This is a DIY video on how to repair the heater hose and replace the auxiliary heater inlet hose tee connector on my wife 2009 GMC Yukon SLT 2wd 5.3l Flex. The heater hose fitting was completely broken and leaking coolant. We also chose to replace the tee connector while performing the repair. It was an inexpensive part and could have been brittle lithe the hose connector.

It's Sunday here and all the Chevy dealerships and garages are closed would I be able to replace the tee with a tee from drip hose or a piece of CPVC?
Thanks to Jay Cooke at Volunteer Garage this video came out great!
