Question about GM Heater Hose fitting

Recently one or both of my heater hoses started leaking. In attempting to replace them, I noticed some strange fittings at the ends of the metal tubes the hoses connect to. When removing the spring clamp, the tip of one of them actually cracked off and broke.

I'd like to know what the purpose of these fittings is? How do you get them off since I'll need to replace one of them? Why doesn't the hose just connect directly to the metal tubes as they have on older cars I've owned?

Here is a cell phone picture of what I'm talking about.

Easy to get. Their are two different sizes. Any real auto parts should stock them. one end is a quick disconnect and the other end should be threaded if I recall correctly.

I wasnt able to distinguish from your photo exactly what you were talking about. I can see some very standard spring clamps that hold the hoses tight.

I also see what looks like a valve that is sometimes used to stop or allow flow through the heater core.

Whatever it is, take it down to your FLAPS (friendly local auto parts store) and they should be able to identify it. If it is something too wierd, it might be a dealer only item..

The silver thing right smack dab in the center of the phtoto. By squeezing those white plastic pieces I'm still not able to get this off. I'm going to go by my "FLAPS" and see if I can buy the replacements and take a good look at it.

That helps a lot... Note... these old heater hoses can get to be tough as heck. They resist pulling off. Sometimes it is better to use a sharp knife and cut the mothers.

It does indeed, but in my case the "quick release" is connected to a metal tube that makes its way around the engine. There is no way to cut it off. The plastic "snout" that connects to the hose that goes to the heater core broke off easily, and for this reason I believe this was cracked and leaking.

If I get this sucker off, I'll try to get photos.

Ok, these so called "quick release" things are really getting to me. Even with a set of quick release tools from Autozone I could not get it off. After spending way too much time on this, I finally got out the Dremel with the cutting bit and cut the sucker off. I was able to buy two new ones at a dealership, but I wonder if I wouldn't be better off clamping the hose right on the metal bar.

The only reason I can think as to why anyone would put these on a car is to possibly avoid having to cut off an old hose. If this is so, then this is another example of where the solution is worse than dealing with the original problem.

The purpose of these fittings is for GM to get your car out of the factory the cheapest and fastest way possible and to make it as idiot- proof as possible on the assembly line. If the fittings lasted past the warranty period, GM is happy.

Unfortunately true, and the warranty period for things like this can be pretty darn short.

T'wood still have been easier to avoid the cost of these ridiculous beasts and just clamp the hose to the metal line. Plain and simple!

I just drove a 2004 Buick that DOES NOT have these and just has simple hose to pipe connections. GO FIGURE! I hope GM is done with the stupidity!!!
