Product Questions & Answers

Q:Will a 138 Ka 20psi  radiator cap fit 3.6 2010 camaro?
Robert C.
A:BEST ANSWERHi Robert, I'm glad to assist you. The radiator cap you mentioned, labeled as "138Ka" and rated for 20 psi, may work for a 2010 Chevy Camaro with a 3.6L engine. Radiator caps are designed to meet specific pressure ratings and fitment range requirements for each vehicle's cooling system. You can check the details on your vehicle's owner's manual to confirm it as well. I hope that answers your curiosity. Show less

Q:how do i open when cold 2010 gmc 1500 radiator cap on radiator ?
MARK F.
A:BEST ANSWERHi Mark, I'm pleased to assist you. It is acceptable to remove the radiator cap when it is cold, but not when it is hot. You can use gloves or a large heavy cloth to protect yourself. Turn the radiator cap counterclockwise, without pushing down, to the first stop. This allows any remaining pressure in the cooling system to be released. After the pressure is released, push down on the cap and turn it until it comes off. Click on the link below to order at 62% off the regular price today while supplies last. I hope this is helpful.
