Technical Specifications

Installation Guide

The GATES 3918 Radiator Hose is designed for straightforward installation:

1. Preparation: Ensure the engine and cooling system are cool. Drain coolant if necessary to avoid spills.
2. Remove Old Hose: Carefully detach the existing hose from both the radiator and water pump or heater core connections, noting any fittings or clamps used.
3. Fit the New Hose: Slide the GATES 3918 onto the radiator outlet first, then secure it to the water pump or heater core. Use the appropriate hose clamps to maintain a tight seal.
4. Check for Leaks: Refill the cooling system with fresh coolant and start the engine. Observe all connections for any signs of leakage over a short test run.

Benefits of EPDM Construction

EPDM rubber offers several advantages critical to automotive cooling systems:

• Heat Resistance: Maintains flexibility and structural integrity up to 120 °C, preventing cracking or hardening under high engine temperatures.
• Chemical Stability: Resistant to coolant additives, antifreeze, and other chemicals commonly found in automotive fluids.
• Longevity: Exhibits excellent resistance to ozone, UV light, and weathering, extending the service life of the hose even under harsh operating conditions.

Maintenance Tips

To preserve optimal performance of your GATES 3918 Radiator Hose, follow these simple maintenance practices:

• Regular Inspection: Check for visible signs of wear, bulging, or cracks during routine vehicle inspections.
• Coolant Quality: Use the recommended coolant type and maintain proper coolant levels to prevent overheating and corrosion.
• Avoid Over‑Pressurization: Ensure the cooling system’s pressure relief valve is functioning correctly to avoid excessive pressure that could damage hoses.
