Description

DHD 500-304 Duramax Thermostat Housing to Heater Core Fitting 2004.5-07

DHD's Billet Coolant supply fitting replaces the OE steel EGR/heater core supply tube. This assembly is designed to fit into the front coolant bridge adjacent to the thermostat housing and is almost a must when doing a high flow intake install.

Confirmed fitment on LLY and LBZ trucks. May fit other years.

Note: Our fitting has been revised to work in conjunction with HSP's forward facing thermostat housing.
