Single Switch Installation:
1. Place the cooling fan switch near the thermostat housing behind the distributor assembly on the left side of the engine. The switch wire color should be green and black.
2. Disconnect the wire terminal from the cooling fan switch.
3. Allow the engine coolant temperature to be close to 196-203°F (91-95°C).
4. Use an ohmmeter or suitable connectivity tester to check the connectivity between the switch terminals of both fans. The fan switch should be on (switch closed) at the above temperature. When the temperature drops 5 to 15 °F (3 to 8 °C) from the temperature at which the switch is first turned on (switch closed), the switch should not be turned on (off).
5. If the switch does not operate according to the information provided, allow the engine to cool below 100 °F (37 °C) and replace the switch.
Wiring Note: For two red wires, connect the long red wire to the fan and the short red wire to the battery.
1. Install the relay as easily as possible under the hood, near the fan.
Note: Do not use PTFE tape or thread compounds on thermostats or adapters. For proper operation, the thermostat must be grounded to the engine via a wire, and the engine must be grounded.
2. Install the thermostat in the intake manifold or cylinder head. Connect the black wire to the thermostat and cut it to the appropriate length.Crimp the red terminal onto the black wire and connect it to the thermostat.
3. Route the red wire and connect it to the "+" terminal of the fan or to the fan motor power cord marked "to electric fan".
4. Install the supplied circuit breaker in a convenient location as close as possible to the power supply you are using for the fan relay (battery or large terminal on the starter solenoid).
5. Carefully route the red wire from the relay to the side circuit breaker installed in the stairwell. Cut it to the appropriate length and install it using small yellow ring terminals. Use another small yellow ring terminal to pull the remaining red wire and connect the unused terminal of the circuit breaker to the battery source. This wire is marked "Connect to Battery/Constant Heat".
6. Connect the brown wire to the ignition switch or the fan switch (choose the most convenient method).
Installation Note:
1. Turn off the engine and replace the new cooling fan temperature switch when the water in the engine radiator has cooled to room temperature.
2. Avoid high external heat sources after installation.
3. Avoid spilling water on surrounding car parts during installation.

Package List:

1 x Electric Cooling Fan Thermostat Kit (17 pieces)

Note:

Placing the electric cooling fan switch inside the threads may damage the component. This test should be performed with coolant, as water has a boiling point lower than the temperature required by some sensors. Please perform this process in a safe, well-ventilated area. Do not inhale the mist produced by the heating coolant. Wear safety glasses and avoid touching any heated components. Do not use any open flame heaters.
