Engine Repair ToolsEngine Repair Tools

• Compression testers– Used to read the amount

of compression pressure developed in the cylinders.

continued…



• Cylinder leakage tester– Used to indicate

the amount of pressure leakage from the cylinder and combustion chamber.

continued…



• Oil pressure gauge– Used to read and diagnose engine oil

pressure.

• Stethoscope– Used to listen for engine and component

noise.

continued…



• Engine Supports– Used to hold the engine in place while a

transaxle is removed from a front wheel drive vehicle.

continued…



• Piston service tools– A ring compressor is

used to hold the rings inward in the piston ring grooves for piston installation.

– A ring expander is used to expand the ring for installation on the piston.

– A ring groove cleaner is used to clean carbon from the piston ring groove.

continued…



continued…

• Cylinder service tools– A deglazer is used on glazed cylinders to

restore the proper surface finish.– A hone is used to sand the cylinder walls

to correct minor bore imperfections.– A ridge reamer can be used to remove the

ridge of unworn cylinder material from the top of the cylinder bore.



• Valve train service tools– Valve and seat resurfacing equipment– Valve guide repair tools– Valve spring compressor– Valve spring tester

• Cam bearing tools

• V-Blocks

continued…



• Torque Angle Gauge– A torque angle

gauge is used when performing the torque-turn method of tightening fasteners.

continued…



• Oil priming tool– Used to circulate engine

oil throughout a new or rebuilt engine prior to its initial start-up.

continued…



• Cooling system service tools– A pressure tester is used to pressurize the

cooling system to help locate internal and external coolant leaks.

continued…



• Cooling system service tools– Hydrometers and

refractometers are used to test the strength of the coolant (freeze protection).

continued…



• Cooling system service tools– Coolant recovery and

recycling equipment is used to drain, recycle, fill, flush and pressure test a cooling system.
