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

Perfect fit, super easy to install

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!

WORKS GREAT

I have a 2013 GMC Yukon XL and this fit with no issues. It is a little different than the OEM part, but that did not affect its performance. I did have to readjust it in its spot after a couple of days because it was a little loose and started a vibrating noise in the cab. Make sure the clip sits in the slat on the inner wall.

Had to replace old reservoir on 2013 GMC Sierra SLE as it was leaking. Super easy installation, maybe 20 minutes in total. This reservoir was a perfect fit, hoses went on with no issues. Reservoir has no leaks now and truck runs much better!

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.

It's exactly the same as my old coolant tank from my 2011 Silverado extended cab truck, and it worked for me.

Perfect match for my 2013 Silverado

This item worked well but be prepared to get a new hose clamp for the install. I could not reuse the stock GM hose clamps without it leaking slightly. Whether the sizing on the coolant ports is slightly smaller or the clamps were just weaker, I don’t know.

Funcionó correctamente 5 meses, después empezó a fallar y fugar por el orificio que se encuentra en la zona del tapón que sirve para dirigir el sobre flujo al drenaje inferior, pensé que era el tapón, se probó con uno marca Dorman y uno Motorad, ambos nuevos y de 15 psi y continuaba perdiendo refrigerante.

Exactly as described and what I needed, always trusted Dorman products.

arrived in brand new condition and exactly on time
