my 95 cutlass supreme had a leak in a hose a sprayed antifrezze everywhere. after cutting the hose where the hole was at and putting it back on we also replaced the thermostat and kept it stocked with 50/50 antifrezze. it still overheats but it blows out cold air. i was told it could be the radiatior, the water pump, the heater core, or that the antifrezze had anough time to get back into the motor after it went bone dry from the leak. any luck?

With the engine cold remove radiator cap star motor check for movment of the water in the rad, if its moving the pump is ok next get the car warm ,turn off the motor and feel the hoses each side of the thermostat housing if its cold on one side you need to bleed the water system of air ,it sounds as if its air locked after you lost the water.Check your enging oil if its a grey colour the head gasket /block problem. Hope this helps Merry christmas.

Who replaced thermostat ?? Are you sure it installed correctly, yhey have a top and bottom. If it was water pump, very seldom, the pump would be leaking not overheating. The heater core cannot possibly cause overheating. That sentence about the anti freeze is baloney. Anti freeze has nothing to do with the temp. of the engine. Let your engine warm up then turn on heater and feel both heater hoses, they should both be hot. If not check the heater coolant control that is located on one of the hoses. At the age of your car I would highly suspect it. After you finish with that, turn off the engine and feel the inside of your radiator core, if you feel any spots that are cooler than others, you have a plugged radiator. Remove it and take it to a radiator shop.

On most vehicles there is a valve that regulates the hot water flow to the heater core. Some run off a vacuum line, that could have come off. Others use a cable and they will stick also. Check those first before replacing the heater core, they are expensive and hard to replace if you have a/c. One of the first two are cheaper and probably the problem.

I dont think its a head or head gasket. If it was white smoke would be coming out the exhaust. It sounds like the water pump. If the rad. was bad it would still blow warm air. If it was the heater core the care would not over heat. DO THE FOLLOWING WITH THE ENGINE COLD!!!!
Take of the rad. cap. start the car. If the antifreeze is moving then the waterpump is ok. If there is no movement then chance are its bad.

Seems to me there is still air circulating inside the heater core instead of radiator fluid.
Everyday before starting and heating the car add 50/50 antifreeze mix to the radiator not the burp tank.
Do not worry about overfilling radiator.. any excess fluid will burp into the burp tank. Hopefully this forces the air out of the heater core and radiator fluid into it. Enjoy the heat. If no heat the heater core maybe hopelessly clogged.
If there is still radiator fluid loss you will have to add antifreeze often. Never when the engine is hot. Steam and hot antifreeze can fly out of the radiator with enough force to send someone to the emergency room.

the fan should come on about 180, if not the electric controlled switch could be bad, there is a sensor that detects the temp and turns on the fans, this is probably not working thats why it will run hot, other that a cracked head or a clogged cooling system that besides the water pump will be the most likely problem, if you live in the south where the ambient temp is high i would add another fan too, it would have to be installed on the inside of the radiator because with the 2 fans on the front of the radiator there is not room for a third, , those 3.8 l engines do not do well with alot of excess heat

Try this. Start your car with the radiator cap off. Let the car warm up, make sure the fluid level is full when you look into the radiator,the coolant should be moving as you look in. Check your heat, if it isnt hot then the heater core is clogged. If the coolant isnt moving after the car is warmed up then the water pump is bad. REPLACE THE RADIATOR CAP BEFORE you turn off the car..... this is very important!!!! Good luck. :)

Replace your water pump, that should solve your overheating problem. If you still don't get any warm air then proceed to replace the heater core. Hope this helps!
P.S. Stay warm :-)

Be careful on the road, and be prepared. Go to a your local bank and tell them your problem, be very sincere. They will loan you money to fix it or get a new car. It is time to get a new car. That happened to me on my 2000 Dodge Durango, so I did the above mentioned, and they referred me to 4 dealerships and they loaned me the money to buy a brand new 2007 Nissan Versa. The payments are 230 a month and the gas tank fill up is now 25.00 versus 45.00 a tank.

either you have a cracked head, or your heater core is clogged up which means you will need a new heater core, had a ford Taurus do that twice
