Gates 18147 HVAC Heater Hose - Filler Pipe To Radiator

Gates 18147 Molded Heater Hose Overview

The Gates 18147 molded heater hose is a factory-shaped coolant hose built for tight engine bays and OE-style routing. It is a direct fit for 2006-2011 Honda Civic filler pipe to radiator applications and is formed from EPDM for use in coolant, water, and air service.

As part of the Gates Molded Heater Hose line, this hose is made for smaller, tighter-fitting engine compartments where a straight hose will not follow the original path. For Honda Civic cooling system service, the 18147 helps restore the correct molded route between the filler pipe and radiator.
