Each CorkSport Reservoir is laser cut from 11-gauge Aluminum, then TIG welded for the best appearance and strength. The tank is then Powercoated Wrinkle-black for the cleanest finish.

Once the tanks are assembled and fully welded, we pressure test every tank to ensure there are no leaks!

The aluminum reservoir will be hot after normal engine operation.

Really, this ought be called the "Leave Me Alone, Raider. HERE IT IS!" Coolant Reservoir. I ain't made tho. 100% must have to replace the OEM plastic that shatters after a few years.

My tank arrived well packaged with all the ports wrapped up and protected nicely. I even got a free little snack, sticker and a little drawing from one of the guys who put my order together!

The part itself is extremely nice and well built. You can tell the level of craftsmanship that went into the part by the welds and machining of the pieces on it. The black paint brings it all together for a very classy look.

The install was extremely easy. You just need to drain a little coolant and swap out the tank and refill it. Everything fit extremely well and looks very good. Night and day difference from the original oem tank.
