I was having problems with brown gunk getting under radiator cap and the fluid wouldn't stay to the top of the filler tube. Replaced the venting cap I had on there with this cap that is recommended for Pontiac Grand Prix and it fixed my problem. No more brown gunk and the fluid is right to the top and is clear.

After this radiator cap was used to replace an aftermarket radiator cap on my 2000 Gran Prix GTP, the stability of the engine operating temperature improved considerably.

Wouldn't fit, Sent a plastic covered version, not as pictured. No matter how hard you push down and turn, it won't clamp both sides. No spring inter-action when push down....Shorter end to cap.
