Dorman 800-403 Heater Hose Connector Compatible with Select Models

Changed out the heater core on my 2001 Ford F-350. I got two of them to replace the old ones due to they had not been off for 22 Years. They worked good. Cut the old ones off and put the new ones on. Depending on How much money you would like to spend and if I had to do it over, I would buy new hose to put Them on. Only problem I had with them or the old ones I ended up buying more than one tool to get the ends unplugged from the heater core. Ended up I built my own tool to do it with. Wasted money on buying what I thought was suppose to work.

Used on my 2002 f150 heater hoses coming out of the firewall and were very easy to install, used some dielectric grease to help installation.

Heater hose core broke on my Mazda 5 while during deliveries, purchased this, installed it and I'm back on the road. Only thing is I used extra hose clamps to make sure it was on pretty good.

This fit and worked perfectly on a 2008 town and country

I needed the white plastic retainer clip out of this kit. The new Dorman heater hose came with its own black retainer clip but it did not fit over the heater core tubing. It was way too tight. I had bought this kit thinking the truck might need new O-rings but instead just ended up using the new o-rings from the replacement hose in combination with this retainer clip. Oddly both parts are made by Dorman so I can't understand why the clips wouldn't have been identical. I bought 2 of these and am saving the second one for future repairs.

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.

When replacing a heater core in a 99 F150 I decided to replace the heater hoses because the quick connects are a nightmare to open up and I did not want to deal with them again. One of the heater hoses runs $75+ from Ford Motorcraft. An identical hose from Continental is $12. The trouble with the cheaper hose is that the quick connect is too large. I swapped this part with the one that came with the Continental hose and had it put back together fast. The connector is built as well as the OEM Ford part and fits the heater core lines perfectly.
