How does a fan switch work in a car?

The fan only runs when needed to help cool the engine. The engine coolant sensor or a separate engine temperature switch is used to monitor engine temperature. Extra cooling is not needed when an engine is first started, so the fan does not come on until that engine reaches normal operating temperature which is usually from 195 to 215°F. The fan will then cycle on and off as needed to maintain the coolant temperature. So the fan runs mostly at idle or low-speed when the engine is at normal picture.

How do you bring the engine coolant temperature level normal that is low in a 98 ford explorer?

If your engine coolant temperature gauge is indicating that it is running much cooler than normal ( it sounds like the engine cooling thermostat is sticking open / not closing completely ) which means you need to have the thermostat changed. You should consider if have good heat from your heater and if your check engine light comes on.

What is the normal water temperature during operation?

The assumption is that you are asking about coolant temperature of an internal combustion engine. Normal temperature is determined by the thermostat. Thermostats are usually somewhere around 185 to 195 degrees F. With a high pressure cap, the coolant shouldn't go much above 225 to 235.

What do you do when your low coolant light comes on in a Chevy silverado?

there is a level sensor in the coolant canister located on the inner fender on the pasanger side under the hood. the radiator overflow line goes to this canister. this has happened to me several times on my 2001 Z-71. all i do is add anti freeze to the hot level, after the engine is at normal operating temperature.

What is the blue coolant light mean?

automotive manufactures are now using lights instead of gauges to save money and make it more user friendly. Blue coolant light in the instrument cluster means that the engine coolant temperature is still not at the normal operating temperature (cold). Normally happens at cold start (when you first the car up in the morning for example) It will turn off once the coolant temperature reaches normal operating temperature. Note: if the coolant light turns red, it means your engine is over heating and you should turn it off before you cause more damage.

How does the coolant used in car engines protect the engine?

In the car the grill that we see in front have a radiator behind it that helps cooling the engine.As you might be knowing that the engine burns the fuel to work so the engine is needed to be kept at a temperature at which the fuel do not catch fire until unless the spark plug ignite the fuel. **Coolant keeps the engine at a normal temperature lower than the temperature at which the fuel in the engine ignite.

If a coolant temp gauge is not working will it cause damage to your engine?

An inoperative temperature gauge will not alter how an engine runs, but the operator will not know if the water temperature has risen above normal without a properly working guage.
