5. Setup & Installation
Proper installation is crucial for the safe and effective operation of your engine heater. If you are not confident in your mechanical abilities, it is recommended to seek professional installation.
General Installation Steps:
- Identify Installation Location: The heater should be installed in a lower radiator hose or another suitable location in the engine's cooling system where it can effectively circulate heated coolant. Ensure there is enough space for the unit and its mounting bracket, and that the power cord can reach a grounded outlet without strain.
- Drain Coolant: Partially drain the engine's cooling system to a level below the intended installation point. Collect coolant in a suitable container for proper disposal or reuse.
- Cut Heater Hose: Carefully cut the selected heater hose to create a gap for the heater unit. Ensure the cut is clean and straight.
- Install Heater In-Line: Insert the heater unit into the cut hose sections. Use the provided Y-fitting or threaded adapter if necessary to ensure a secure and leak-free connection. The arrow on the heater unit typically indicates the direction of coolant flow.
- Secure Connections: Use the provided hose clamps to firmly secure the heater unit to the coolant hoses. Tighten clamps sufficiently to prevent leaks, but do not overtighten.
- Mount Heater Unit: Attach the mounting bracket to the heater unit and secure the bracket to a stable, non-moving part of the vehicle's chassis or engine bay. Ensure the heater is positioned to avoid contact with hot or moving engine components.
- Refill Coolant and Bleed Air: Refill the cooling system with the appropriate coolant mixture. Start the engine and allow it to reach operating temperature with the heater on (if possible) to circulate coolant and bleed any trapped air from the system. Check coolant levels and top off as needed.
- Final Inspection: Visually inspect all connections for leaks. Ensure the power cord is routed safely and securely, away from heat, sharp edges, and moving parts.

6. Operating Instructions
Operating the All States Kat's External Tank Engine Heater is straightforward once installed correctly.
- Connect to Power: Plug the heater's power cord into a grounded 120V AC electrical outlet. Ensure the outlet is in good condition and capable of handling the 7 Amp load.
- Automatic Operation: The heater is thermostatically controlled. It will automatically activate when the coolant temperature drops below approximately 135 degrees Fahrenheit and will shut off when the temperature reaches approximately 175 degrees Fahrenheit. This ensures optimal engine temperature without continuous operation.
- Pre-heating Duration: For best results, plug in the heater several hours before you intend to start your vehicle, especially in extremely cold conditions. A typical pre-heating time is 2-4 hours, but longer durations may be beneficial in severe cold.
- Disconnect After Use: Always unplug the heater from the power source before starting the vehicle or performing any work on the engine.
7. Maintenance
Regular inspection and basic maintenance will help ensure the longevity and safe operation of your engine heater.
- Inspect Power Cord: Periodically check the power cord for any signs of damage, fraying, cuts, or exposed wires. Replace the cord immediately if damage is found.
- Check Hoses and Clamps: Inspect the coolant hoses connected to the heater for cracks, leaks, or deterioration. Ensure all hose clamps are tight and secure.
- Monitor Coolant Level: Regularly check your engine's coolant level and ensure it is at the manufacturer's recommended level. Low coolant can lead to heater malfunction or engine damage.
- Clean Unit: Keep the exterior of the heater unit clean and free of excessive dirt, grease, or debris. Do not use harsh chemicals or abrasive cleaners.
- Storage: If storing the vehicle or heater for an extended period, ensure the heater is unplugged and the power cord is neatly coiled and secured.
8. Troubleshooting
If you encounter issues with your All States Kat's External Tank Engine Heater, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater not warming engine | No power to the unit | Check power outlet, circuit breaker, and power cord connection. Ensure the outlet is live. |
| Insufficient operating time | Allow more time for the heater to warm the coolant, especially in very cold conditions. | |
| Air pocket in cooling system | Bleed air from the cooling system. Ensure coolant level is correct. | |
| Faulty heater element or thermostat | If other solutions fail, the unit may be defective. Contact support. | |
| Coolant leak at heater connections | Loose hose clamps or damaged hoses | Tighten hose clamps. Inspect hoses for cracks or damage and replace if necessary. |
| Improper installation | Review installation steps. Ensure fittings are correctly seated and sealed. | |
| Power cord gets hot | Overloaded circuit or damaged cord | Ensure the circuit can handle the load. Discontinue use immediately if the cord is hot to the touch and inspect for damage. Replace if damaged. |
