Gates 19942 HVAC Heater Hose - Heater (Lower) or Heater To Engine

Gates 19942 Molded Heater Hose Overview

The Gates 19942 molded heater hose is a factory-shaped coolant hose built for tight engine bays where a straight hose will not route correctly. Made from EPDM, it is sized with 19 mm (0.75 in) inside diameters at both ends and a 248 mm (9.78 in) centerline length for an OEM-style fit.

Compatible with 2012-2013 Buick Verano heater to engine routing and 2014-2017 Buick Verano heater (lower) routing, this molded heater hose supports coolant, water, and air transfer applications. The Gates Molded Heater Hose line is made for smaller, tighter-fitting engine compartments and is also approved for marine applications.
