Details on the Molded Coolant Hose Product Line

The Gates Molded Coolant Hose line focuses on delivering hoses that are pre-formed to match specific vehicle cooling system layouts. This eliminates the need for bending or shaping during installation, reducing the risk of kinks or leaks. The molded construction of part number 22641 ensures a precise fit for the Jeep Grand Cherokee and Oldsmobile Aurora, maintaining optimal coolant flow and system integrity.

Technical Description and Specifications

This radiator coolant hose is made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and automotive fluids. The hose features a centerline length of 11.8 inches (381 mm), with both ends having an inside diameter of 1.53 inches (39 mm), providing a consistent diameter for smooth coolant passage. The absence of an internal spring allows the hose to remain flexible while preventing collapse under vacuum conditions. The molded design ensures the hose matches the exact contours required for the cooling systems of the Jeep Grand Cherokee and Oldsmobile Aurora.

Common Applications and Problem Solving

• Replacement of worn or cracked radiator coolant hoses in Jeep Grand Cherokee and Oldsmobile Aurora
• Resolving coolant leaks caused by hose deterioration or improper fit
• Preventing overheating issues due to restricted coolant flow
• Eliminating hose collapse under engine vacuum conditions
• Maintaining proper coolant circulation for engine temperature regulation

Installation Notes and Tips

Before installation, ensure the engine is cool and the cooling system is depressurized. Verify that the hose dimensions match the original part, focusing on the 1.53-inch inside diameter and 11.8-inch length. Use appropriate clamps to secure the hose ends without over-tightening, which can damage the EPDM material. The molded shape should align with the vehicle’s coolant routing to avoid kinks or stress points. Inspect the cooling system for any additional wear or damage during replacement.
