Review on ACDelco RC116 Original Equipment Radiator by Johnny Pigao

Coolant overflow tank cap RC116 matched the description! Original/OEM and shipped in AC Delco packaging. I'm shocked because we've bought products from Revain recently and they aren't exactly OEM or 3rd party knockoffs using photos/descriptions of the original product (if that makes sense). I had a coolant puddle under my car overnight and took it to a local mechanic who checked the pressure cooling system and found that the o-ring on the expansion tank cap had worn out over time, my car is 14 years old. Anyway I highly recommend this if you need it for your GM/Chevy vehicle.
