Product ReviewsRadiator Cap-VIN: B, Eng Code: LC8 ACDelco GM Original Equipment RC85

OE cap for my 2002 Trailblazer - no more seepage - Perfect!

This cap fixed the coolant seepage that was happening around the top of the neck under the old cap. The old cap's O-rings were squished flat after 14 years, not sealing tight. This should stop any air getting pulled back into the system at cool down, which is bad with Dexcool or any coolant. Don't risk having a cooling system failure due air getting into the coolant and whipping up a gooey mess, all because of a <$10 radiator cap!

Note: Be sure to clean out the inside of the radiator fill neck to get out any old crud first that might make a sealing problem, before installing your new cap.Read full review...

GM RC85 radiator cap

I had noticed a very small leak of antifreeze from the cap. First I thought it was the top radiator hose but taking a closer look & inspection... I was shocked it was from the cap. I looked up reviews for 2005 GMC Envoy leaking from the cap & sure enough it is a common thing with age of an old cap.. I'm completely 100% happy with this new cap. No more leaks & awesome price!!!Read full review...

OEM quality

The o-ring on my original cap was the cause of a coolant leak.
This new cap fits perfect and remedied my problem.
