Low pressure radiator caps?
 

Hey guys...anybody know where I could get a low pressure radiator cap to use on my FD with Evans coolant? I've been using a zero pressure cap (by just removing the rubber seal from the stock cap), but I now am thinking that I want a low pressure cap for use instead.

Any suggestions are greaty appreciated...thanks!

Im almost positive that pineapple racing sells the 7psi caps.

You can get a 7 psi cap at any auto parts store...about $5.

Thanks for the info guys! I'll check out the local Kragen tonight.

What's your rationale for going low pressure over no pressure? just curious...

Well...the main thing for me is that I realized that tracing leaks and whatnot are nearly impossible in a zero-pressure system since in a hi-pressure system, leaks will start to flow out fairly noticably once the pressure builds up. I've had a mysterious loss of coolant the last week or so, and I just want to track down any obvious leaks.

Thanks

I dunno about that, when I had a coolant leak in my car at 0 PSI it was still pretty easy to find. try a pressure tester that attaches to the top of the filler neck and just pump it up.

Yeah I was thinking I'd do that as well. Right now, I'm dreading the fact that it *might* be a coolant o-ring failure, which would really suck since the motor was rebuilt like 20k ago.
