    • Perfect When you just need this piece
Size: 1 Count (Pack of 1)
Last time I had to replace this piece I had to purchase $150 hose kit. So happy I was able to find this piece online and cheaply! Worked perfectly

    • Direct replacement. I don't care for this setup, but bypassing seems potentially worse
Size: 1 Count (Pack of 1)
I wanted to bypass their T system since their setup could cause a major failure- pumping coolant out and overheating. Getting a hose to fit over their ring on heater core pipes that they strategically placed into a divot in the firewall seemed even more risky/prone to failure. This fitting let me directly attach the hose to their T "quick connect" (notice it doesn't say quick disconnect) fitting. I even ordered a fitting removal tool, but it didn't work on a couple so I took a screwdriver and broke the clip retainer on the fittings that I was replacing anyway (How does that feel GM engineer? I mean you spent how many hours figuring out how to keep us from fixing our vehicles and a non-engineer (me) took a screwdriver and screwed up all your plans in less than a minute!) Small victories, but sweet non the less. Anyway, this connector let me clip directly onto their "quick connect" T fitting. As long as it lasts as long as the first I won't have to repair this again. ... show more

    • Bought 2 one fit one didn't
Size: 1 Count (Pack of 1)
2001 chevy suburban rear heater. I bought 4 pieces (all Dorman) offered together, 2 "T", and 2 straight, to replace the clip on heater hose connectors for this truck. The 2 "T" fittings for the front and rear heater core pluming fit fine. The "T's" are not designed to side a hose onto nipple and use a hose clamp. You must use these straight o ring quick connects between "T" and regular heater hose. Out of 2 of 800-403 part number, one fit either of the "T" fittings, the second straight fitting did not fit either of the "T". I could not make my cooling system whole with the Dorman parts, I had to make a trip to a local parts house and buy another so finish this job. I will not be buying these again if other brands are available. ... show more

    • Excellent!
Size: 1 Count (Pack of 1)
Nice, it got a couple of O-rings in the inside of it - you need to take the white part to see them in place. So I removed the old ones going "the hard way" because unfortunately I did not have the tool at that moment. So here what I did it without the tool. Once I got into the cab and had access to the heater core (dash removed) I had other guy pushing the two tubes from outoutside towards my direction inside of the cab. Once I had the old quick connects at sight on my hands (with this little foam cover/seal left off the way without cutting it), I had to break the old quick connects using some pliers; as plastic was worn out it was easy to do. But, if you get the tool would not be a bad idea. The only "advantage" removing from inside the cab, is that as I mention I had the old connections on my hands, seeing what I was doing. If you do it from outside the cab, you would struggle because there is no much room to manouver with the tool, not to mention you do not really see much what you are achieving with the tool so you might play around for a little while; not really bad thing to do unless you have practice or experience doing this particular job but this was the first time I did it so. Folks, do not give me wrong, these are quick connects and they really are. Yet, they are not "quick disconnect's" they are not supposed to be anyway, right? You do not want to loose your coolant on your way ;) I will prepare a youtube thing with some pictures of all the (painful) job performed later... wanted to learn myself, to have fun with this, and did not want to pay $133 bill here in Mexico for this job done. If you want the tool, see if something like this one fits your quick connect: http://www.amazon.com/Great-Neck-OEM-27106-Disconnect/dp/B004FEHZB4/ref=pd_sim_auto_10?ie=UTF8&refRID=14Y5MR0YCZCDVBP2NQP0 Anyway, hope this helps. ... show more
