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.

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!
