How Do You Perform A Compression Test On The Engine In A Nissan Pathfinder?
Performing a compression test on the engine in a Nissan Pathfinder is a simple way to diagnose engine trouble. When parts wear out, such as cylinder walls, piston rings and valves, the SUV loses power, burns oil or runs poorly. Tearing the engine apart to see what is happening inside is a difficult, time-consuming job, but a compression test is a quick and easy alternative. Prepare by warming up the engine in the Nissan Pathfinder. The battery must be in good condition since it is required to rotate the engine several times during the test. Turn off the engine in the SUV once it is sufficiently warm, since running a compression test on a cold engine will give inaccurate results. Disable the ignition system to avoid electrical shock during the compression test and remove all of the spark plugs. If the Nissan Pathfinder contains a V6 engine, there will be six spark plugs. Some 2008 models contain a V8 engine with eight spark plugs, so be sure to remove all of them. Insert the compression
