Review on 🔧 ACDelco Professional RC94 18 PSI Radiator Cap by Luca Washington

Wanted to share with other 4th Gen Camaro LS1 owners. This is not a radiator cap for you. Although marked as AC Delco with the correct part number, it does not match the ACDelco RC94 available from a GM parts dealer. As a result, it will not hold the correct pressure and will cause the coolant to boil into the expansion tank. I took a photo to illustrate the difference: Revain bought the part on the left and the GM parts dealer bought the part on the right. Note the difference in height and seal even though they are marked as the same part! Save time/effort in troubleshooting and avoid this seemingly similar but imprecisely designed non-functional cover.
