cylinder compression test tutorial will work for any vehicle. check your recommended compression ratios prior to testing for your vehicle. I didn't do the 10 second rule for the video due to already passing the compression test prior. video is instructional purposes only. my vehicle in video is a 2006 cobalt ss lsj which should read aroun 205 to 210psi from factory. All four cylinders came back around 205 psi. When doing your reading take into account your vehicles milege parts get worn down over time an compression will drop does not mean that your engine is bad it's normal over time. in the video the cylinders at the top aren't in order. start with cylinder one an make your way over to the last cylinder typically on a fwd 4 cylinder like above cylinder one starts on the passanger side
