Re: cooling system ?s
pulled the plugs and seem ok , no leaks any where i can see , i did change pressure caps and it did seem to suck down the overflow a little . wondering if the pressure cap could cause it not to suck out of the overflow >?anyone here of this ?

Re: cooling system ?s
You need to use a pressure tester on it with the engine off - much easier to find leaks that way.

Re: cooling system ?s
i got this dye test from napa and it turned out negative . put a new radiator cap on her and phew she is back to normal. didnt know the cap could cause that.
