Wehrli 06-10 Duramax LBZ/LMM Thermostat Housing Kit - Illusion Blueberry

The Top Outlet Billet Thermostat Housing and Upper Coolant Pipe Kit for 2006-2010 LBZ/LMM Duramax replaces the OEM upper radiator hose that normally crosses over the driver side valve cover as well as the coolant return pipe. By changing the coolant routing to an upwards and forward layout from the thermostat, this kit improves access to driver side fuel system components, adds room for larger aftermarket turbochargers, and updates engine bay appearance. Options available for single (P/N WCF100420) or twin CP3 setups (P/N WCF100424) in your choice of custom powder coat finishes. - - Replaces the following GM Part Numbers: 19330105, 15792824, 25833204, 97361881 Wehrli Custom Fab Thermostat Housing Kit, 2006-2010 Duramax LBZ/LMM, Illusion Blueberry IF YOU HAVE A DUAL WCFAB DUAL CP3 KIT OR A DUAL ALTERNATOR TRUCK, USE KIT NUMBER WCF100424.
