off being replaced as an assembly, whether because it is so severely damaged or because it is more economical to do so. Precisely which components are included in the term “engine assembly” can differ somewhat by vehicle manufacturer or retail supplier of an engine.

HOW IS THIS SERVICE PERFORMED?

How is a an Engine Assembly Replacement done?

Engine assembly replacement is a difficult and lengthy process. It requires special tools, techniques, and experience. The procedure to replace an engine in most modern vehicles necessitates that the vehicle be safely lifted and supported in the air for access to a number of components. It also requires that several systems be disassembled or removed. For instance, the cooling system must be drained. The AC system must be evacuated. The suspension system must be at least partially disassembled. The transmission or transaxle must be removed.

The process for removing and replacing an engine generally involves the following (abbreviated) steps:



  • Disconnect and remove the battery
  • Unplug all of the wiring connected to the engine
  • Drain all fluids associated with the engine assembly
  • Remove external components, such as the alternator, AC compressor, throttle body, and exhaust manifold
  • Support the engine assembly with an engine lift and unbolt the engine mounts
  • Separate the engine from the transmission (in many cases, the engine and transaxle are removed along with the engine cradle, steering components, and suspension)
  • Remove the engine assembly
  • Installation is generally in the reverse order of removal, but additional steps are often required to dress the new engine with many of the components from the old engine. Special alignment procedures must be followed when it comes to reattaching the transmission to the engine. The new engine may also need electronic programming with a dealer-level scan tool before it can be operated and placed back into service.

COMMON SYMPTOMS

An engine assembly replacement is typically indicated only when there are signs of catastrophic damage inside your engine. It might be time for a new engine if you notice the following symptoms:

A loud knocking noise coming from the engine while it is running

Chattering sounds in the engine that get worse when the engine warms up

A significant amount of metal shavings are found in your oil and oil filter

Your engine loses oil pressure, as indicated on the pressure gauge or light on your dashboard

Other questions customers ask

Is it better to repair an engine or replace it?
Whether it is better to repair an engine or replace it depends on a variety of factors such as the mileage or wear on the engine, the age of the engine, the symptoms the engine is presenting, and how expensive replacement parts and labor are for the engine. This is a conversation best left to the vehicle owner and a qualified technician.
How many miles will a rebuilt engine last?
A rebuilt engine should last just as long as the original engine, as long as the rebuild process was completed carefully and the break-in process is followed.. Its lifespan is also influenced by adherence to manufacturer recommendations.
Does a new engine mean new mileage?
No. Replacing the engine does not mean that your vehicle can have the odometer rolled back to reflect the age of the engine. Your mechanic is not allowed to reset or modify the odometer in any way. Federal law prohibits tampering with the odometer of a vehicle.
