Review: na - Good product!! Great bye!!
Review: Heater Hose connecter - 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.

## Questions & Answers

**Q: What is the id of the connector / od of the pipe it fits?**
A: This is for use with 5/8" on both the ID and OD

**Q: I wan to replace my heater hose too.  What size heater hose do I use with this?  Is it 3/4"?**
A: In my experience the size has to do with the size of the pipe coming out of the heater.  So the size used depends on the heater core used.  In my case is was 3/4 for the heater core but 5/8 for the heater interconnecting pipe.  Or in short you won't know still you take it off.  But if it is the original heater core you could try and see what Amazon tells you.  Amazon was correct on mine.  Buy two Quick Connects and replace both.  If one broke the other is not far behind.

**Q: Do you need 2 of these?**
A: It would depend on the size of the lines you are working on and also if you need to replace them all.

**Q: Got a 98 Expedition 5.4l. Couldn't get them off, now I can't get them back on.. any help out there appreciated..**
A: I broke the original connectors removing the hoses from the metal tubes that protrude from firewall. I cut off the old connectors and replaced them with the dorman 800-403 connector with a clamp. At first the new connectors would not push onto the metal tubes, so I smeared a dab of tune up grease on the metal tubes and the connectors pushed right on and clicked. no leaks - worked great.

### ⭐⭐⭐⭐⭐ Works Great to Adapt Aftermarket Hoses
*by T***M on January 25, 2021*

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.
