    Always assume the engine is overheating, if it is and you ignore it then you will be buying a head gasket job to the tune of about $1500.00, and maybe an engine, $4000.00. Get it checked.

You can start your car use a temperature Gage the wife might have one that showes the temp.
match it to your temp Gage if its lower than the actual temperature you need a temperature sending unit you might want to check to see at what temp the fan comes on and off if that's not working you need a temperature censor switch

hope this helps you

Check the real value of the temperature sensor with a scan tool. Compare it withe the value in the gauge. It can be a defective temperature sensor or a damaged gauge...or else the car is really overheating

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.

On my 1995 Camaro 5.7 LTI Low coolant light comes on after car warms up---coolant level is fine and car does not over heat-- runs at about 180 degrees

Since the car does not over heat and the coolant is not low there is a good chance that the sending unit is bad. If that is the case you really don't have anything to worry about. Just be sure to keep an eye on your actual temperature gauge. Those lights are hardly ever right but your gauge is almost always accurate. If you have any questions please feel free to ask. I hope this helps you out.

Hii I'm new to cars. My 92 prelude gauge still


I understand being new to cars, but that is ok. I am hear to help you. Some cars run hot, that is normal in a lot of cars. As long as it does not go into the red or way over the half way point your ok. But this is what I would do, this will make sure that car water temp/engine temp is working properly. First of all check your engine oil and make sure it is full at the dip stick. And then do the same with your radiator, make sure it is full with antifreeze. Also, you can have the antifreeze checked, they can test it, to make sure the right mixture of antifreeze and water are proper mixture. If not enough antifreeze compared to water ratio is off, then that can cause some over heating or possible over heating issues. So, in conclusion: first things to check is engine oil level and antifreeze level and mixture. I hope this helps you, thanks mike, expert fix ya man.

stop and go traffic will make the car heat up,, make sure you have air flow through the radiator fins, also make sure that the ac fan is actually engaging the fans work on a sensor and if they don't work, neither does the fan.

If you radiator is full ,as in you have no leaks, it is most likely going to be a water pump issue. Unless you have a serious clog in the system, but chances are its the water pump, not an uncommon thing to go wrong

Heat gauge shows hot , have to add antifreeze although no leak

Very common fault is head gaskets.  causing coolant consumption and bubbles in radiator.  Run vehicle, have a friend accelerate once or twice hard, while you smell exhaust for sweet smell of burning coolant.
