Overheating no leaks focus 2000

SOURCE: The heat in my 1992 Jeep Wangler is not working.

The only reason it won't blow hot air is because the water is not getting to the heater core. Check to see if you have a heater control valve in one of the two lines to the heater core. If so check to be sure that is is opening and closing. If it won't open then you get no water flow in to the heater core.

check closer to just underneath the firewall--it could be a smaller problem than a heater core--Ford 4.6--5.4 engines have a tube just underneath the intake manifold that the rubber hose goes bad and it will leak towards the back of the engine.Lets hope so-what i hear its very expensive to change a heater core in an Expedition.

sounds like the thermostat gasket is leaking. Might as well change the thermostat and gasket at the same time. make sure the hose clamp is tight sometimes it needs to get tightened up. could be lealking from the hose and running down.

Good place to start is a cooling system flush and thermostat replaced.

It may be the freeze plug in the back of the head leaking, it looks like a small round cup about the size of a quarter it presses into the back side of the head, to remove hit the outer side of the inside of the cup with a screwdriver and hammer. To install use the apropriate size deep well socket with extension to hammer the new one in don't hit it in too far just until flush and also use permetex black sealant around the rim before installing to ensure a good seal also drain antifreeze completely before attempting job and be sure the seat where the freeze plug is going into is clean and dry.
