After many miles the coolent temp light is on

the low coolant sensor is in the surge tank most of the time if u bang on the side were the sensor is the light will go out

the most obvious cause is the head gasket ,its failing and drawing in the water so no problems with overheating or pressuring the system ,never mind the weekend mechanics who know more with the amount of beer they drink ,its failing as most gaskets will around the 100,000 mile mark regardless of make or model

This is normal, all it is saying is that with the outside temp.there may be ice on the roads. this is just a warning message letting you know it may be slippery on the roads. you will see this message go away when the outside temp rises above freezing. hope this is helpful, good day

Change the temp sensor on the left side of the engine also change the thermostat at the same time if possible flush the coolent system.I have a 2000 chevy silverado 1500 5.3 with 435,700 miles same engine 2nd ****** im having the same problem an i beelieve mine is from straight coolent insted of 50/50 mixture.Hope this works for you if so im glad i could help,also ive done all thework to my truck except for the ****** change and i put a new one in at 314500.

The blower is heat related by a temp sensor..........When coolent is at a higher temp than the engine wants the blower will cut in to lower the temp.Hope this helps.

engine is telling you that either the temp sensor is dirty or the thermostat is going bad.

sounds like you might have a blown headgasket.

Hi:
Your coolant temp sensor was not reading right, and is a sensor that adjusts your eng timing. I would keep an eye on your coolant level. That would be a bigger concern, figuring out if you have a leak. If the cold comes back, you need to change out the coolant temp sensor.

Check for codes... pay attention to idle air control, throttle position, manifold absolute pressure and intake temp sensor codes. If not showing codes, these can be tested with a good volt/ohm meter.DO NOT just start guessing and buying stuff!!!

Your thermostat will not affect the heat in your car. This is controlled by the heater core which is pulled from coolant from the engine where the coolant will be the hottest. Your thermostat opens and allows the coolant from the engine to circulate into the radiator and the coolant from the radiator flow into the engine. A thermostat is cheap and easy to replace. The sensor should be a fairly inexpensive and easy replacement as well. I would change out the sensor first because bad thermostat would create an overheating problem.
