How does the thermo coolant fan switch work?
This switch is configured to work based upon the temperature of the engine. As engine temperature rises to a specific threshold, the switch is activated powering on the coolant fan. The coolant fan will continue to run until the engine temperature cools down to a specific predetermined level.
Can a bad thermo fan switch cause overheating?
There are many other engine systems which are also indirectly affected by the operation of this switch, but in the context of this article we will focus on its relation to the operation of the coolant fan. Several symptoms may point to a bad or failing thermo coolant fan switch. 1. Engine overheating
Why is my engine cooling fan not working?
Your engine cooling fan, only runs when needed to help cool the engine. So, a engine cooling fan, relay or control circuit failure is bad news. Because, it can allow the engine to overheat. The engine coolant sensor or a separate engine temperature switch, is used to monitor engine temperature.
What are the symptoms of a bad coolant fan switch?
A common sign of a faulty switch, which can also be alarming, is that the switch will simply not turn the fans on at the predetermined temperature level resulting in engine heat climbing above what it should be in order to run effectively.
This switch is configured to work based upon the temperature of the engine. As engine temperature rises to a specific threshold, the switch is activated powering on the coolant fan. The coolant fan will continue to run until the engine temperature cools down to a specific predetermined level.
When does the thermostatic fan switch turn on?
The thermostatic fan switch turns on the electric fans when the engine has reached operating temperature. Before replacing the switch, check to see if the wiring harness is connected to the switch. Sometimes the wires fall off the switch or break causing the switch to not work and is usually misdiagnosed.
What does the thermo switch on a Honda radiator do?
If the fan switch relay is giving off the appropriate readings and is in working condition, move on to the next step. The thermo switch (also called the cooling fan switch) sends a signal to the cooling fan, so the fan turns on if the coolant gets too hot.
There are many other engine systems which are also indirectly affected by the operation of this switch, but in the context of this article we will focus on its relation to the operation of the coolant fan.
