Replacing the engine in your vehicle can vary in difficulty depending on your mechanical experience. For more proficient home mechanics, the installation will seem familiar. Installations differ based on the vehicle, the following tips can be applied across most makes and models. 

How to Replace a Car Engine

1. Remove the Old Engine

Before removing the heart of your car drain all fluids, such as oil and coolant. Disconnect the intake, exhaust, and coolant lines, as well as the electrical wiring. Be careful not to damage sensitive connectors as you separate them. Unscrew the transmission, but make sure you don’t strip the bolts, as this will make them more difficult to remove.

If you're using a cherry picker, put the chains in place before disconnecting the motor mount bolts. If you plan to lower the engine through the bottom of your vehicle, consider placing a jack beneath it. 

2. Compare the Two

Once you have removed the old motor, perform a visual inspection, comparing it with the replacement to ensure they match. Even replacements made by the same company can differ depending on their model or year.

Confirm that the new bolts match the old to ensure it will fasten in the same spots. Check the placement of components such as the steering, air conditioning, intake, exhaust, and motor mount brackets.

3. Prep the New or Used Engine

This is a perfect time to inspect & replace any consumable parts such as hoses, belts, gaskets, seals (even on the transmission).  If not provided; always install a new thermostat, water pump, front and rear engine main seals.  Purchasing ROE (Recycled Original Equipment) engines can save you a ton but consumable parts are best bought new!

4. Install the New One

Reverse the method used to remove your old motor, either lowering or raising it into the vehicle bay, carefully guiding it over the input shaft of the transmission. Once in place, secure the motor mount bolts, ensuring they’re tightly fastened before removing your lift.

Connect the transmission carefully ensuring proper gap with torque converter.  Reassemble your cooling system, exhaust manifold, radiator, belts, accessories, fuel lines, intake manifolds, and the battery. Thoroughly inspect before refilling fluids or cranking your new engine.
