Heater hose connector at firewall is broken

Hi. I just had the same issue on my '99 Silverado last week. There are two connections for the heater hoses to the Heater core. One is white and the other is black. The Black one is available at any autoparts store for about 5 bucks but the white one is a dealer only part that the autoparts store guys will say does not exist. That is the bad news. The good news is that you do not need to use the dealer only part. The black fittings worked just fine for me. You will need to use a fuel line disconnect tool to remove the existing fittings from the heater core. These should run between 10 and 20 bucks for a set. Good luck. Joe

Actually, those connectors were a mistake, courtesy of General Motors. A simple fix is to get rid of the plastic connector. Ok....where your two pipes come out of the heater core at the firewall...sometimes they are so brittle, they will come out with relative ease. Sometimes you need to break them off in pieces, so that all you have is metal pipe sticking out. That stub out is 3/4in. if memory serves. Which ever size it is, measure it and go to Home depot or your hardware store, plumbing section. Get a brass nipple. Say its 3/4s....get the nipple with threads on one end, smooth pipe on the other. The whole thing is about three inches long. believe it or not, that nipple will thread it self into your metal stub out coming out of your heater core like it was made for it. If it makes you feel better, swab your threads with water-pump RTV silicone gasket maker, or equivalent, then, with your water-pump pliers, line it up square, and thread it in slowly. It will fit like a glove! This retro-fit is so popular, a lot of auto parts stores actually keep these "nipples" behind the counter for just such an occasion. I did the same thing on a 1999 1/2 chevy 4x4. That was 8 years ago....and its still in there today.


Try to post back and let me know If I helped you solve your problem. It will help me with my rating....! Thanks

Heater hose broke off at firewall.there is a plastic connector which I can't get off. it spins but does'nt back do you remove this connector?

There is a removal tool to release plastic locking tabs at back near fire wall, I had the same problem with my 01 silverado I used a 4" piece of hacksaw blade held with vice grips and cut aluminum cover and pried it apart to release, be careful not to cut heater core tube.

Plastic heater hose connecter that connects to heater core broke where do i get one

I just got one and it was a dealer item.No part place seemed to carry the connectors. You will need a AC/Fuel lineDisconnect Tool Set to remove it. The white connector is a 3/4 disconnect tool and the black one is 5/8. The tool kit was 14.00 and the part was 57.00.

Male fitting on heater core inlet broke off in hose

RKmastertech is incorrect. That plastic fitting is seperate from the aluminum heater core and can be removed by means of a special quick disconnect tool, like OTC 6046. Rock auto has the fitting for $5 plus shipping, just for a reference.

The nipple on the heater core that connact the

Unfortunately the heater core must be replaced because the nipple is soldered to the heater core and access to the core for resoldering is not possible unless the heater core is remove and so if you go to that kind of trouble you should just replace the core with a new one rather than doing the repair and risking a future leak after reinstalling.
