Question

technician a says that a cylinder leakage tester can help diagnose an engine mechanical fault. technician b says that a compression tester can help determine an engine mechanical fault. who is correct? select one: a. technician a b. technician b c. both a and b d. neither a nor b

Explanation:

A cylinder leakage tester checks for leakage in the cylinder, which can indicate mechanical faults like bad piston rings or valves. A compression tester measures the compression in the cylinder. Low compression can be due to mechanical issues such as worn - out piston rings, damaged valves, or a blown head gasket. So both testers are used to diagnose engine mechanical faults.

Answer:

C. Both A and B
