SOURCE: Overheat

Check or replace the tps, but first, maybe give the radiator a flush and check fluid level

SOURCE: the temperature meter rise when car slows down and

does the engine idle faster when the air cond is on ..if not it may be the sensor that controls idle ,it has to go faster to compensate load ..anyway your radiator could be blocked feel the top hose n bottom should be a noticable temp differance

99 ford taurus starts up but doesnt drive more than 10 miles per hour and temperature starts to rise


maybe a coolant thermostat that is faulty, a collapsed or perished hose..

It could also indicate cylinder head gasket/cylinder head problems.

Ten miles is about the correct distance for a car engine to reach normal operating temperature. If your temperature gauge continues to rise beyond normal ..ie. overheating .. you risk causing a lot of damage to your engine.

If you're not sure what to do or look for - get somebody to check it out for you

Big white fan connected or near radiator not working causing my temperature guage to slowly rise while im driving the car. i then switch my air-con on while driving slowly temperature goes down


That's the radiator fan malfunctioning. Check the fan motor itself by conecting direct to battery while disconected from harness. If not OK replace. If OK check the fan switches, These are sensors that turn the fan on when temperature rises. If bad replace.

Temperature rises,is the water pump damage?


before to suspect water pump not working. need to check radiator cup, if temperature rise on stop. engine thermostat is the other factor of overheat and notice the temperature begin to rise from start up. leaks from radiator is the other factor,coolant is not enough to support the system.

Over heating


When your temperature gauge reaches "H' it may too late to prevent a major breakdown. Knowing the symptoms of an overheated car and how they occur may be the difference between being inconvenienced and incapacitated.
Identification:---Other than a low oil level or low oil pressure light, there is not a more significant part of a car's instrumentation than a rising temperature gauge or a glowing "Hot" light. These lights are really the only confirmation a driver has that his car is really overheating. It is the identification of the symptoms of an overheating car that enable the motorist to avert a badly damaged engine. Overheating is always a traumatic event for a car's engine, which makes the early identification of the symptom an important addition to the informed motorist's tool kit.
Stuck Thermostat:--The car's thermostat is a valve that controls coolant flow from the engine block to the radiator. When the engine is cold the thermostat remains closed so that the coolant can reach operating temperature quicker and also provide heat to the passenger's compartment. The thermostat has a spring on it that moves depending on coolant temperature causing the thermostat to open. Sometimes the thermostat fails to open thus restricting coolant flow to the radiator where it would be cooled down. This condition is often the cause of overheating. The symptoms of this cause would be a rising temperature gauge and possibly the loss of heat inside the car.
Restricted Radiator:---A car's radiator will have thousands of gallons of coolant passing through in its lifetime. Along with the coolant comes particulate matter in the form of corrosion breaking loose from various parts of the car's cooling system. These contaminates collect in the tubes of the radiator reducing its efficiency. Extensive "plugging" in the radiator will cause the car to overheat. The symptom of this condition would be a rising temperature gauge which goes up when you accelerate.
Coolant Loss:--A car's cooling system is a closed loop system. You are not supposed to lose coolant. Sufficient coolant loss will cause the engine to run hot because engine is heating less coolant to higher temperatures. The symptom of overheating induced by coolant loss would be a pool of coolant on the pavement when the leak is external. Steam under the hood as the lost coolant hits hot parts of the engine, or a rising temperature gauge in the case of a undetectable engine related leak. Of course, the gauge would also go up if the leaks were not detected. Deteriorated Water Pump:--Cars use a belt driven pump to push the water and coolant mixture through the cooling system. This part is called the water pump. Rarely the impeller that draws the coolant through the pump will rust away making it impossible to push any through the system. If this occurs the temperature gauge will climb and coolant will boil over in the radiator. Inoperable Fan:----Most cooling fans are electrically driven. Some are driven by fan belts. If a belt breaks or the electric supply to the fan is interrupted overheating may result. Electric fans are tuned on thermostatically when needed. When the car runs at idle for extended periods or the weather is extremely hot, a failed fan will cause overheating otherwise it serves as a standby assist to the rest of the cooling system. In stress conditions an inoperable fan will cause the temperature gauge to rise. This will help. Thanks please keep updated.please please do rate the solution positively .thank you for using fixya

Engine warning light 2004 focus temperature rising


change your thermostat, and your temperature sensor. The sensors can have a tiny crack in them and cause a lot of problems. Once this is done you should notice a difference. Special note, check to ake sure your fan is coming on, and that your water pump is good. Remember if you change your water pump, you must change your timing belt. If you don't you will be replacing them both in under 6 months. Also make sure your coolant is still good.

1997 Hyundai Elantra has heat but temp gauge does not rise.


If the coolant is below a certain level, the temperature sensor will not read anything and the temp gauge will not rise. Replace the cap, and check that you have enough coolant in the system. If this does not solve the problem, you will need to test/troubleshoot the coolant temperature sensor.

Rapidly rising temperature in 2000 Olds Silhouette


Could easliy be your water pump. The coolant in the radiator isn't being forced through the engine by the water pump causing the coolant to be cool and motor overheating. A thermostat can also cause this problem, but I belive it's the water pump.

Location of toyota camry 1995 themostart


Hi Ade

Its normal for the temperature gauge to be at almost half when the engine is warm. If it rise above the half then you have cause for concern or if it is well below half when your car is really warm, then you may want to check it out as well.

91 buick runs for awhile, engine light comes on, car shakes then quits. fan wont come on to cool it, how do i repair it?


Perhaps if you could provide a little more information or observations, it might be easier to isolate the problem. For example, it appears you may have a problem with the engine overheating and then your engine dies when the extreme temperature is reached. When you start the engine, watch the temperature gage on the instrument panel. Does the temperature rise slowly (lets say over a period of 10 minutes or more) or does it rise quickly to the point of overheating (less than 5 minutes)? If the temperature rises slowly, it is probably just that the thermostat needs to be replaced. The thermostat is usually located in a housing where the upper radiator hose connects to the engine. If however, the temperature rises rapidly, that indicates a more serious problem. Your engine may have a blown head gasket which is venting hot exhaust gases into the cooling system causing the temperature to rise rapidly. I recently had this exact problem with my Chevrolet Venture which, like your Buick, is a GM product.
As far as the fan motor not coming on, the problem might be the fan motor itself. One way to test it is to connect the fan's electrical leads to a 12 volt power source like your car's battery. If the fan works, then the problem could be with the Engine Coolant Temperature sensor (ECT) which screws into the intake manifold. The ECT senses the engine's temperature and tells the fan when it needs to come on to start cooling. I hope some of this helps.
