Detailed Product Description

The Gates Molded Coolant Hose 20630 is a radiator coolant hose crafted from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids. This hose features a molded construction, which provides a precise shape that matches original equipment specifications, ensuring a secure and leak-free connection. Both ends of the hose have an inside diameter of 1.5 inches (38 mm), making it suitable for radiator connections requiring this size. With a centerline length of 16 inches (406 mm), the hose is designed to fit specific coolant routing paths without the need for modifications.

This part is compatible with a range of vehicles including Chrysler 300, Dodge Challenger, Charger, D100, D200, D300, Ramcharger, and Mercury models such as Montego and Monarch. The molded design eliminates the need for additional clamps or fittings, simplifying installation and maintaining system integrity.
