About the Molded Coolant Hose Product Line

The Gates Molded Coolant Hose line focuses on molded radiator hoses that provide exact fitment and durability. These hoses are designed to meet OE specifications, offering consistent performance and resistance to heat, pressure, and coolant chemicals. The molded construction reduces the risk of leaks and hose failure, making it suitable for critical cooling system applications such as those in the Chrysler Caravan and Dodge Voyager.

Detailed Product Description

This radiator coolant hose, part number 22643, is made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and coolant fluids. The molded design ensures a precise fit with end diameters of 1.34 inches (34 mm) and 1.5 inches (38 mm), accommodating the specific hose connections in the cooling system. With a centerline length of 27.6 inches (701 mm), it matches the original equipment dimensions for proper routing and installation. The absence of an internal spring allows for unobstructed coolant flow, reducing the risk of blockages or flow restrictions.

Common Applications and Problem Solving

• Replacement of worn or cracked radiator coolant hoses in Chrysler Caravan and Dodge Voyager
• Prevention of coolant leaks caused by hose degradation or improper fit
• Restoration of proper coolant flow to avoid engine overheating
• Addressing hose swelling or softening due to heat exposure
• Eliminating coolant contamination from hose material breakdown

Installation Notes and Tips

Ensure the engine is cool before removing the old hose to prevent burns. Verify that the hose ends match the specified inside diameters (1.34 inches and 1.5 inches) for a secure fit. Use appropriate clamps to secure the hose without over-tightening, which can damage the EPDM material. Inspect adjacent components for wear or damage during installation to maintain overall cooling system integrity.
