Description

The Wehrli 100268-SC coolant tank kit is designed as an OEM replacement for 2020-2026 L5P Duramax trucks. It mounts in the factory coolant tank location on the driver's side firewall. The kit includes a fabricated aluminum coolant tank, a low coolant level sensor, a black anodized billet aluminum cap, an overflow hose, a coolant level sight glass, and installation hardware. It is available in various powder coat finishes and uses OEM mounting points for easy installation. This tank addresses common issues with factory L5P coolant level sensors by providing a serviceable thread-in style sensor. It is designed to enhance the under-hood aesthetics by replacing the factory plastic reservoir.
