How to Use an Engine Hoist Safely (Step-by-Step Guide)
An engine hoist makes pulling an engine possible in a home garage, but it also puts several hundred pounds of metal in the air a few feet from your hands. Most engine hoist accidents come from rushing: the wrong boom setting, a missed bolt, or a load that swings when the hoist rolls. This guide walks through the process step by step, so you can lift an engine out and back in safely.
Always follow your hoist’s manual and your vehicle’s service information. The steps below cover the general process that applies to most cars and light trucks.

What You Need
- An engine hoist rated well above your engine’s weight at the boom setting you will use
- A load leveler, or grade-rated lifting chain with proper bolts and washers
- An engine stand, pallet or sturdy cart to set the engine on
- A floor jack and heavy duty jack stands if the vehicle needs to be raised
- Drain pans, labels or tape for wiring and hoses, and a helper if possible
Step 1: Prepare the Vehicle
Park on flat, solid concrete with plenty of room in front of the vehicle for the hoist to roll back. Disconnect the battery. Drain the coolant and, depending on the job, the oil and transmission fluid. Remove the hood so it does not block the boom, and take off anything in the way, such as the radiator, fans or intake ducting.
Label every electrical connector and hose before you disconnect it. Photos from a few angles help a lot during reinstallation.
Step 2: Disconnect Everything Between Engine and Vehicle
Work through the engine bay and underneath the vehicle. Typical connections include the wiring harness and grounds, fuel lines, vacuum and coolant hoses, throttle linkage, air conditioning compressor (often unbolted and set aside rather than opened), exhaust at the manifolds or headers, and either the transmission bellhousing bolts or the transmission mounts if they come out together. Leave the engine mounts for last.
Step 3: Set Up the Hoist
Unfold the hoist and lock the legs and mast pins in place. Choose the shortest boom setting that still lets the hook sit directly above the engine’s center of gravity, then check the capacity stamped at that position. If the rating is close to the engine’s weight, stop and rethink the plan before going further. Remember that the rating drops as the boom extends, so the number on the box only applies at the shortest setting.
Roll the hoist in so the legs slide under the front of the vehicle and the boom sits over the engine. Close the release valve before lifting.
Step 4: Attach the Chain or Leveler
Bolt the chain or load leveler to solid lifting points on the engine. Many engines have factory lift brackets. Otherwise, use strong points such as cylinder head or intake manifold bolt holes that your service manual approves. Use grade 8 bolts (or the metric equivalent) with hardened washers, and thread them in fully, at least as deep as the bolt’s diameter and preferably more.
Position the attachment points so the engine hangs level, or slightly tilted the way you need for removal. A load leveler lets you adjust the angle after the engine is in the air, which is much easier than resetting chains.
Step 5: Take Up the Slack and Remove the Mounts
Pump the ram until the chain is tight and the hoist is just starting to carry some of the engine’s weight. With the engine supported this way, remove the engine mount bolts. The engine should not drop or shift when the last bolt comes out.
Step 6: Do a Test Lift
Raise the engine one or two inches and stop. Check that the chain and bolts are secure, the engine is balanced, and nothing is still connected. Look underneath and around the back of the engine for a forgotten ground strap, hose or wiring clip. This short pause is the most important step in the whole job.
Step 7: Lift and Guide the Engine Out
Raise the engine slowly while your helper watches the clearance around the radiator support, firewall, brake lines and body. Tilt the engine with the leveler as needed and separate it from the transmission if the transmission stays in. Lift only high enough to clear the front of the vehicle.
Step 8: Roll Back and Lower
Lower the engine as close to the floor as practical before rolling the hoist. Move slowly, push from the mast rather than the boom, and avoid cracks, drains and slopes. Lower the engine onto an engine stand, a pallet or a sturdy cart, and open the release valve gradually so it comes down smoothly.
Installing the Engine
Reinstallation follows the same steps in reverse. The hardest part is usually lining the engine up with the transmission input shaft or the mounts. Use the leveler to match the transmission angle, lower in small steps, and never force the engine into place with the hoist. If it will not seat, lift slightly and adjust the angle rather than pushing.
A Scenario Worth Knowing About
Say you lift the engine two inches, everything looks fine, and you keep going. At about a foot, the engine suddenly tips backward and the hoist lurches. The cause is often something small: a transmission cooler line or ground strap still attached at the back of the engine, pulling it off balance as the slack runs out. This is why the test lift and a slow, watched lift matter so much. If anything binds, stop, lower slightly, find the connection, and free it before continuing. Never pull harder with the hoist to break something loose.
Engine Hoist Safety Rules
- Never put your hands, feet or body under a suspended engine.
- Use the shortest boom setting that reaches, and stay well inside its rating.
- Use only grade-rated chain and hardware, never rope or ordinary bolts.
- Keep the load low whenever the hoist is moving.
- Keep children, pets and bystanders out of the work area.
- Do not leave an engine hanging longer than necessary.
FAQs
Can one person use an engine hoist?
It is possible, but a helper makes the job safer. One person can work the ram while the other watches clearances and guides the engine.
Do I need a load leveler?
It is not strictly required, but it makes removal and especially installation much easier, because you can change the engine’s angle while it hangs instead of resetting chains.
Where should I attach the chain on an engine?
Use factory lift brackets if your engine has them. Otherwise, use strong bolt holes approved in your service manual, usually on the cylinder heads or intake manifold, with grade 8 bolts threaded in fully.
Should the transmission come out with the engine?
It depends on the vehicle and the job. Pulling them together can be faster, but it adds weight and makes the load longer and harder to balance. Check that your hoist’s rating at the needed boom setting covers the combined weight.
Conclusion
Using an engine hoist safely comes down to preparation and patience. Disconnect everything, choose the shortest boom setting with plenty of margin, use proper hardware, do a test lift, and keep the engine low when moving. With the right hoist and a good stand, pulling an engine at home is a manageable job. Before you start, make sure the vehicle is supported with reliable heavy duty jacks.
