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

Revainrating 5 out of 5

This fixed my phantom radiator leak

I was having trouble with my 2002 Gmc Sierra 1500 SLE with a 4.8L V8 that was losing coolant. I thought I might have a very small leak in the fitting which could be incredibly frustrating. I had to fill up the tank every three months, so I decided to play this cap cheaply. I'm happy to say that was a year ago and I haven't had to fill up my tank since.
