Hi, Recently my car began to overheat on the interstate. the gauge went way past the high mark and i had to stop the car. I turned the heater on and a blast of hot air came out then cold air started blowing even though i put it on the highest temperture. I eventually drove home and my car is constantly overheating. i added coolant and water to the radiator overflow tank and ran the car on idle. even on idle the car still overheats. the coolant tank is full and the heater is still blowing out cold air. can someone tell me why this is happening?

to be more detailed, i drive a 94 nissan sentra. i tried to put coolant directly into the radiator cap and it all just leaked back out. i dont think i have a blown gasket since i didnt experience i misfire or loss of power when driving

Low coolant level. Add coolant directly to the radiator. The heater hoses are independent from the thermostat. Coolant flows through them all the time.
Then find out why you were low on coolant. (i.e. leak, bad head gasket, etc.)
After you fill up the radiator, run the engine up to temp. with the radiator cap off. You will be able to tell when the thermostat opens, as the coolant will start to move through the radiator. Top off the coolant if the level drops. Then, quickly put the cap back on, and feel the heater hoses. If both hoses are hot (I'm assuming you still have the heater control on "Heat") then there is no air in the system. And hopefully your problem is fixed.
What do you mean it all leaked out after putting coolant directly in the radiator?
Where did it leak?

sounds like air trapped in the engine look for a little hose highest one on the cooled down engine near the throttle chamber and slide the clamp back pull off the hose. Now go out and buy a tight fitting funnel to cram into the radiator neck it has to fit tight to get the antifreeze higher than the little hose see where I'm going with this? Water seeks its own level once the air is all out put the hose and clamp back on and try running the car again.

Check the anti freeze level in your radiator. Not enough liquid will cause the engine to oeverheat, and also, not allow any heat to go into the heater, since the level is low and it isn't enough to circulate through the heater. Hoses will collapse because of lack of anit freeze, since there is no liquid in the system, (or rather, since it is low) and so without liquid, there is a vacuum created whenever the car cools down. This vacuum will cause the hoses to suck in, or collapse. Check your anti freeze level, or have a garage do it for you

It sounds like your thermostat is stuck closed or else the cooling system is clogged up. Let the engine cool down. Take the thermostat out, either idle the engine or drive the car and see if it overheats or just go buy a new theremostat and put it in. Good luck. Pops

the only answer
first let the car cool then take off the radiator cap if their is a dipstick attached to it your car runs on dexcol ((look to see inside or on stick coolant looks like a thick substance usually gray or other dull shade)) and when you put water in that you ruined it, your whole radiant system needs flushed and refilled.
If not then you are in better shape fill both the radiator and resivoir tank with green coolant or water ((a 50/50 mix is better in the summeras long as where you are at is higher than 65 degrees)) then check for any visible leeks then start car if problem persist thermostat needs replaced.

There is air in the system. May need to have a qualified technician look at it to determine why there is air in the system. Possibilities are cracked head(s) or blown head gasket(s). Hard to say since you didn't give make and model or much of any other symptoms.

usually you need to replace the thermostat when this happens. Its a fairly cheap part and easy to replace.They often stick shut or closed. The cool air and over heating are signs that this is the problem. Simple to fix..
