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, making it suitable for long-term use in automotive cooling systems. The dual inside diameter design (1 1/4 inch on one end and 1 9/32 inch on the other) allows for a secure connection between different sized radiator components. The hose’s black color matches OEM standards, and its 15 1/4 inch trunk height ensures proper fitment without interference. It does not include a heat shield or protective sleeve, so installation should consider surrounding heat sources.
