Hey
i need to know all the specs on how to change the EGR valve in my chevrolet cavalier 2.2 z24. Where its located on the engine and the specs on how to replace it. If there is any torque specs for the bolts or anything if you happen to have a diagram it would be helpful as well
anything else you need to know to help let me know.

It's pretty much unhook electrical and vacuum if any unbolt and remove. We have no torque specs for the bolts, just don't tighten them like a gorilla, about 15 ft lbs would be about enough. Make sure the egr passages are not clogged in both directions. We have no pics of that.

If it's a 3.1L then it's by the throttle body on rear of engine. It wil be a round looking thing with an electrical connector at top it may have a wrinkled like pipe going to it on the bottom if it's a 2.4L or 2.2. Lit doesn't have one
