"Most engines today are designed to operate within a "normal" temperature range of about 195 to 220 degrees F.", http://www.radiatorinfo.com/radtip.html, 2006 by RadiatorInfo
I check radiator fan, and relays and they are good, what can be a problem when my car reaches temperature to open termostat radiator fan does not work
It can mean that the temperature is too hot or you have a bad radiator cap.
Pressurised coolant boils at a higher temperature than unpressurised
A mechanic of my car told me that it should between 180 nd 200 degrees.
When your car is at idle there is no air flow to cool the radiator, but when your car moves the air flow through the radiator cools it down. I would suspect the radiator fan is not coming on when it should. If the fan is working properly the engine temperature should stay fairly constant assuming the thermostat is also working properly.
Radiator stores engine coolant for circulation throughout the engine The radiator is placed at the front of the engine and exposed to the atmosphere to keep coolant cool to maintain proper engine temperature
If this is about a car: the heater in a car is basically another radiator, but this one sitting inside the car. When you turn the heater on you draw heat from the engine and into the car. If you aren't running the car hard enough the temperature in the engine will drop.
The wind blows against the radiator keeping it cool which cools the engine, if it didn't the pistons would enlarge cause of the extreme temperature and could explode leaving your car a write off!
On the 2000 town car, the ambient temperature sensor is under the hood. More precisely, behind the grill mounted to the upper radiator support.
It is normal for a temperature light to come on in the VW Jetta when the car is started. If the light stays on, it is probably an early warning that there is something wrong with the radiator. The car may be overheating right away when started because there is no fluid in the radiator, or there is a fluid leak somewhere in the system.
question- what was the car without a radiator? well it's probly a car without a stinking radiator,,,
P1492 (M) Ambient/Battery Temperature Sensor Volts Too High Battery temperature sensor input above acceptable range.
