I have a leak coming from here. This is on the passangr side. Not sure if it is the hose that runs along the fire wall where it attaches to it or if it is leaking from a crack or a seam. I don't know what it does and if it can be fixed/cleaned or has to be replaced? I can't find the part on line (not to say it isn't out there I just can't find it) if I knew what it was called I might have a better shot at finding it. Do you know if I can pull the hose lines off or do I need to remove fluid first?
Thanks

Thats the aux pump that ensures adequate heater water flow to the front and rear cores. The plastic can break, or the front and back halves can get loose (have no idea how). You can try first just tightening the four small philips screws on the pump. Sometimes that squeezes the two halves of the plastic pump together more allowing the seal between then to work again. If the plastic is cracked, the pump is not tough to replace, two hoses and one electrical connector.

To find the leak, hook up a cooling system pressure tester. https://dodgeforum.com/forum/2nd-gen...ss-4-7l-2.html
Heater hose can be had from any auto parts store for cheap. I bought a six foot roll at advance and redid mine. Here is something to think about. Unless it's leaking right at the firewall spouts, don't pull off the old hose there. Cut it and couple with new hose. (I coupled mine with a heater valve from the junkyard, so I could stop coolant flow altogether in the summer). https://dodgeforum.com/forum/2nd-gen...e-install.html Reason for this is, those heater pipes at firewall are highly malleable aluminum, which will deform and leak if you fool with it too hard. Screw up those pipes and you'll be pulling the dash.
