Product Description

Anyone running one of Wehrli's fabricated coolant tanks eventually needs the matching sensor - whether it's for an initial install or replacing one that's failed after years of service. The WCF206-19 is built specifically to work with WCFab's coolant tank lineup, so it seats correctly and reads coolant level accurately rather than being a generic sensor forced into a spot it wasn't designed for.

It covers a broad span of Duramax generations, from early LB7/LLY/LBZ/LMM trucks through the current L5P, making it a straightforward parts-counter item to keep on hand for anyone maintaining a WCFab-equipped cooling system. If the low coolant warning light isn't behaving correctly on a truck with an aftermarket tank, this is the sensor built to fix it.
