This part worked fine for about 2 months and then it gave out, showering antifreeze all over the inside of my hood, fenders and motor. What a mess.

The white plastic piece does not handle the heat well and gets soft and deforms. It did not last even a 3 months before failing.

I will now try the more expensive one in the hopes that the black plastic on that one is of sufficient quality to last a few years at least.

Don't throw your money away on this one unless you are in a bind and have no choice and are aware its a temporary fix and that it will fail and leaved you with a mess and overheated vehicle soon enough.

                  Hi, I researched and found that this heater hose connector would not be an ideal fit for Gm 7.4L engine. However, for assisting you further on locating the exact heater hose connector please provide the year, make, model and engine size of the vehicle.

              • Q:

                I just installed this connector and the retainer clip broke when inserting the heater hose end. now it will not stay in, very loose and leaking coolant. Is there a specific trick to getting the tube to fit in snug and create a seal?

                  I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.

                • A:

                  Yeah, it is not a good fit and the white plastic does not hold up for very long either. Just the weight of the hose itself is enough to cause it to fail. Either try the more expensive part with the black plastic (don't know for a fact if its any better but the original was black plastic) or switch to a nipple.

                  Some GM fittings have a flow restrictor to prevent gurgling and cavitation damage to the heater core (not sure if this one does or not) so you might want to try the $15.xx part before going the homebrew fix, aka. 1/2" npt with nipple route.

              • Q:

                The hose that connects to this connector is not a snug fit and leaks also since replacing. Is there anything special to reconnecting this hose or maybe the hose is bad to?

                  don't listen to customer care answer. ditch the quick disconnect and pick up a 1/2 threaded NPT fitting with a 5/8" hose nipple on the end and 2 1/2 ft of 5/8 heater hose and ditch the quick disconnect altogether.

                  I just broke one, too. Knock it out with a small chisel. I had to go advance and get a tap to redo the threads afterward.

                • A:

                  Using a Large bore "Easy Out" worked nicely for me, also no need to re-thread the hole. I thought of chiseling, and then someone else reccommended the extractor. I found a socket that grabbed the top of the extractor, and used the rachet to back it out ever so slowly. Once it started to turn, it was out in no time at all.

                • A:

                  It is very soft metal and you can use a nail punch or any small tool like that to just push the remainder of the fitting out. Just drive it straight down as close to the outer edge as possible - it will crumble easily.

                  Then just a stiff piece of wire or any pointed tool with a right angle such as a dental pick will remove the rest of the pieces from the threads. I had the intake out for this and did not have to deal with pieces falling inside the motor.

                  Do not use the Dorman replacement since the white plastic either can't handle the heat or the antifreeze and won't last even a couple of months before it fails on you - in a big way. Either buy the more expensive part with the black plastic piece or replace with a standard nipple and hose clamps.
