- Inspect all connections for leaks.
- Run the engine to operating temperature and re-check coolant levels and for leaks.
Note: This radiator does not include provisions for a transmission cooler or engine oil cooler. If your application requires these, external coolers must be used.
Operating Guidelines
Once installed, the Griffin MaxCool radiator operates as part of your vehicle's cooling system. Monitor your engine's temperature gauge regularly to ensure proper cooling performance.

Maintenance
Regular maintenance will extend the life and efficiency of your Griffin radiator.
Routine Checks:
- Visual Inspection: Periodically inspect the radiator for any signs of leaks, damage to fins, or corrosion.
- Cleanliness: Keep the radiator fins clean and free of debris (leaves, insects, dirt) to ensure optimal airflow. Use low-pressure air or water to clean the fins from the back side if possible.
- Hose and Clamp Inspection: Check all hoses for cracks, swelling, or hardening, and ensure clamps are tight.
- Coolant Flush: Follow your vehicle manufacturer's recommendations for coolant flush intervals.
Do not use harsh chemicals or abrasive tools for cleaning, as this can damage the aluminum fins.
