Technical Description of Part Number 20351

This radiator coolant hose features an EPDM rubber composition, known for its resistance to heat, ozone, and coolant chemicals. The hose has two different inside diameters: 1.5 inches (38 mm) on one end and 1.75 inches (44 mm) on the other, accommodating specific radiator and engine connections. With a centerline length of 3.5 inches (89 mm), it is designed for compact routing in tight engine compartments. The molded design ensures dimensional stability and eliminates the need for additional spring reinforcement or quick connect fittings.

Common Applications and Issues Addressed

• Replacement of worn or cracked radiator coolant hoses in compatible vehicles
• Resolving coolant leaks caused by hose degradation or improper fit
• Preventing overheating due to compromised coolant flow
• Addressing hose swelling or softening from chemical exposure
• Ensuring secure coolant system connections without spring reinforcement

Installation Notes and Tips

When installing the Gates Molded Coolant Hose 20351, verify the hose end diameters match the radiator and engine fittings to ensure proper sealing. Use appropriate clamps rated for coolant hoses and avoid over-tightening to prevent hose damage. Inspect the surrounding components for wear or corrosion that may affect hose longevity. The molded design simplifies installation by providing a precise fit, but care should be taken to route the hose without kinks or sharp bends.
