GM Plastic Heater Hose T-Fitting(s) Broke!
It's not if, it's when. Well it happen to my 07 GMC Yukon(152k miles) while driving on a local hwy about 8 miles from home. By the time I got it pulled over(2 min) to a suitable place the engine was getting mighty HOT. With the help of a local neighbor & friend, I patched it up good enough to drive it home where I did a proper repair.
I installed a pair of GruvenParts.com billet aluminum GM heater core tees, silicone hoses, & worm clamps. What a PIA.
While I was at it I also replaced the 2 into1 heat hose with Y-fitting with a Dorman 626-553 that has a metal Y in it. Most replacements have a plastic Y. NAPA also sells it under pt# 827-5730-1. Also, replaced w/new many other coolant hoses, coolant, and water pump.
I hope this helps.
