Exam 10: Engine Disassembly and Cleaning

A buildup of sludge in the rocker area indicates a poor maintenance schedule and is a signal to look for wear on other components.

Parts washers are often called ____________________ tanks.

Technician A says that compared to RWD cars, engines in FWD cars are easier to remove because they don't have large assemblies such as engine cradles, suspension components, brake components, splash shields, or other pieces that need to be disassembled or removed. Technician B says in certain vehicles the engine and transmission must be removed together as a unit. Who is correct?

Technician A uses masking tape and a marking pen to label electrical connectors and vacuum lines. Technician B puts all the nuts and bolts and other fasteners into a big coffee can and sorts them out during reassembly. Who is correct?

While removing a cylinder head, Technician A keeps all rocker arms and pushrods in order. Technician B loosens the head bolts in random order. Who is correct?

An interference engine has enough clearance between the pistons and valves so that it will not bend the valves if the timing belt breaks, slips, or skips.

Technician A unbolts the A/C compressor from its bracket and repositions it so that the engine can be removed without disconnecting the A/C hoses. Technician B captures the refrigerant using a reclaimer/recycling machine before removing A/C hoses from the compressor, then plugs the lines and connections at the compressor. Who is correct?

Describe how a pressure test is done.

A major advantage of cleaning ovens is that they are a more environmentally acceptable process than chemical cleaning.

The first step in disassembly of an engine is usually the removal of the ____________________ and ____________________ manifolds.

Technician A says it is a good practice to clean the engine and engine compartment before beginning to remove the engine. Technician B says all engine fluids should be drained before engine removal. Who is correct?

While discussing cleaning engine parts, Technician A says a parts tumbler is good for cleaning aluminum components such as intake manifolds and cylinder heads. Technician B says that the cleaning method used depends on the component to be cleaned and the type of cleaning equipment available. Who is correct?

Water-soluble soils contain petroleum by-products derived from crude oil including tar, road oil, engine oil, gasoline, diesel fuel, grease, and engine oil additives.

____________________ should be used to prevent damage to body work and painted surfaces around the hood opening.

Technician A leaves the drive axles attached to the wheel hubs, disconnects the inboard CV joints at the axle flange, then positions the axles so that they don't interfere with engine/transaxle removal. Technician B separates the lower ball joint from the steering knuckle then removes the drive axle from the vehicle. Who is correct?

The flywheel for a vehicle with a manual transmission should be examined for damage and signs of ____________________ problems.

List the procedure for keeping the customer's vehicle clean while the engine is being rebuilt.

A ____________________ hammer is used to drive the CV joint spline out of the wheel hub.

An engine that has enough clearance between the pistons and valves so that if the timing belt breaks the valves will not is called a(n)____________________ engine.
