5. Setup and Installation
Detailed, step-by-step installation instructions are included with your Generac 5616 Extreme Cold Weather Kit. It is crucial to follow these instructions precisely. The installation process typically involves both mechanical and electrical procedures.
5.1. General Installation Steps (Overview)
- Preparation: Ensure the generator is completely powered off, cooled down, and isolated from all fuel and electrical sources.
- Coolant Drainage: Partially drain the engine coolant to allow for hose connections.
- Block Heater Mounting: Install the block heater into the designated port on the engine block. This often involves threading an adapter nipple and ensuring proper orientation for hose connections.
- Hose Connections: Connect the heater hoses between the block heater and the engine's cooling system. Secure all connections with appropriate clamps.
- Electrical Wiring: Connect the block heater to a dedicated electrical circuit. The heater typically draws approximately 1500 watts and requires a 20-amp breaker with 12-gauge wiring. Ensure all electrical connections are secure and weatherproof.
- Coolant Refill: Refill the engine coolant to the proper level, bleeding any air from the system as per the generator's manual.
- Testing: After installation, carefully test the system according to the provided instructions to ensure proper function and no leaks.
Important: Refer to the specific installation manual provided with your kit for detailed diagrams, torque specifications, and safety warnings. If you are not comfortable performing these steps, contact a qualified Generac service technician.
6. Operation
Once installed, the Generac 5616 Extreme Cold Weather Kit operates automatically to maintain optimal engine temperature. The block heater is typically thermostatically controlled, meaning it will activate and deactivate based on the engine's temperature.
- Automatic Function: The heater will turn on when the engine temperature drops below a preset threshold (e.g., approximately 80°F or 27°C) and turn off when it reaches a higher preset temperature (e.g., approximately 100°F or 38°C). These temperatures may vary slightly.
- Purpose: The primary function is to keep the engine block warm, preventing cold-start issues and reducing wear on engine components during very cold weather.
- Power Consumption: The heater consumes electrical power when active. Ensure the dedicated circuit is capable of handling the load.
No user intervention is typically required for the operation of the cold weather kit once correctly installed.
7. Maintenance
Regular maintenance of your Generac 5616 Extreme Cold Weather Kit ensures its continued reliability and performance. Always perform maintenance with the generator powered off and cooled.
- Visual Inspection: Periodically inspect all hoses, clamps, and electrical wiring for signs of wear, damage, or leaks. Replace any compromised components immediately.
- Coolant Level: Check the engine coolant level regularly as part of your generator's routine maintenance. Ensure it is at the recommended level.
- Electrical Connections: Verify that all electrical connections to the block heater are secure and free from corrosion.
- Generator Manual: Adhere to the maintenance schedule outlined in your Generac standby generator's owner's manual, as the cold weather kit is an integral part of the system.
8. Troubleshooting
If you encounter issues with your Generac 5616 Extreme Cold Weather Kit, consider the following troubleshooting steps. For complex problems, contact a qualified service technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Heater not turning on. | No power to the circuit; tripped breaker/GFCI; ambient temperature above activation threshold; faulty heater element. | Check circuit breaker and GFCI. Verify power supply. Ensure ambient temperature is low enough for activation. If power is present and temperature is low, heater may be faulty; contact service. |
| GFCI (Ground Fault Circuit Interrupter) trips repeatedly. | Electrical leak in heater element or wiring; moisture ingress. | Immediately disconnect power. Inspect wiring and heater for damage or moisture. This indicates a serious electrical fault; contact a qualified electrician or service technician. |
| Coolant leak around heater or hoses. | Loose hose clamps; damaged hose; improper seal at heater connection. | Tighten hose clamps. Inspect hoses for cracks or damage and replace if necessary. Ensure heater connection is properly sealed. Refill coolant as needed. |
Always prioritize safety. If you are unsure about any troubleshooting step, consult a professional.
