The final step in this phase of the engine replacement is to actually remove the engine from the vehicle's engine compartment using an engine-hoist (figure A). Important: Included below are the steps in this automotive procedure as shown in the episode. These steps are general guidelines that are applicable to most vehicles. With any particular vehicle, there may be procedures, specifications, settings, tolerances, components, etc. that are specific to that vehicle. There are also variations according to the type and brand of repair kit you select. Always consult your vehicle's service manual when undertaking significant automotive repairs, and read and follow the manufacturer's directions and precautions that come with your kit or replacement parts. Safety Alert: Always wear eye protection, and follow proper safety precautions, when working with power tools and when working beneath a vehicle.
Pulling the Engine
- With the car removed from the jack-stands, preparation gets underway for removing the engine using the hoist. It's preferable to remove the engine from the vehicle with the vehicle resting on the ground, as it could become unsteady on the jack-stands once the weight of the engine is lifted out.
- Engine hoists are adjustable, so that the boom can be shortened or lengthened to achieve the proper orientation over the engine (figure B).
Important: Make certain that the length of the legs is extended to match the extension of the boom. Otherwise the hoist could become unstable when it's supporting the weight of the engine. - To remove the engine, the upper motor mounts must be loosened, as well as the bell-housing bolts (figure C). One bell-housing bolt is left in until just before the engine is lifted.
- A heavy chain is used to attach the engine to the hoist. One end of the chain is attached to a stud on the top of the engine (figure D), and the other is attached to one of the head-bolts on the opposing side of the engine (figure D ).
Important: Make sure to attach the chain to bolts that are hard enough to support the weight of the engine. - With the chain attached and adjusted to the proper length (figure F), a transmission jack is placed beneath transmission pan (figure G).
- With a slight amount of tension on the chain, remove the last bell-housing bolt.
- Now, with two people working in unison -- one operating the hoist and one guiding the engine -- the engine is lifted straight up (figure H), then rolled clear of the vehicle.
