I've been having a problem with my truck overheating. Refilled fluids, replaced the thermostat, thought I had it covered. Then it was overheating again. I could hear fluid on the other side of the the engine wall, passenger side. When I got it home a brown liquid (like coffee mixed with lots of cream) was leaking from the engine compartment, passenger side. I pulled up the hood, and this fluid was leaking from one of two hoses connecting to the engine wall in front of the passenger seat. It was the right hose, toward the center. What is this, and how many of my kids am I going to have to sell to fix it?

There are 2 hoses side by side going into firewall, is it one of the hoses that are leaking or does it look like a l shaped elbow pointing down? If its coming oit of the elbow then I suspect your heater core is leaking but if it is a rubber hose going to the firewall and can be replaced then you will be in good shape. The 2 rubber hoses going into firewall connect to the heater core and the elbow is a drain for the heater box. When coolant comes out of the drain its because the heater core itself is leaking.

Thanks for the reply! It was leaking from the hose itself, not an elbow. If you're in the engine compartment (standing in front of the truck), the two hoses connect directly to the firewall in front of the passenger, next to the coolant reservoir. There is no elbow on this side. It was leaking on the engine side of the firewall, exactly where the hose connects to it.

I believe the heater core already is not working, as the heater doesn't work (blows air, but not warm). I never fixed it because I could live without the heater. But you think I just need to replace the hose? Would that cause the engine to overheat, even if I wasn't using the heater?

Yes just replace the hose. Make sure the system is full of coolant and then see if it still overheats
