Step-by-Step Engine Removal
Once you’ve prepared yourself and your workspace, it’s time to start the engine removal process. Here’s a step-by-step guide to follow:
Step 1: Remove the Engine Mounts
Start by removing the engine mounts, which are responsible for holding the engine in place. You’ll typically find these mounts attached to the engine block and the car’s chassis. Use a wrench or socket to loosen and remove the mounts.

|---|---|
| Engine Mounts | Loosen and remove with a wrench or socket |
| Transmission Mounts | Loosen and remove with a wrench or socket |
Step 2: Disconnect the Exhaust System
Next, disconnect the exhaust system from the engine. This will involve removing the exhaust pipes, muffler, and any other components that connect to the engine. Use a wrench or socket to loosen and remove the exhaust system components.
Step 3: Remove the Timing Belt or Chain
Remove the timing belt or chain, which connects the crankshaft to the camshaft. This will involve loosening and removing the tensioner and pulleys. Be careful not to damage the timing belt or chain during this process.
Step 4: Disconnect the Cooling System
Disconnect the cooling system from the engine, including the radiator, hoses, and water pump. Use a wrench or socket to loosen and remove the cooling system components. (See Also: How to Remove Car Paint Scratches? Easy Repair Guide)

How To Remove An Engine
Removing an engine from a car is not as simple as connecting a hook and ripping it out. Before you get to that part, prior preparation is required.
It’s highly recommended that you find shelter whilst removing an engine from a car. Not only will it prevent water or debris getting into the engine but it also helps having bright LED garage lights, which helps you see all the nuts and bolts.

Engine Removal Preparation
Preparation is important as it ensures that everything goes smoothly when removing an engine from a car. Below are 8 steps that we highly recommend:
- Disconnect and remove the battery. As you will be coming across plenty of wiring and sensors, you don’t want any power going through them.
- Remove the hood. Not strictly necessary but the engine may not pass through.
- Empty fluids from engine. As if you were changing the oil, start by removing the oil and after that remove the car antifreeze via the radiator peacock.
- Disconnect the coolant lines. The hoses will be connecting from the radiator to the engine and these will need to be removed.
- Disconnect the exhaust and intake. The intake will be connecting from the air filter to throttle body. To remove the exhaust, remove the bottom bolts of the exhaust manifold.
- Remove connected wiring. The age of your car will determine how much wiring there will be. Remove all wiring that you can see connected to the engine.
- Pull apart transmission and engine. Place a floor jack under the transmission and then start unbolting the bolts that pass through the bell housing of the transmission into the engine. The transmission will drop once the bolts are removed.
- Disconnect engine mounts. Use a wrench to remove the bolt holding the mounts.
It’s worth mentioning that all engines are different and some vehicles may require further preparation before you go ahead and remove the engine.
Engine Removal With a Hoist
The safest and best possible method of removing an engine is to use a hoist, which is also known as an engine crane. Some of the best rated engine hoists are capable of lifting over 4,000 LBS up to 40 feet in the air and are a worthwhile investment.
Once the engine has been prepared for removal, you can attach the hook from the hoist to the engine block. Most engine blocks will have a loop design on the engine block that is specifically designed for lifting the engine. Once attached, you can then slowly begin to lift the engine using the power from the hydraulic cylinder, chain or electric motor.
As the engine is being lifted, you will want to doing it as slowly as you can and check for any components still attached. Once it’s confirmed that everything has been removed, you can begin to lift the engine completely out of the car.
How To Remove Engine Without a Hoist
It is possible to remove an engine with no hoist or crane. It involves getting the car high up in the air via jack stands, which gives you an idea of where this is going.
Following the engine removal preparation mentioned above, you will then need to place the jack under the oil pan, which is where the engine lifting will begin.
You may need to increase the height of the jack with a thick blank of wood in order to reach the oil pan. You will then need to jack the oil pan up until the engine is no longer on the mounts. At this point, you can unbolt the mounts.
You are now able to slowly lower the jack whilst checking everything has been disconnected. Once the jack is at the bottom, you will then need to drag the engine from below the car. This is not an easy job and this is the reason why engine hoists were invented.
If you are lucky enough to have a home garage car lift, we highly recommend that you use it instead of the jack stands. It will make your life much easier and involves less crawling around underneath the car and additional lifting control.
Portability of the Engine Once Removed
When removing an engine from a vehicle, you are more than likely going to have to move it around. Some engine hoists have multiple steel casters at the bottom (as shown above), which allow you to move the engine quite easily around the garage. Alternatively, if you are not using a hoist, you can place the engine on some heavy duty car dollies.
Conclusion
Removing an engine from the car is not the hardest thing in the world. That being said, it’s much easier to remove an engine from an older car than it is the modern cars.
Due to the availability of crate engines, removing an older engine with a brand new one is very popular. Many classic car enthusiasts carry out this major modification once their current engine is beyond repair.
A word of advice, if you are replacing the engine be extra careful with the fuel lines and electric cables. These can be brittle and break easily, which can be hard to diagnose when your new engine is not starting due to the damage.
