Wehrli 2020+ Chevrolet 6.6L L5P Duramax Upper Coolant Pipe - WCFab Red
Protect and upgrade the coolant system on your 2020+ Chevrolet Silverado HD or GMC Sierra HD with the Wehrli Custom Fabrication Upper Coolant Pipe in WCFab Red for the 6.6L L5P Duramax. This precision-fabricated aluminum coolant pipe replaces the factory upper coolant tube, offering superior durability and heat resistance to prevent the cracking, swelling, or coolant leaks that can plague OEM components over time.
Wehrli fabricates the upper coolant pipe from welded aluminum with precision-machined fittings that accept the factory coolant hoses directly. The WCFab Red powder coat provides a clean, polished finish that looks great in the engine bay and resists the high temperatures associated with diesel engine coolant systems. A straightforward upgrade that adds peace of mind and a custom appearance to your 2020+ Duramax.
