Check the Antifreeze level. It sounds like it is low.

    Since you gave me a thanks for trying, I would assume that you checked that. It might be a water pump. Are the radiator hoses and the heater hoses getting hot when the gauge is reading hot?

HEATING ISSUES


One way to tell a bad thermostat in a car is if the car overheats frequently even if there is water in the radiator.Stuck open - no heat from heater, temp gauge hardly moves off of cold.
Stuck closed - overheats engine, temp gauge quickly climbs to hot.listen for any rubbing, grinding, or whining noises from the pump. look under water pump while running, if pump is going bad. water will come out of weep hole on the bottom of the pump. good-day!

Temp gauge stays cold


If the thermostat is bad (i.e. stuck open at all times), this would allow coolant to circulate in the engine even when it is below the desired operating temperature. This leads to OVERcooling of the engine. You can either replace the thermostat as a first step or remove it and test it -- closed when cold, open when heated above 190-200F.

My 2000 Montana gauge is showing that's over heating even when it's driven a short distance and when driven on the freeway it's not smelling like its over heating or there no steam coming


If the gas gauge does not work correctly and the temp gauge reads hot, you could have a problem with the instrument panel.
Both gauges get power from the same circuit, but each gauge is grounded by its own sending unit.
If the temp gauge is reading correctly, you could have air in the cooling system and it is not actually full of liquid coolant.

My temp gauge stays on hot but not over heating and the heater is blowing cold


you might have a defective sender unit (temperature) or faulty wiring to the same unit.Identify the sender unit and disconnect it whilst your ignition is on. Temp gauge must fall to cold.If it does, sender unit needs replacement and if it stays high your wiring to the sender unit is shorting with ground

I have an Audi A4 1.9TDi 2004. I was driving a distance of 25km and the car temp gauge went up twice on the journey and I got message on the dash COOLANT with a pic of a thermometer. I then drove 80km...


Make sure you uhave a good mixture of antifreeze it make the boiling point higher as well as the freeze point lower. Check the fans let it idle turn on the ac and wait and watch.If it gets hot and No fan comes on start there / thermastat The t-start should be open around 160-180 degrees you should notice it get to the threshhold then drop 10 degrees / heads check for water in the oil oil in the water .See if you can get a temp gun if every thing else checks good before you get into the wiring.

Check coolant level, and possibly replace thermostat. When a thermostat gets stuck in the closed position, coolant does not circulate thru motor. Gauge stays midrange when driving, because motor is being cooled by air and or the fan. If car seems to operate completely normal, then the gauge is faulty.

Heater not working,engine smells hot,temp gauge stays in blue zone


A. Do you have a Coolant Leak causing the smell? What is the Radiator Coolant Fluid Level? Have you been adding alot of Fluid?
OR
B. Replace the Thermostat. The Thermostat is stuck closed.

Either one A. or B. causing the:
1. Engine to overheat, because there is not enough fluid or the thermostat is stuck closed not allowing fluid to circulate.
2. Heat is not working because the heated (hot coolant) is not travelling to the heater core.

No heat inside while temp gauge climbs highest


your heater core or the hoses going to it are bad. get them replaced and i gaurantee this will solve your problem. if the antifreeze is coming from the very front of the car than you have a bad radiator or hoses in the front of the car.

No heat in car and temp gauge rises while driving but stays half


With engine cold, remove rad cap & check level in rad. Top it up if needed to 1 or 2 inches from top. Start engine, turn heater on (not defrost) and observe coolant level as engine warms up, add if necessary. Radiator fan should be off, and only come on when engine reaches normal operating temperature, for a short time, then shut off again. Let it run until that happens about 3 times, then put rad cap back on. If temperature gauge climbs up over normal toward hot, too much, shut it off. Do you now have heat? Is rad fan acting as I described? Let me know.
