Radiator caps

[Bob Reynolds]

Has anyone used a CST radiator cap on an lt1? I bought one today from Auto Zone here in Garland. It's an 18psi unit as per Chevrolet. Just wanted to know if anyone has used and or had any problems with them.

When I suspected my radiator cap had gone south, I bought one of those and it worked fine. Ultimately it wasn't my cap, so I put the stocker back on and saved this for a spare. No difference in any performance of the cooling system.
