Measurement Procedure
WARNING: This page is about a different variant/trim than selected.
- Measure the tension of the valve spring using the GE-22738-B tester. Refer to Engine Mechanical Specifications .
- If low valve spring load is found, replace the valve springs. DO NOT use shims to increase spring load. The use of shims can cause the valve spring to bottom out before the camshaft lobe is at peak lift.
