quick disconnect for heater hose?

[Archtoker420]

Hey guys I have this part leaking coolant I think it's a quick disconnect. Can any one help me or give me any advice? It looks like this..

I just bought a new one to replace mine. Some guys remove them and you can get a brass threaded nipple that will fit in there. You then have to cut the hose and use a hose clamp to attach to the nipple. Not sure of the thread size though.

I was told that too. But at the moment only had enough cash for a replacement. I've heard of them snapping off too. I'm about to do mine so I'm hoping for the best.

Either way you'll have to unscrew the fitting from the intake. I've had a lot of persistent leaks with the quick disconnects in the Suburban and other GM vehicles. Replacing it with a brass nipple for the heater hose is a good option. Take the old fitting to the parts store and match the threads up.

Most of the threads on the fitting & in the intake manifold are 1/2" male or female tapered pipe thread. On our Yukon the "quick-connect" broke off even with the manifold & I tried all of the different styles of "ease-outs" that I have & none of them would remove it! So... I measured the hole in what was left of the quick-connect fitting, drilled it slightly & re-threaded it 3/8" female tapered pipe thread! I used a brass adapter that was 3/8" MPT X 1/2" FPT & screwed it in using liquid pipe thread sealer on the threads. Once it was almost bottomed, then I put sealer on the new quick-connect fitting & proceeded to carefully screw it into the brass adapter! The bass adapter finally bottomed out against the intake manifold & the quick connect made it about another turn before it was very snug! Put the hose's tube in with the new seal & though it felt a bit loose, it does not leak!

Some of these fittings come out easy and some break off which can be a huge pain in the ass. I replaced my a couple of years ago. Looked about like yours in the pictures. An old mechanic friend of mine suggested to get the engine pretty warm before attempting to remove the fitting. I followed his advice and mine came out easy. I replaced it with a barb fitting and a couple feet of new heater hose. Easy fix. I was lucky. I hate those quick connect fittings!
