Cooling System Maintenance | Tips & Tools

Premature Heater Core failure is often caused by poor Cooling System maintenance. Protect your engine and maximize system performance with simple preventative maintenance:

• Completely drain and flush the system using Cooling System Flush. Flushing the system is critical to prevent system contamination and failure.
• Consider replacing the Heater Hoses (and Hose Clamps), Thermostat and Radiator Cap as part of routine preventative maintenance. Rust and debris from degrading parts can clog the Heater Core and Radiator, and lead to costly engine damage.
• Refill Radiator with fresh Coolant / Antifreeze according to the volume and formula specified in your Owner's Manual. Inspect levels and condition every year.
