hoses are way too hot and the overflow under the ac won't stop leaking
Just got the beast running again. I noticed that the inlet and outlet (rubber) hoses going into the ac motor are way too hot. I have never felt these hoses get this hot. I have plenty of new coolant in the radiator. Under the truck near the passenger side there is a overflow hose. It sits underneath the ac motor. It has a constant flow of HOT water coming out of it and all over the ground. What can cause this, and how do I fix it? The truck is a '76 f250 ranger with a 460.

By "ac motor" do you mean the A/C evaporator housing? That's the big "box" on the passenger side of the firewall.
If that's what you're talking about, it should have an evaporator drain on the bottom. Normally water (condensate) will drip out but this should be relatively cool, it's the moisture that collects on the evaporator.
If it's hot, like 1976F350camperspecial said, it sounds like you have a leaking heater core.
The two hoses that are getting hot, if they're the heater hoses, they should be roughly the same as the upper radiator hose, so yeah, they're going to be hot.

it's old brownish rusty looking water. It's a constand flow if water not just the average condensation.

yep i would say that's it.
if you need to get up and running then remove the hoses from the fire wall a/c box in the engine compartment and connect them together with a piece of 5/8 inch pipe and clamp the hoses to it.
all that water is coming from the radiator that's why its so hot.
replacing the heater core is a pain.

so, just bypass the whole evap? correct? I would just need to attach the inlet, and outlet hoses together. Can this be ran permanently or is this just a quick fix? Would this stop the hoses from getting so hot? Anyone know the coolant capacity? I'm going to flush the system as well. Thanks guys, You are all so helpful!

This can be a permanent repair, you won't have a heater though and, if your A/C still works, there won't be much in the way of temp. regulation. It will always be "max cool".

Perfect. I know the hoses will always get hot. These were so hot I couldn't bare to touch. That is abnormally hot. I'm sure after doing the bypass and radiator flush and with new fresh coolant it will decrease a little. Thanks for the info.

The capacity of the supercooling system is 24 quarts (6 gallons). That means three gallons antifreeze concentrate and three gallons water. All other cooling systems are smaller.
Replace your thermostat while you're at it.

If the hoses are "abnormally hot" it could be that your thermostat is stuck almost closed or is a high temp model. While you're doing your cooling system maintenance, you probably should test the thermostat in a pot of hot water on your stove with a known good thermometer and/or replace it with a lower temperature model. I have that exact truck. I've been using a 160F high flow model. So far, all seems O.K.
