Wehrli 01-05 Chevrolet 6.6L LB7/LLY Duramax Thermostat Housing & Upper Coolant Pipe Kit - Bengal Red

Starting with a CNC machined billet aluminum thermostat housing, this Wehrli kit for your 2001-2005 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with a 6.6L LB7 or LLY Duramax engine offers a significant upgrade over the stock setup. It replaces the factory upper radiator hose and coolant return pipe, rerouting coolant flow upwards and forward. This updated routing not only makes accessing the driver-side fuel system components much easier but also creates additional space, which is crucial if you're planning to install larger aftermarket turbochargers, especially the race cover or SXE style.

Beyond the practical benefits for maintenance and upgrades, this kit also updates the look of your engine bay with a custom Bengal Red powder coat finish. It's designed to work with both single and dual CP3 pump setups, as well as factory VGT style turbochargers. The kit includes the coolant pipe, necessary silicone boots, and t-bolt clamps, ensuring you have the essential components for installation. This is a well-built piece that addresses common needs for Duramax owners looking to optimize their cooling system and engine bay layout.
