Wehrli 01-07 Chevrolet 6.6L LB7/LLY/LBZ Duramax OEM Placement Coolant Tank Kit - Semi-Gloss Black

Wehrli Custom Fabrication is known for building robust parts for high-performance diesel trucks. This fabricated aluminum coolant tank kit is designed to replace the factory plastic reservoir on your 2001-2007 Chevrolet Silverado or GMC Sierra 2500/3500 HD with the 6.6L Duramax diesel engine. It mounts directly in the original location, making it a straightforward upgrade for your engine bay.

This kit swaps out the often-discolored and brittle factory plastic tank for a well-built aluminum one that’s finished in a durable semi-gloss black powder coat. It includes a convenient coolant level sight glass so you can easily check your fluid level at a glance, and a low coolant level sensor to alert you if it gets too low. The kit also comes with a black anodized billet aluminum cap and the necessary overflow hose and mounting hardware. It’s designed to fit stock trucks without needing any other modifications, using the factory mounting points for an easy installation with basic hand tools.

This kit is a great way to clean up the look of your engine bay while adding a more durable component. It replaces GM part numbers 15808714, 15290795, and 19353729.
