Sounds like you possibly have trapped air in the system. Bleed all trapped air form the cooling system. Jack up the front of the car, and remove the radiator cap. Fill the system to the top with coolant and start the engine. Let it run until no more air bubbles are escaping. Keep it full while doing this. Also look for bleeder valves and use them if equipped. Funny thing, one side of the car was overheating. The trapped air theory seems to have been correct. I'm assuming the the gauage was all over the place because it WAS hot, and then the rush of water came in and cooled it off. Too bad I didn't figure that out sooner. I checked all of the cylinders for leaks after it overheated and found that #4 and #6 actually squirt water out of the spark plug hole. I have ceased driving the car and will fix the head gasket tomorrow first thing (hope the head is okay).

How do you fix the heat in a 94 Chevy S-10?

add water to the radiator. believe that. if there is no water flowing through the engine, your heater will only blow cold air. if there is no water flowing through the engine and your heater is only blowing cold air, and not HEATING, your heater core is probably going out or will be soon. most people believe that if you have no water in the engine then your temperature gauge will run hot and you will know that you are overheating the engine. WRONG! your temp gauge only measures WATER temp. But if there is no water to measure, there is no temperature rise showing on the dashboard gauge. if you have NO WATER in the engine you can seriously overheat your engine and not know it because the gauge is not getting any hotter than usual (sometimes your gauge will even read cooler than usual).

Your temperature gauge indicates overheating but water and oil levels are fine and heater works what is wrong?

If you are absolutely sure you do not have air trapped in your cooling system then you may have a defective gauge if you are getting heat through your heater. Usually I would say you have a coolant flow problem with either a stuck thermostat or a bad water pump but if you have heat from your heater, then you must have circulating coolant in your system. I would check the gauge or the sensor.

Faulty temperature gauge on Chevy truck?

Driving home yesterday my temperature gauge on the 2003 Chevy silverado went all the way to the right as if it was overheating. No overheat light came on. I pulled over and checked everything and nothing was hot and it had water. So it wasn't actually overheating but the temperature gauge was all the way to the right as if it was overheating. After getting home I let the truck sit awhile and restarted it and the gauge didn't reset. What causes this and how can I fix it? Thanks for your time! Also reset it by disconnecting battery it was good for two days after turning key off and on the needle keep going higher and higher. Can you help I changed sending unit no luck now what?

Can the thermostat be bad if the heater doesn't work?

If you are not getting heated air blowing from the heater core and your engine coolant temperature gauge is showing LOW or below normal , ( then YES , IT'S POSSIBLE that your engine cooling thermostat is sticking open )

Look at the engine temperature gauge. If it goes over 200 degrees, change the thermostat as it is stuck and therefore not allowing coolant to the heater core.

The thermostat is the most likely culprit. The major clue is that the engine temp stays in the lower middle of the gauge - the heater core would not cause this. The thermostat is most likely stuck in the open position - needs replacement.
