Universal Electric Radiator Cooling Fan Thermostat Temp Sensor Switch User Manual

Brand: American Volt | Model: AV-1022

1. Ro-ràdh agus Toradh Tharview

This manual provides detailed instructions for the installation, operation, and maintenance of your American Volt Universal Electric Radiator Cooling Fan Thermostat Temp Sensor Switch. This product is designed to automatically control electric cooling fans in automotive applications based on engine or fluid temperature.

The kit includes two temperature sensor switches, each featuring a brass thread-in probe compatible with 3/8" and 1/2" NPT threaded ports. The switch is engineered to activate (ground) the cooling fan when the temperature reaches 180°F and deactivate it when the temperature drops to 165°F, ensuring optimal engine cooling.

4. Setup agus Stàladh

Proper installation is crucial for the correct operation of the temperature sensor switch. Always disconnect the vehicle's battery before beginning any electrical work.

4.1. A’ taghadh àite stàlaidh

The sensor can be threaded into any suitable 1/2" NPT port that accurately reflects the temperature of the fluid you wish to monitor. Common locations include:

  • Bloc einnsean
  • Radiator (in-tank or hose adapter)
  • In-ghabhail iomadachaidh
  • Ionad uisge

Ensure the chosen location allows the brass probe to be fully immersed in the fluid for accurate temperature readings. If your port is 3/8" NPT, use the provided adapter.

4.2. Stàladh meacanaigeach

  1. Ensure the engine and cooling system are cool to prevent burns.
  2. Drain a small amount of coolant if installing directly into the cooling system to prevent spills.
  3. Apply a suitable thread sealant (e.g., PTFE tape or liquid thread sealant) to the threads of the sensor probe.
  4. Carefully thread the sensor into the chosen port. Do not overtighten, as this can damage the sensor or the port. Tighten until snug and leak-free.
  5. Refill any drained coolant and check for leaks.

4.3. Uèirleadh dealain

The sensor switch operates by providing a ground signal to activate a relay, which in turn powers the electric cooling fan. Refer to the wiring diagram below for proper connections.

Wiring diagram for electric cooling fan thermostat switch

Image 4.2: Typical Wiring Diagram for Electric Cooling Fan Thermostat Switch. This diagram illustrates how to connect the temperature sensor switch to a relay, circuit breaker, battery, and the electric fan for automatic operation.

  1. Connect to Sensor: Use the provided insulated female wire connectors to attach a wire to the single terminal on the temperature sensor switch.
  2. Connect to Relay: Connect the other end of this wire to the appropriate terminal on your fan relay (typically pin 85 or the coil ground terminal).
  3. Power and Fan Connections: Follow the relay manufacturer's instructions for connecting the relay to the battery (via a circuit breaker), ignition/fan switch (if applicable), and the electric cooling fan. Ensure all connections are secure and properly insulated.
  4. Bun-stèidh: Ensure the fan and battery have proper chassis grounds. The sensor switch provides a ground signal to the relay.

Cudromach: Always use an appropriately rated circuit breaker or fuse in the main power line to protect the circuit.

5. Stiùireadh Obrachaidh

Once properly installed and wired, the American Volt temperature sensor switch operates automatically. There are no user-adjustable settings.

  • When the fluid temperature reaches approximately 180°F (82°C), the sensor switch will close its internal contacts, providing a ground signal to the connected relay. This will activate the electric cooling fan.
  • The cooling fan will continue to run until the fluid temperature drops to approximately 165°F (74°C). At this point, the sensor switch will open its contacts, interrupting the ground signal and deactivating the cooling fan.

This cycle will repeat as necessary to maintain the desired operating temperature range for your cooling system.

6. Cumail suas

The American Volt temperature sensor switch is designed for long-term, maintenance-free operation. However, periodic checks can help ensure continued reliability:

  • Sgrùdadh lèirsinneach: Periodically inspect the sensor and its wiring for any signs of corrosion, damage, or loose connections.
  • Aodion lionn: Check around the sensor's threaded connection for any signs of coolant or fluid leaks. Tighten if necessary, but do not overtighten.
  • Ceanglaichean dealain: Ensure the female wire connector remains securely attached to the sensor terminal.
  • Glaineachd: Keep the sensor and surrounding area free of excessive dirt, grease, or debris.

7. A ’dèanamh trioblaid

If your electric cooling fan is not operating as expected with the temperature sensor switch, consider the following troubleshooting steps:

TrioblaidAdhbhar a dh’fhaodadh a bhith annFuasgladh
Fan does not turn on at 180°FNo power to relay; Faulty relay; Open circuit in wiring; Sensor not reaching temperature; Faulty sensorCheck circuit breaker/fuse; Test relay operation; Inspect all wiring connections (refer to Image 4.2); Verify engine/fluid temperature with a separate gauge; Test sensor continuity (should show continuity when hot); Replace faulty component.
Bidh fan a ’ruith gu leantainneachSensor stuck closed (grounded); Wiring shorted to ground; Faulty relayDisconnect sensor wire from relay; if fan stops, sensor is faulty. If fan continues, check wiring for shorts or replace relay.
Leughaidhean teòthachd neo-mhearachdachSensor not fully immersed in fluid; Air pocket around sensor; Incorrect sensor typeEnsure sensor probe is fully submerged; Bleed cooling system to remove air; Verify correct sensor for application.
