Look in the engine bay near the fire wall behind the motor u should see 2 about 1inch dia. blach heater hoses about 3-5 inch from eachother those are ur heater core hoses one of which will have a type of box made of plastic with ither wires going into it or a vacume hose going into it on most cars this controld the flow of hot water passing threw the core as u move the heat selector from cold to hot it controls this valve perhaps this is ur problem or u have a jammed thermastat when jamed open it alows too much flow between the motor and the radd never alowing the motor to fully heat up, or ur water pump gone bad (not likely) what is your prestone mix ratio should be 60%prestone-40%water mix also make sure your rad is full a quick way to see if ur water pump is working is when the motor is cold open the radd start the car some prestone will leak out normal-- when the car gets to operating temp the lever will go down cause the thermastate will open alowing water to pass into the motor now slightly rev the motor to about 2000 rpm the level in the radd should drop every time u gass it if not might b a flow problem also if its winter in your location put cardboard infront of the radd maby one 3rd to one half of it. also check under the dash to see if the flaps in the heater /fan box move when u move the selector knobs HOPE THIS HELPD A BIT THANXX!!
