Engine overheating Engine is overheating. Temperature rises and continues to rise as long as motor runs

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

the usual suspects are:
stuck shut thermostat
clogged raiator
dead water pump
low coolant level
it's sunday, rovers don't work on sunday.
Then again, maybe its wednesday, rovers take half a day then.

Coolant temperature sensor/sender malfuntion or wire to it shorting to ground. Disconnect wire and check gauge. If not rising replace sensor.

Hi! The MAF (mass air flow) sensor is surely faulty. The MAF has big contribution on the engine performance specially on the idling an vacuum supply. If the MAF is faulty the rpm will drop eratically or die. Regarding the overheating problem, you may want to check the radiator blower for it may be tripping that sometimes it works and sometimes won't. This can be a good cause. Hope this helps and thank you for using FixYa!

your thermostat might be the problem if the engine is actually overheating,if it is not overheating the gauge itself may be faulty....hope this helps.....cheers

The coolant temperature should rise until the gauge indicated roughly half. if it continues to go until it reaches the red "H" shut the vehicle off and wait for the car to cool off. The most likely cause of this is the thermostat. It is a $4-$10 part and usually is easy to change. Thanks for asking!

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

If this truck is not overheating, then I would suspect the temperature sensor, if it is overheating then this must be repaired first. The sensor should be mounted in the intake manifold. Hope this helps, let me know

why does the cooling fan start working as soon as i start the car and doesn't shut off until i turn off the car?

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.
