Measuring The Engine Compression Pressure; Starter, Generator; Inspecting The Radiator Cap - Isuzu 4LE2 Owner's Manual

Measuring the Engine Compression Pressure

This should be performed at periodic inspections or when the engine output has
dropped.
ADVICE
• When the compression pressure is below 2.5 MPa (26 kgf/cm²/363 psi), have
the defective parts of the engine repaired.
In accordance with the periodic inspection and maintenance list, clean the
commutator of the starter, and check the wear and contact surface conditions of the
brush.
Check the operating pressure of the radiator cap pressure valve using the radiator
compression tester. As for the operating pressure of the pressure valve and the
inspection period, follow the provisions specified by the machine manufacturer.
