How to Remove a Car Engine

Here's how to remove an engine and transmission from a car for service.

Removing the transmission and/or engine assembly is usually required for a complete rebuild or to service major body components such as the frame or wiring harness. The vehicle demonstrated here is a RWD Infiniti G35 sedan, which is similar to many RWD vehicles.

The first stage of removing the engine is preparation which includes removing all small accessories or subsystems around the engine bay. The front bumper, rebar, radiator support, radiator and air intake are removed. The wiring harness is disconnected from the ECU with two connectors and fished through the firewall instead of disconnecting every single engine component and clip. The A/C system is drained and disconnected.

The second stage is preparation underneath the vehicle, which includes removing the exhaust at the headers, drive shaft, shifter linkage and transmission mount. If the engine and transmission are being dropped down, then the steering rack and lower control arms are disconnected.

The final stage is removing the engine and transmission assembly. If the engine is dropped down and out, as demonstrated in this video, then the subframe bolts are removed and the assembly is slowly lowered onto a floor jack. If the engine is being lifted out, an engine crane with a leveler must connect to strong engine attachment points at both ends.

Removing the engine on a RWD car is not difficult, as this job should take 4 - 6 hours if all tools are available and there aren't any rusty oversights.
