Basic part, HUGE difference.

Had an overheating issue with my Camaro. Looked online, and the suggestion was to replace the Rad cap. Went to a national retailer, and bought a after market cap. Fitment was loose, and issue was not solved. Went to the dealer, didnt have an AC Delco cap in stock, and was $$$$, and was 3-5 days out. Checked 1a, in stock, cheap as hell, and had it in 2 days! (and didnt pay for express shipping). Problem solved!

Works good I hope you can start including it with the radiator because stick caps dont work on your radiators but together they work great
