    Recently our heater started going in and out on us. Then on a really cold day I was trying to get some heat and the temp gauge jumped to Hot and the coolant light came on. Then after stopping, it went down again. Not sure how an engine goes from super hot to normal in like 30 seconds, so I figured it was electrical. Then I checked the oil and looked into the radiator, both were very low. Put a quart of oil in and about 1/2 a bottle of antifreeze. Heater seems to be working great and since then it hasn't overheated. Not sure what the problem was, or if it's fixed, but for now I'm not doing anything else to it except an oil change and top off the fluids.

    Have the engine tested for a blown cylinder head gasket and let me know the results of the test.

    two things... have you worked out all the air in the system... and when replacing the thermostat... did you put the right end toward the motor ?

My front defroster does not work but the back heater works.. if the van is running it will heat up but when you start driving the gage goes back to cold it blows cold but defroster wont work at all


Change the thermostat. Follow the top radiator hose to the engine. There is to T stat. That will get your heat back. on the defroster, it doesn't blow out air? doesn't switch vents? or just not get hot? Year make and model please.

1998 Oldsmobile Silhouette overheating


Is it leaking antifreeze underneath the engine at all when it sits overnight? If so I would say the water pump is shot. If it isn't leaking, it could still be the water pump but it might(hopefully) just need a new thermostat. And driving it when it's hot like that to the point where it starts to run rough means you run it too much like that and your engine will blow up and there is probably already damage. So check it out before driving it to much more.

No heat at idol low heat at speed flushed system, changed thermostat, right now do not have coolant in will that make a difference


yes if its not full of coolant it wont blow heat... let it cool down, fill it with coolant, start the vehicle with your defroster on, all the way over to hot, and on high, watch the level of the coolant, when the thermostat opens, the coolant will be sucked out of the radiator, top it off, after a few minutes you will feel heat.
