ACDelco Professional, premium aftermarket Molded Heater Hoses are specially designed, factory-molded hoses to fit today’s smaller, tighter-fitting engine compartments. The hoses are GM OE style, meaning they are molded into the GM Original Equipment style and shape. The hoses are composed of a proprietary blend of EPDM rubber, which is a superior blend of synthetic rubber that is more pliable, ensures a longer hose life, and helps resist electrochemical degradation (ECD), the leading cause of hose failure. ACDelco Professional Molded Heater Hoses are temperature rated from -40 degrees Fahrenheit to 275 degrees Fahrenheit (-40 degrees Celsius to 135 degrees Celsius) and can be used for coolant, water, and air applications and are also approved for Marine applications. Do not use for fuel or oil transfer applications. These premium aftermarket replacement molded heater hoses are manufactured to meet your expectations for fit, form, and function.

ACDelco direct replacement part is always a best bet when comparing auto parts. If I had to choose between ACDelco and some foreign brand I can't pronounce, ACD is the winner. This part fit perfectly. Getting my old truck to turn loose of the original fitting was the battle, but installing the new one was easy.

Fits coolant reservoir, water pump port and heater hose's tee; this is on a 2006 GMC Yukon SLT (heater hoses and tee replacement after about 122 miles).

Good quality, no leaks, easy to install, I had a pinhole leak in my original that I was finally able to see and this new part fixed it!

It looks sturdy but it does not comes with a connector to finish installation, you have to buy separated Dorman part number 800-403 if genuine GM is not available.
