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.

Billet cap

Shipping was faster than expected but slight fitment issue (to tight) but with a little bit of sanding was able to get it on

Mr. Leon king SUPERB customer service

A little glitch got fixed up better then I thought it would. And this during these extra hard pandemic times for business etc. It may be considered by some as a small fix. But with even more problems in my life besides what the pandemic brought to it. This experience gave me a POSITIVE I needed alot. Would buy again if you have what I need/want. I published Feedback on all the CHEVY SONIC involved websites about 9 or so.
