About the Molded Coolant Hose Product Line

The Gates Molded Coolant Hose line focuses on delivering hoses that are pre-formed to exact specifications, reducing installation time and improving sealing performance. This molded design helps maintain consistent coolant flow and reduces the risk of leaks compared to universal or flexible hoses. The 21732 part benefits from this product line's emphasis on precision fitment and material durability.

Detailed Product Description

This radiator coolant hose is made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and automotive fluids, making it suitable for long-term use in engine cooling systems. The molded construction ensures the hose maintains its shape and fits securely between radiator connections. With end diameters of 1.25 inches (32 mm) and 1.38 inches (35 mm), and a centerline length of 34.8 inches (884 mm), the hose matches the original equipment specifications for the listed Dodge and Plymouth models. The absence of an internal spring allows for unobstructed coolant flow, reducing the chance of blockages or pressure drops.
