My Bronco recently began to overheat and the vent quit blowing warm air and began blowing cold air. I checked the coolant level, and it was ridicously low. I had checked it a few weeks back, and the level seemed fine.

I filled the radiator with coolant and the next time I drove it, the same thing happened all over again.

I'm not seeing any visible leaks anywhere, but that coolant has to be going somewhere...any help?

Test or Replace the thermostat-continues to overheat get it block and pressure tested-

If the block and pressure test passes check the following: ,Pressure test the Rad. cap,Clogged radiator,air lock in the cooling system ,Fan clutch,Radiator electrical fan,collaspe hoses,water pump.

don't forget to check your heater core.. and freeze plugs.. i would bet its just the heater core.. it should be behind the glove box. inside the "black plastic box" i call it the vent assembly...
