Wehrli 06-10 Duramax LBZ/LMM Thermostat Housing Kit - Bengal Blue

This is the Wehrli Custom Fabrication Thermostat Housing and Upper Coolant Pipe Kit, designed specifically for 2006-2010 Duramax LBZ and LMM trucks. It replaces the stock upper radiator hose and coolant return pipe, rerouting coolant flow upwards and forward. This updated layout makes it much easier to get to the driver's side fuel system components, which is a big help during maintenance or upgrades. It also creates more room in the engine bay, which is especially useful if you're planning to install larger aftermarket turbochargers, like the race cover or SXE styles.

The housing itself is CNC machined from solid billet aluminum, giving it a strong and well-built foundation. This kit includes the necessary coolant pipe, silicone boots, and t-bolt clamps to complete the installation. It's designed to work with factory VGT-style turbochargers, but also accommodates larger aftermarket options. The Bengal Blue powder coat finish not only looks sharp but also adds a layer of protection. This kit is a popular choice for Duramax owners looking to clean up their engine bay, improve access for other modifications, and update the overall look of their truck.

This kit is a direct replacement for several GM part numbers, including 19330105, 15792824, 25833204, and 97361881. It's available for both single and twin CP3 fuel pump setups, so be sure to select the correct part number for your application. The updated coolant routing can also be beneficial for overall engine cooling system efficiency.
