Review on ACDelco RC98 15 P.S.I. Radiator Surge Tank Cap - GM Original Equipment by Paul Lee

Revainrating 5 out of 5

Simple Coolant Leak Fix

Like a few other reviewers, I had an unexplained coolant leak on my 2005 Cadillac SRX with no visible leaks. Some research has shown this to be a common problem on GM vehicles where the o-rings in the stock radiator cap wear out and coolant leaks from the overflow vent tube. I replaced the cap, it seems to be OEM ACdelco, the problem is solved.
