can somebody tell me what information i should know when purchasing a radiator cap for my 92 Z28. what are the dimensions? 2 and 1/4? Any info would be greatly appreciated.

 

common somebody tell me!

 

They're pretty much all the same

kind of a universal part

just look on the cap to find the holding pressure it's probably between 7 and 14 lbs then go to the store and buy a new one

 

Hey Alex, gm has some pretty decent looking rad caps, even with updated safety junk on it. Just snag one from there, its a stock rad cap you got anyways lol...

I remember since I was the one that had to tighten the damn thing lol

 

hehe

don't call me gay or anything but the reason i'm asking is because i want to buy this cool blue looking "BLITZ" radiator cap. but seeing as how they make parts for supras, i would think something would be different in the dimensions....

 

i think there all pretty much the same, i run a 10 or 11 lbs with the red tab..works good, i dont know what it does diff, but it was like 2 dollars, oh ya, my radiator had a leak with the 16lbs of pressure so i down graded, why are u buyin a new one?

 

buying a new one because my old one is ****ed up lol. just ask slade, it took us an hour just to screw it on properly lol

 

Well I admit your rad cap was a bit tighter than normal, but I would blame that on the new rad.

The cap I would replace out of functionality, the newer GM caps are better designed to handle pressure a bit differently and a new cap will always work better than a 10 year old one.

 

Summit has a nice polished Aluminum one from CSI I think. The price wasnt to bad either. Much cheaper than the Be cool ones. But look just as good.
