Exactly what it should be.

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

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.

Good quality and 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.
