How to Check Cylinder Compression

Model: Ford Mondeo / Fusion MK 1 - Years 1993-2000
Part: Engine

This video explains how to check the cylinder compression on a Ford Mondeo. First, remove the ignition coils by disconnecting the connectors and unscrewing the 10 mm bolt that holds each coil. Now, remove the spark plugs using the appropriate socket, checking that they are not wet or worn. Next, screw the pressure gauge onto the first cylinder; get in the car, press the clutch and accelerator fully, and start the engine, holding it for five seconds. Read the value indicated by the gauge and note it down, then release the pressure using the relief valve and screw it into the second cylinder to repeat the test; repeat the process for the other cylinders.
