PCV VALVE Where is the location for the PCV valve on a 2006 Grand Prix? 78,000 miles on car Car also has original Dex Cool. Can it go 100,000 miles without changing?

the last one I did was on the passenger side on top of the intake. it was covered with a flat plate that was held in place with 2 bolts I think. remove the plate and the PCV is under the cover. pull out valve there is a spring between the cover and the valve, make sure it is put back in place when re-assembling. it does not use a hose to control crankcase pressures.

look on the car bonnet

Click here to see.Here's another.Here's the pcv valve.

check the pcv valve, it will **** up oil and burn it if bad, and also check the hose to pcv valve. depending on vehicle the price for a pcv valve is very reasonable. pull out pcv valve and shake it ! if it rattles its ok. but if not replace it. have a good day !! ( positive crankcase ventilation ).

Your car was likely manufactured with GM DEX-COOL coolant. If it has been changed to universal you may use any universal coolant.

If the coolant in the coolant reserve tank is orange you should use genuine DEX-COOL which should be able to get from your local auto parts supplier.

All the best.

I just replaced mine and had the same problem. If you look at the new one, you should find a small hole at the base of the metal tube. Using a mirror, I located the same hole in the one in the valve cover and inserted a pointed awl into it and was able to pry it out. Do it slowly since you are prying against plastic. When inserting the new one, I found that it should not be inserted as far the original one was and has a gentle snap.

If I remember correctly this vehicle has a plastic plenum and the pcv valve is inside the plenum. Only time it is usually replaced is when the intake gasket needs replaced (and it will).

pcv valve on a 3.1 L is located in the front valve cover on top of engine. Hope this helps

Are you sure you got all the air out of the cooling system? Air pockets are very common problem when you do any work to the cooling system. An air pocket will do what you discribe.

You might have a thermostat stuck open this will not allow the coolant to reach correct operating temperature.
