Dorman 603-054 Front Pressurized Coolant Reservoir with Cap Compatible with Select Cadillac / Chevrolet / GMC Models

Perfect fit for my wife's 2011 GMC Yukon Denali with the 6.2L V8. Installed during a radiator swap and could not be happier with the quality!

It working just fine. Fit in the spot. It was the right one I needed

Cant be told from original. Watch the vids. Pressure tested and thoroughly inspected. As good as or better than OEM at a fraction of the cost. Don't settle for less than Dorman when buying aftermarket. A quality product with an exact fit is worth a buck or two extra.

Fit and worked great almost OEM quality couple months on my yukon

perfect fit works great

Solid piece, works fine. No leaks.

This is way more heavy duty than the factory equipment. The overflow "tube" terminates as a rectangle. Which is no big deal at all. But, if they had made it a circle I could have added a short tube to better direct any overflow better.That said, I strongly recommend this to anyone. On the 2011 GMC Sierra 1500 5.3l you will have to drill a hole in the front support leg. The leg/tab is see-through so mark the original hole, drill it and reuse your original factory screw. The tab is pretty big and in no way will this weaken anything.
