What do you check next on a 95 dodge neon which over heated again after changing the thermostat and radiator cap heater core not leaking?

severe overheating may cause a blow out of the head gasket. Does the radiator build up excessive pressure quickly? can you see bubbles in the coolant? any white vapor or smoke from the exhaust? These are signs of a hole in the head gasket but you may have none or all of them. Check for water pump operation by looking for circulation in the radiator with the cap off, the water should swirl or at least move around. If it is still you may just need a water pump but at the same time look for those bubbles that I mentioned earlier that is a sign od exhaust gas entering the coolant system and will quickly force all the coolant out of the radiator through excess pressure. I was able to limp my Rodeo along for a week by using an old radiator cap and tearing out a small section of the gasket so that the pressure could escape without driving out all my coolant till I was able to tear down the engine.

Your car over heated what should you check first its a 2002 Chevy Malibu?
First, try the thermostat, then the radiator, after that try the water pump, also check the hoses for any that are collapsed or leaking.
What is the Function of a thermostat?
The function of a car thermostat is to ensure that coolant gets to the radiator when it should. It blocks the coolant from reaching the radiator when the radiator is cold, and then lets it flow once it is heated up.

How would you know if the thermostat has to be changed?
Your temperature would usually fluctuate. But if your car has over heated then there is a chance it may need changing
What is the right way to install a thermostat on a 1992 Sundance Which part of the thermostat is facing toward the engine?
Some thermostats have an arrow embosed on the one of the legs pointing toward the radiator. Generally speaking, the side with what looks like a spring and cylindrical bulb should be immersed in the heated water from the engine. Since the water in the hose attached to the radiator is not heated by the engine, this would be the wrong side. Also, on my Sundance (2.2L engine), the thermostat fits only in the correct orientation (try a dry fit first). Spring into engine.
If your 1994 Mustang is overheating and the radiator may be leaking can you just remove the thermostat?
You can remove the thermostat, but you son't want to. That will cause the computer to think that the car has never heated up properly and make it run as if it needs to heat up. This will affect fuel economy, power, and longetivity of the engine. You will be better off fixing your cooling system wherever the problem is. DO NOT REMOVE THERMOSTAT!!!!!!!!!!! the Computer will run in Limp Home Mode forever until its replaced, really bad economy,Worse Performace,will run the cooling fan constantly.
Does the thermostat control the heat in your car?
No, the thermostat controls the temperature of the engine coolant. As long as the coolant temperature is below the thermostat set-point, the thermostat remains closed. Once the temperature arrives at the set-point, the thermostat starts to open, sending heated coolant through the radiator. The radiator then cools the heated engine coolant and the water pump forces the coolant back through the engine. The heater control valve allows more or less of the engine coolant through the heater core. Since the coolant should be very near the set-point temperature of the thermostat, you should be getting hot water through the heater core to warm the inside of the vehicle. The engine coolant is there to keep the engine from melting down or from breaking metal parts and burnng off the oil. It just happens that the heated coolant is useful to warm the inside of the vehicle.
Why is your 200 Lincoln ls overheating after a new thermostat was installed never over heated before install and the thermostat is installed correctlyhow do i correctly burp the system?
You should be able to run the car with the radiator cap off and when the thermostat opens, it will suck in the coolant and then top it off. Either that or there must be a bleeder screw atop the thermostat housing for bleeding.
Describe a convection in a room heated by a radiator?
it hotter
Why would the internal heating of a 2001 deawoo leganza not be working even thought the engine thermostat has been replaced and the systme has been bled?
It's probably not getting heated coolant to the radiator. Check the heater control valve and the control on the dasboard.
Why need auto radiator reservoir?
Engine coolant expands when heated. Heated coolant needs a reservoir to come and go as needed.
Why does 1989 Acura Legend get over heated?
Could be one of several things: 1) coolant level too low 2) thermostat no good and needs replacement 3) radiator needs replacement 4) upper or lower radiator hoses punctured 5) bad water pump 6) electric fan malfunctioning and not turning on
