huh? you need to be a little more specific. You mean your coolant is leaking all over the floor? Have you checked under the car to see where the coolant is coming from? radiator? cap? hoses?

Likely coming from the coolant overflow tank on the passenger side of the car. Replace your pressure cap that goes to the overflow tank(this will either be on your AST or on your water filler neck if you have the AST deleted). This may fix the problem. If that doesnt fix the problem, replace the hose going to the overflow tank. If that doesnt fix the problem, hope you dont have a blown coolant seal.

When I first got my 93, it did this after a long road trip. Turned out to be the pressure cap.

check your pressure caps from the filler neck & ast, i had the same problem and it turned out tri-point gaved me the wrong cap (non spring) for the ast i bought from them.

i dont think the filler neck uses a spring cap only the ast, im not by my car right now so i cant check

djseven Apr 24, 2009 04:15 PM

So you didnt replace them? Only the cap on the AST should be a pressure cap(spring). Replace them and see if that fixes the issue. Just looking at them and saying they are fine will not cure anything.

im actually going 2 do it 2 morrow im also going 2 drain my fluid you think thats a good idea

I used to have the same problem. I replaced my rad cap but it was still happening. When I was installing my Fighters Garage AST, I was taking the lines off the stock AST and one of the nipples broke off completely. It was rotted clean through. After installing the replacement AST, I have not had any more coolant spilling out. Replace your rad cap (regardless of how it looks), if your still having problems, check ALL your coolant lines and any other places that could be leaking(water pump, t-stat housing etc.). Failing that I would start looking at your coolant seals..... You could also do the champange test to to help confirm this.
