Review on 💨 Dorman 800-403 HVAC Heater Hose Connector - Ideal for Compatible Model Selections, Enhancing SEO by Keegan Herbert

Easy to install, be careful when removing and reinstalling the old ones, do not damage the plastic T on which it is mounted. And it helps to lubricate the inside a bit with the new coolant that drips when you take the old one off before attaching it. it's a tight fit. Many of the plastic parts in my 2002 Yukon XL's cooling and heating system became brittle and I was very surprised that I broke nothing but the old quick coupler. The old/original design pulls into the hose much tighter (it's impossible to pull it out so I had to cut the hose off) so I fitted a 1" hose clamp to prevent possible leakage.
