Billet Coolant Reservoir Cap

Dress up your engine bay with our new billet coolant reservoir cap. This billet cap fits over your existing coolant reservoir cap to give your engine bay that extra shine. The cap will be a very snug fit so you can still use the cap per normal and not have to worry about it slipping off. Available in 3 different sticker styles or without a sticker so you can add your own personal touch. 

COLOR NOTE: The color you select determines the color of the ZZP logo, not the color of the sticker. Please choose carefully. Also available with no sticker. 

Fits: 2016-2021 Chevy Camaro, 2013-2019 Cadillac ATS (2.0, 3.6, and V models), 2012-2020 Chevy Sonic, and many more. This cap is intended for (and should fit all models with) GM coolant reservoirs that use the newer 20psi cap, not the old 15psi style.

Clean appearance

Needed to dremel out my stock one but got it on nice and snug. Really cleans up that basic coolant tank

Good cap. Simple. Looks Good.

It is as described. It seems like good quality. The logo is separate, which is good as that way you can fit the cap on and decide how you want the logo to look when it is tightened on.

Looks good

It slips over the factory cap. A little piece of double sided tape would have been a nice addition. Looks great though along with the oil cap
