Can anyone help me identify this metal coolant pipe? It connects to the bottom of the heater core hoses on my 2014 Expedition XL. I’ve been trying to find a part number but no luck so far.
It runs under the front passenger side wheel well and sits really close to a black metal piece. Over time, it’s started to rub against it and now has a slit in the pipe. I added a zip tie to lift it off the metal and stop further damage for now.
That’s for rear zone heat.

Thank you! That’s a big help!
Ford doesn’t sell that as an individual pipe. They only sell the entire tee-shaped assembly. It’s part of the heater hose setup. You can replace it yourself with a Dorman tee, a Dorman quick disconnect, and a generic hose to DIY it.

Thanks for the info! That gives me a good starting point.
If the metal pipe to the rear heater is the one with the hole, here’s a temporary fix: use high-temp sealant tape and a hose clamp over the hole. That should hold you over until replacement parts arrive. The Expedition’s coolant system runs at 16-20 psi when hot, so this fix should last a few days.
For replacement parts, the manual lists the auxiliary heater lines as multi-piece kits. The inlet line is part #18663, and the outlet line is part #18696. If you don’t have a manual, PM me, and I can send you pictures of the diagrams.

This is super helpful! I’ll try the sealant tape and get those part numbers lined up. Thanks so much!
