Admin Where is the cylinder head temperature sensor located?
The Ford Transit cylinder head temperature sensor, or CHT, is used in the same way an engine coolant temperature sensor is. Located next to the cylinder head toward the back of the engine block, it monitors the temp of the head and sends this data to the van’s main computer.
What is a cooling fan switch?
When the coolant reaches a specified temperature, this switch turns on the vehicle’s coolant fan, which draws air through the radiator to regulate engine temperature.
What does a cylinder head temperature sensor do?
Thermometrics Cylinder Head Temperature Sensor is designed to take the place of one of the cylinder head bolts on a diesel engine. The sensor’s purpose is to measure the cylinder head temperature and to signal the vehicle’s operator if an engine overheats (that is, if an engine over-temperature is taking place).
Where is the fan relay on a Chevy Silverado?
The fan relay is often located in the engine bay’s fuse box, but the best way is to check your repair manual to find where it is located. Testing a 4 pin relay is often very straightforward. Remove the relay and give 12 volts to pin 30 and 85.
What to do if your radiator fan control module fails?
As I talked about before, some cars have a separate control module for just the radiator fan control. This control module is often installed in the engine bay, exposed to heat and dust. This can make the control module to fail after a while because of corrosion. Locate the relay and check for any visual damages outside of it.
Why is my radiator fan not working on my Ford Ranger?
The ECU is responsible for starting the radiator fan once the engine gets hot. The ECU receives information from the temperature sensor which signals the ECU to initiate the fan. Therefore, if the temperature sensor is faulty, it is likely that the ECU is not receiving the proper signals and thus the fan is not working.
How do you test a radiator fan motor?
The radiator fans have electrical motors inside of them, which will wear out after some years. You can test the electrical radiator fans by taking a wire from the car battery, unplug the radiator fan connector, and put 12v+ and ground into the connector.
