Fit same as original with same 20 psi cap
for 2012 gmc sierra 1500 - fit same as original with same 20 psi cap, is same Dorman pt no. at auto part stores for $58-$72, shipped 2 days, received on time, recomend it. Easy to install if lift air filter box up, ratchet can fit under tank for rear nut if you dont have long extension, just remove and install 2 hoses, and 2-10 mm nut and screw, no leaks after driving and checking.

Perfect fit for a 2011 GMC Yukon Denali
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 well
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.

Fuga por el tapón después de 5 meses
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.
