There could be many reasons. Not enough coolant or bad flow, faulty thermostat, low oil. If the coolant freezes then it will overheat. If your car continues to overheat then you should have the coolant flushed and thermostat replaced.

What could cause the temperature gauge to die on a 4.0L SOHC 4x4 1997 Ford Explorer?

Check the temp sender and make sure the wiring is connected. How long has it been since the thermostat was changed and the coolant was flushed? You might try those...or at least a thermostat change. The coolant level is too low, and/or there is not enough water mixed with the coolant.

How do you know if your car needs a new thermostat?

If your radiator isnt leaking and car is having a over heating problem and coolant spewing out. Chances are your thermostat needs replaced. possible the radiator needs to be flushed. But more likley its thermostat


Your car is leaking yellow rusty water Does a radiator leak normally give out that type of water?

Yes, this sounds like coolant from a cooling system that has been neglected and not flushed and changed regularly. Have the leak fixed, a new thermostat installed, a fresh mix of 50/50 coolant installed, and bleed the system.


Why does my 2001 cavalier temperature gauge max out high and then go all the way back down to c when I stop at a light The low coolant light comes on but doesn't stay on and there is no heat?

Sounds like you have a thermostat problem. Have it changed and have the cooling system flushed and refilled with fresh coolant. That should cure the problem.

Hi there, if you have flushed any engine and have changed thermostate there are only two options that are left; (providing that there are no leaks) 1. the thermostat is faulty / 2. your water pump is broken and needs to be replaced


What makes a temp gauge bounce back and forth but doesnt overheat on a 1999 s10 changed temp sensor thermostat radiator cap and clutch on fan and flushed and changed coolant?

Make sure you have the correct thermostat in there, if it is set too high you will get that bouncing. The thermostat is set to open at a certain temperature and allow the coolant to exchange with what is in the radiator. Under normal conditions you will notice a rise and fall of the temp gage as the coolant reaches max temp then lowers after the exchange. An overly sensitive sensor or an aftermarket gage set up will exaggerate it. I would not worry too much since it is a good indication that your cooling system is working well, the coolant in the radiator certainly seems to be cooling down enough to cause a big swing in temp. Check on that thermostat though as it may be letting the coolant get too hot before releasing it.


What could still be the problem changed the heater core and thermostat flushed system to get all the air pockets out and it still overheats?

water pump


Why is it always getting rusty all the time inside the reservoir in the 1996 Ford Taurus gl sedan would it be the radiator because it needs flushed now in then or could it be a thermostat stuck closed?

Nothing to do with the thermostat, everything to do with changing the coolant on the recommended* basis (or sooner). The "green" coolant is NOT long-life and recommended to be changed more often than the "yellow". But even the 'long-life' requires changing no longer than 5 years. NOTE: Both these coolant types are mentioned in the Owners Manuals.


Why does Overflow Reservoir on 1999 Ford Taurus keep overflowing gauge doesn't read hot changed the hoses flushed Radiator replaced Thermostat and reservoir?

It sounds like you have a blown head gasket. Combustion gases can enter the cooling system through either a blown head gasket or cracked cylinder head. The gases (under pressure) force coolant out of the reservoir. This also causes a void in the upper part of the cooling system , leaving no coolant at the thermostat and the coolant temperature sending unit. The result is a erroneous temperature Reading and will even prevent the thermostat from opening.


What is making my 99 Taurus boil over at cap Already changed water pump and flushed system?

Your ford ranger temperature gauge drops when you turn on the defroster it is a 1991 you have replaced the thermostat and flushed the coolant twice?

The defrost is cooing your coolant by circulating the fluids through the heater core. Check the water pump to insure that its pumping and check the radiator for blockages in the fins. Also check for an air bubble that can happen when a thermostat is replaced.


What would cause a 1998 Chrysler Concorde to run hot?

It could be one of many things.......radiator fans notworking/low on coolant/stuck thermostat/ radiator may need to be flushed......


If your 93 Chevy is still overheating after you have replaced the thermostat what should you check next?

Has the rad ever been flushed? Try that if there is no indication of water pump failure (leaking or venting coolant from pump.)
