WHAT ARE THE SIGNS INDICATING FAILED THERMO COOLANT FAN SWITCH IN CAR?
Based upon the temperature of the engine, the coolant Thermo fan switch is working in a car.
Switch is powering on the coolant fan when the engine temperature rises to a fixed threshold.
Coolant fans run continuously until the engine temperature cools down to a specific level.
Fan switch is defined as a gatekeeper for regulating the engine temperature of the car.
If it fails at any point, then you will notice the following signs in your car.
If any of the wire among the two inside the switch is cracked, then the fan works intermittently.
CRACKED SIGNAL WIRE
When either of the two wires is broken, the intermittent operations are created.
As a result, the fan turns on or off unexpectedly due to the intermittent response.
When the coolant fan switch is failed, check engine light comes on the dashboard.
ILLUMINATED CHECK ENGINE LIGHT
Due to these reasons, the additional engine hot symbol will appear in the dash.
When the switch turned on, it resulted to run the fan when the engine was off.
If the switch doesn’t run properly, then the engine generates a huge amount of heat.
OVERHEATED ENGINE
When it happens, you have to spend thousands of dollars in engine damage.
Due to the faulty switch, engine heat climbed above its temperature and exceeded the threshold.
Thermo coolant fan switch is a vital part of the engine’s life and very expensive.
CONCLUSION
Take your car to a certified mechanic for diagnosing the problem and fix it ASAP.
