Hi there! thanks for the reply. I had searched through the GM parts websites and also checked with my local part stores...they all only stocks the whole reservoir...they don't sell the cap seperately

It broke/cracked on it's own, due to the heat i reckon. I will spend some some scouring the forum for answers..
