Compression Check

2013 Chevrolet Tahoe 4WD V8-6.0L HybridSECTION Compression Check




The minimum compression in any 1 cylinder should not be less than 70 percent of the highest cylinder. For example, if the highest pressure in any 1 cylinder is 862 kPa (125 psi), the lowest allowable pressure for any other cylinder would be 607 kPa (88 psi). (862 kPa x 70% = 607 kPa) (125 psi x 70% = 88 psi).
