Great if you need 15psi
Great! Needed 15psi instead of what came on the repop expansion tank- works great!

OEM
Perfect fit for my 2015 Chevy Silverado 1500 with 5.3 V8. I replaced the cap because the plastic over flow resovoir tank was leaking so I had to replace the tank. The new OEM tank did not include the cap so I figured I would replace thecap with an OEM cap too.

OEM Quality For a Great Price
Bought this to replace the one on my 2018 Chevy Tahoe LT due to seepage. This is of the same quality as the OEM and it’s a great price. I would recommend buying it instead of the OEM.
