Best Answer

If water is blowing out of your radiator, then chances are you have a blown head gasket, cracked head, or warped head. Any of these will create a breach in your cooling system and allow combustion gases from the cylinders to enter the cooling system. This will iterally blow your coolant out of the radiator. The only way to fix this is to fix the breach in your cooling system by replacing the head gasket or the head. If the head is warped, it may be possible to straighten and/or resurface it.

To confirm your problem, the fan blows air but it is not heated?? I am not sure if there is a heater core in this car. The heat is generated in the engine and is transfered by a series of water pipes to a heating element(radiator) under the dash-board, the fan blows air over this radiator, it heats up and blows into the car. Things to check 1. see if the mechanical links between the temp. switches and the valves which control the flow of hot water into the radiator are functional.
