Installation Guide

1. Preparation: Allow the engine to cool completely. Drain a small amount of coolant if necessary to relieve pressure.
2. Remove Old Cap: Unscrew the existing radiator cap by turning it counterclockwise until it releases from the radiator neck.
3. Inspect Gasket: Check the rubber gasket for wear or damage. Replace if any signs of cracking are present.
4. Apply New Cap: Place the Gates RC125 Radiator Cap onto the radiator neck, aligning it with the threads.
5. Tighten Securely: Turn the cap clockwise until snug. Avoid overtightening to prevent thread damage.
6. Recheck Pressure: After reassembly, start the engine and monitor the pressure gauge to confirm proper sealing.

Maintenance Tips

• Inspect the cap regularly for signs of corrosion or wear.
• Replace the gasket every 2–3 years or sooner if it shows deterioration.
• Avoid using high-temperature coolant that exceeds the recommended specifications, as this can compromise seal integrity.
