Low coolant in system and heater core needs to be flushed or changedAnswerThere could also be is (air pocket) air in the system. If motor is cool and resivoir is full. Fill radiator from upper radiator hose run till warm then re-check resivoir. AnswerClassic head gasket leak, (a bad one probably ) Answerone thing every one missed is the thermostat if the colant is full and the car is running good other than the cold air and over heating i would change the thermostat before i would the head gaskets, one way to check the thermstat is to start the car and let it run till the gauge gets to mid range, shut the engine off and feel your radiator if its cold your thermostat is bad, another method is to pull the thermostat it should be closed when its cold, put it in a pan of water and heat it to between 185 to 195 degrees using a thermometer to check the temp, once that temp is reached the thermostat should open if it does its good and if it does not than its bad. if its a head gasket it will show one of these signs, one of the biggest signs on a couger is white smoke out the tail pipe, wich is burning antifreeze, another sign is water in the oil wich will make the oil on the dipstick look brown and milky or white and milky, another is oil in the water wich if you look in the radiator there will be brown or black spots of oil. if any of these apear you have a blown head gasket,the other way you can check is to buy a compression tester and test each cylinder for the correct compression.

On a 2000 Mercury Cougar : The warning light that looks like a can with an X through it , located between the engine coolant temperature gauge and the tachometer ( at the bottom of the gauge cluster ) is your ( LOW engine cooling system warning light )
Is vehicle actually overheating? Could be a bad temperature sending unit or gauge Check temperature with a thermometer If thermostat does not open vehicle will overheat
Yes, because your vehicle will overheat.
Your car is starting to overheat or your thermostat is going out. Get it checked.
mostly likely something wrong with the sensor or gauge.
well your car needs a new body kit because that contributes to the temperature of the car
Does vehicle overheat rapidly? Do you have heat? Does temperature gauge show that vehicle is running cold
If you temperature gauge is going up and down then you may have a problem with your sensor. You should take your car to a professional to ensure that you don't overheat your car.
You have to pull the gauge assy out and the lights are mounted from the rear. Run1
Connect a gauge to the low side ac port. Connect Freon to the gauge. With the ac running, open the valve and allow Freon to fill the system.
Check your thermostat. Looks like it is stuck open and needs replacing. That could be why your engine is running cold. Atleast its not stuck in the closed position.
The gauge on the far right side of the gauge cluster is your engine temperature gauge. The normal operating temperature is at the half-way mark. If the needle raises above the 3/4 mark then the car is overheating. A light will come on also if it begins to overheat.
No - the gauge reports 'real-time' the engine temperature. If it is wrong, there is a problem with the sending unit on the engine. This is a pretty easy fix...
If your engine thermostat sticks open it will run cooler on your temperature gauge and you won't see the temperature gauge go up to the point where your engine thermostat opens and then the temperature gauge will show a drop in temperature , your check engine light will probably come on , your gas mileage will be less , the heat from your heater probably won't get as hot If the engine thermostat were to stick in the closed position your engine will overheat ( but there are several other causes for an engine to overheat )
There is the ( low coolant ) warning light that is at the bottom of your gauge cluster between the engine temperature gauge and your tachometer
It is quite possible in a 1996 Mercury Cougar, that when the dashboard instruments all quit at once, there is a fuse that has been blown. Most of the gauges in the dash run off the same fuse in most vehicles.
There is a battery light above the engine temperature gauge
i dont really know but i think it is 700k? i d k you tell me
Head gasket. Do block test for gases in coolant
Its a sign that either your battery or alternator is starting to fail.
I believe that is Motorcraft DY961
Yes the temperature gauge will still work. If it stuck open the car will run cool. If it is stuck closed the car will overheat.
i have a 2000 mercury couger well lets see i changed my controle temp sensor and mine stuk to cold but when i put my old one back in it went to normal they told me it was my mass air flow sensor try the both of them they ain't but 20.00 bucks a piece its one are the orther.
replace temperature gauge
