87 Iroc Radiator Cap Question - getting hot - Third Generation F-Body Message Boards

anomolee · 09-30-2009, 05:58 PM

Hi All,
My 87 Iroc 305 tpi has been having quite a bit of work done on the injection, mostly my fuel regulator. I've developed a situation where it's running a little warm. When I stop if I hit the radiator cap a few times it will release water into the overflow quickly.
Do you think my cap is bad, causing the quick release of water and making the car run warm?
Thanks for the help

considering the price and avaliability of a rad cap i say might as well pick one up.

caps job is to keep pressure on the system, since pressure raises the boiling point of the fluid.

that reminds me of that joke.
Patient: Doctor, it hurts when I do this.
Doctor: Well, don't do that!

lol
seriously, do what the other guy said. replace the cap, preferably one with a pressure release lever.

Fixed. I guess it was the cap.
