This hose does not fit Corvettes with the KC4 Oil Cooler option.
Our molded Corvette coolant heater hoses are made to OEM specifications to provide an easy direct installation and are manufactured in the USA with materials sourced from North America to provide quality.
This is the upper molded 3/4" hose on the heater core. The 3/4" hose connects the heater core to the water pump fitting and branches to the 5/16" small coolant vapor pipe. All fitments are correct to the original Corvette.
