Where is the cooling fan switch located?
The thermostat housing on the left side of the engine is where the cooling fan switch is located.
Does the thermostat control the radiator fan?
The thermostat in the cooling system controls many of the electric fans. When the temperature in the engine reaches a certain preset temperature, the fan will begin cooling the engine. When the temperature dips below that preset temperature, the fan will turn off.
Where is the fan relay located?
The fan relay is located on the driver side firewall. It is at the very end where the firewall and left front fender meet. There are two relays in that location, one is the fuel pump relay and one is the fan relay.
Should radiator fan turn on when AC is on?
Both radiator fans should always run when the AC compressor is engaged. To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees.
Does the radiator fan affect the AC?
Likewise, does radiator fan affect AC? Yes, a broken radiator fan can cause the air conditiong to stop working. The AC system depends upon being able to dissipate heat into the engine coolant. You really need to have the fan replaced, or at least, have a diagnostic check to see what is causing the fan to stop working.
How often should cooling fan come on?
Most fans should come on when the coolant reaches about 200 to 230 degrees. An electric fan SHOULD NOT run all the time. A mechanical fan WILL spin as long as the engine is running, but it will only ‘lock up’ when needed.
Should engine fan run all time?
An electric fan SHOULD NOT run all the time. A mechanical fan WILL spin as long as the engine is running, but it will only ‘lock up’ when needed. It’s normal for some vehicles to have a fan run for a few minutes after the car is shut off, generally to keep the engine cool.
How do I know if my coolant temperature sensor is bad?
What Signs May Signal Your Coolant Temperature Sensor May Be Failing?
- Poor Fuel Economy.
- Irregular Temperature Readings.
- Black Smoke from Your Exhaust.
- Your Engine is Overheating.
- Your Check Engine Light is On.
Can I drive my car with a bad coolant temperature sensor?
It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicles coolant sensor is a critical component used by the engine management system. It directly effects, cooling and fueling of the engine and therefore effects how the engine performs.
Can you bypass a temperature sensor?
No, if the thermistor is bad, you can not bypass it. It must be replaced. If it is near its rated resistance value, then so far, it is good. When a thermistor is failing, it’ll display incorrect temperatures, or you’ll see impossible temperature fluctuations.
How much is a temperature sensor?
The average cost for engine coolant temperature sensor replacement is between $134 and $155. Labor costs are estimated between $83 and $105 while parts are priced at $51.
