Product Description and Specifications

This radiator coolant hose is made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and coolant chemicals, which helps maintain hose integrity over time. The hose features two different inside diameters—1 3/8 inches on one end and 1 1/2 inches on the other—allowing it to connect different sized fittings within the cooling system. The black color matches OEM standards, and the hose does not include a heat shield or protective sleeve. It complies with SAE J20R4 Class D-1 and SAE J1684 Type EC specifications, ensuring it meets industry requirements for coolant hoses. The 14-inch trunk height supports proper routing and fitment in the specified vehicle models.
