I just lost a post, and I have a final in a few hours that I really need to cram for. But is it blue, said coolant cap? Check Duralast 7049. Same as my wife's Porsche 4.8L NA, (probably a lot of VWs to be honest)..

Thank you.

Smoke that final.
I'm not going to wish you good luck because you don't need any.
