2001 Oldsmobile Silhouette Questions & Answers
Where is the EGR valve located on 2001 Oldsmobile Silhouette?
The EGR is mounted to the intake manifold--look in the right rear area behind the throttle body mechanism. There are two 10mm nuts, as well as a 10mm clamp screw holding it down. Remove the clamp screw first, then remove the two 10 mm nuts. You should first remove the intake air hose between the air filter and the throttle body, then remove the two front engine mounts, then using a ratchet strap, pull the top of the engine forward until it contacts the radiator fans. This will give enough room the reach the EGR valve and the exhaust pipe beneath it.
Headlamps not working.
is the light setup one ballast for high and low beam ? if so the ballast has gone, probably even the bulbs. replace the ballast and bulbs. some aftermarket ballasts don't last, if you cannot find the right ballast for replacement you will need to replace both ballasts. as every ballast set are set the same and sold in pairs.
