Thermo Coolant Fan Switch Replacement Service & Cost

What is the Thermo Coolant Fan Switch all about?

The cooling fan on your car only runs when the engine temperature is hot due to a thermo cooling fan switch. It is mounted on the engine and detects the temperature of the engine as a simple electrical two-wire switch. When the temperature reaches the set value for the switch, it completes a circuit inside that initiates the cooling fan operation. When the temperature drops below a set threshold, the cooling fan turns off. If the thermo cooling fan switch is faulty, the cooling fan may run all the time even if the engine is off, or the cooling fan may not turn on at all when the engine temperature is too high.

Keep in mind:

  • Your engine’s thermostat is vital for preventing overheating.
  • The cooling fan can continue to run even when the engine is shut off.

How it's done:

  • The coolant is allowed to cool and then drained
  • The defective thermo coolant fan switch electrical connector is detached from the switch and the switch removed.
  • The new thermo coolant fan switch is installed and the electrical connector is connected
  • The coolant is filled and coolant system is bled of air
  • The engine is ran and cleared of codes and road tested for proper cooling fan operation

Our recommendation:

The cooling fan switch will likely last the life of your vehicle, though it can fail unexpectedly as electrical components are prone to do. If that happens or if you suspect the thermo cooling fan switch is faulty, have one of our expert mechanics diagnose it.

What common symptoms indicate you may need to replace the Thermo Coolant Fan Switch?

  • Check Engine light is on
  • Cooling fan isn’t turning on
  • Engine temperature is above normal or the engine hot warning is on

How important is this service?

Because catastrophic engine failure can occur from overheating, it is important to replace the thermo cooling fan switch as soon as it has been diagnosed as faulty.

Brian
8 years of experience
Extremely knowledgeable and professional. He performed a pre-purchase inspection for me, and actually spent time the night before reading reviews on the type of car I was looking at. He did this to see if there were patterns of frequent problems with this model, in order to pay particular attention to those areas. He called me both before and immediately after the inspection. When calling before the inspection, he inquired as to any personal concerns I might have to help tailor his inspection. He provided immediate and thorough feedback with a very polite and friendly manner. His attention to detail was truly commendable. If I should ever need services again, I'll specifically request this man. With his professionalism and dedication to providing the utmost in service, I'd hire him personally if he were certified with the NASD (National Association of Securities Dealers). Seemed to be a great person and even better mechanic.
