Question about Pontiac Grand Prix
Easy enough to do.
Make sure you get a gasket with a new egr valve.
CLEAN off the old gasket from the engine real good,may have to scrape it off.
Don't let anything fall into the opening,maybe use a paper towel in the opening to keep crud out.
Use some penetrating fluid on the nuts/bolts to help loosen them BEFORE trying to remove,you don't want to snap one off!
Make sure the hole is FULLY open,those cars tend to get the egr system clogged so if ya have a shop vac use it to **** up any crud from the hole.
Place gasket back onto the engine/egr valve and tightem the bolts up snug,ya don't want to crank them down so tight they snap off,just get it all nice and tight/snug.
Don't forget to hook up any hoses from the egr valve!
Start car,test drive.
My old '84 egr system was clogged up badly,so they cleaned the entire system along with cleaning up the throttle body(carb)and installing a new pre-heat assy for the throttle body,she ran smooth after that.
It had about 86,000 miles on it from old owner,i sold it then the oil pump went out on the other owner,those cars can have weak oil pumps so watch your gauges!
