Mechanics tutor David Walker's Level 2 students got to work this week removing a car's cylinder block and dismantling its parts to see how each piece was put together and how it worked. Here's how it's done . . . being extremely careful not to get fingers or hands pinched between a swinging engine and the engine bay - most engines weigh hundreds of pounds!
1. Remove the hood to access connections or bolts and give space for the engine lift out of the engine bay using a cherry picker or engine hoist
2. Drain the engine oil and coolant into separate containers for recycling
3. Disconnect the intake, exhaust and coolant lines etc. Older, carburetted motors may have fairly few wired connections to contend with, while brand new cars often have many electrical connections
4. Unbolt the engine from the transmission - loosen each bolt a bit at a time until they are all hand loose before removing them
5. Disconnect the motor mount bolts. The engine will now be supported by the cherry picker or engine jack.
6. Either raise or lower the engine from the engine bay.
All steps completed in a couple of hours . . . David said: "The students will spend the next couple of weeks examining the engine block parts to carefully understand how they work individually and as one unit."
