OER 14091278 Features:

This molded 3/4" heater hose connects the heater valve to the water pump and oil cooler line on 1985-87 Corvette models with the oil cooler KC4 option. The KC4 option can be identified on the Corvette models by the oil filter adapter. If the oil filter screws into an oil cooler with an inlet and an outlet pipe that is mounted to the engine block, you have the KC4 option. If the oil filter screws directly into the engine block, you do not have the KC4 option.
