How Are Engine Hoists Used? A Step-By-Step Guide To Safe Engine Removal

At its core, an engine hoist is a portable crane designed specifically for lifting and maneuvering heavy engines out of and into a vehicle's engine bay. It uses a hydraulic jack to raise a boom, which has a chain and hook at the end, all mounted on a wheeled frame for mobility.

An engine hoist is more than a simple lifting device; it is a tool for precise and safe maneuvering of an engine. Proper setup, balance, and a methodical approach are paramount to prevent damage to the vehicle, the engine, and most importantly, yourself.

How are engine hoists used? A Step-by-Step Guide to Safe Engine Removal

Preparing for the Lift

Before the hoist touches the engine, proper preparation is the most critical phase of the job. Rushing this stage is the most common cause of problems.

Choosing the Right Hoist

Most workshops and home garages use a floor crane hoist, often called a "cherry picker." The single most important specification is its weight capacity. Always ensure the hoist's capacity significantly exceeds the combined weight of the engine and transmission if you are pulling them together.

Securing the Vehicle and Workspace

The vehicle must be on a hard, level surface like a concrete garage floor. Chock the wheels that will remain on the ground and ensure you have ample, clear space around the engine bay to move the hoist freely.

Prepping the Engine

The engine must be completely disconnected from the vehicle. This involves draining all fluids (oil, coolant), disconnecting all electrical harnesses, fuel lines, vacuum hoses, and exhaust components. Finally, the transmission and engine mounts must be unbolted.

The Lifting Process: Step-by-Step

With the engine fully disconnected, the hoist can be brought in to do its work. The key here is to move slowly and deliberately.

Positioning the Hoist

Roll the hoist into position so the boom is centered over the engine. The legs of the hoist should extend as far under the vehicle as possible to provide a stable base of support.

Attaching Chains and Leveler

Securely attach the lifting chains to the manufacturer's designated lifting points on the engine block or cylinder head. Using an engine leveler—an adjustable bar between the hook and the chains—is highly recommended as it allows you to tilt the engine during the lift.

Finding the Center of Gravity

Before lifting, ensure the engine is balanced. Adjust the chain positions or the leveler so the lifting hook is directly above the engine's center of gravity. When you apply a small amount of tension, the engine should not try to tilt aggressively in any direction.

Operating the Hydraulic Jack

Use the pumping handle to slowly operate the hydraulic jack, which will raise the boom. Watch the engine closely as it takes the weight. Listen for any unusual sounds and check for any forgotten connections.

Clearing the Engine Bay

Lift the engine just enough to clear the mounts and the top of the engine bay. Once it is clear, do not lift it any higher than necessary. Slowly and carefully roll the hoist backward, guiding the engine out of the vehicle. Immediately transfer the engine to a secure engine stand.

Understanding the Pitfalls and Safety Criticals

Using an engine hoist is straightforward but carries inherent risks that must be managed with care and attention.

Risk of Instability

The greatest risk is the hoist tipping over. This is almost always caused by an unbalanced load, trying to lift beyond the hoist's capacity, or attempting to roll the loaded hoist over an uneven or cluttered surface.

The Inevitable "Swing"

A suspended engine will swing freely at the end of the chain. All movements—both lifting and rolling the hoist—must be slow and steady to prevent the engine from swinging and damaging the vehicle body.

Never Work Under a Suspended Load

A hydraulic system can potentially fail. Never place any part of your body under an engine that is supported only by the hoist. Once the engine is out, it should be immediately secured to a proper engine stand.

Foldable vs. Fixed Frames

Foldable hoists are excellent for saving space in a home garage. However, they may require more care during setup to ensure all locking pins are secure. Fixed-frame hoists are typically more rigid and stable but require significant dedicated storage space.

Applying This to Your Project

Your specific goal will determine the best approach to using and selecting an engine hoist.

If your primary focus is a one-time engine swap: Renting a high-quality 2-ton hoist and an engine leveler is the most cost-effective and safest option.
If your primary focus is frequent, heavy-duty work: Investing in a robust, non-foldable hoist with a high weight capacity provides maximum stability and longevity.
If your primary focus is home garage use with limited space: A quality foldable hoist offers a practical balance between capability and efficient storage.

By treating the engine hoist as a tool for precision control, you can tackle even the most demanding engine work safely and confidently.

Summary Table:

Key Step	Critical Action	Why It's Important
Preparation	Disconnect all fluids, hoses, and mounts.	Prevents damage and ensures a clean lift.
Positioning	Center the hoist and extend legs under the vehicle.	Provides a stable base to prevent tipping.
Lifting	Use an engine leveler and lift slowly.	Allows for precise control and prevents swinging.
Safety	Never work under a suspended load.	Protects against potential hydraulic failure.
