Engine Compression Test
A cylinder compression test is one of the most accurate methods in determining the condition of internal engine
components.
Always perform the compression test with a fully charged battery. Engine should rotate at least 300 RPM.
1. Remove both ignition coil packs from the valve cover.
Remove both spark plugs.
2. Remove both fuel injector harness connectors.
3. Install the compression gauge into one of the
cylinders.
4. Insert the lanyard and push the starter button for no
more than 15 seconds. Obtain reading from gauge,
then release gauge pressure.
5. Measure remaining cylinder.
6. Reassemble in reverse order. Tighten fasteners to
specification.
