2020-2025 Chevrolet GMC 6.6L L5P Duramax OEM Placement Coolant Tank Kit - WCFab Red

The Wehrli Custom Fabrication OEM Placement Coolant Tank Kit in striking WCFab Red. This fabricated aluminum reservoir installs directly in the factory location on the driver's side firewall, delivering reliable cooling performance that outpaces stock plastic tanks prone to cracking, yellowing, and sensor failures. Built to handle the demands of high-performance diesel applications, it ensures consistent coolant levels and prevents overheating issues common in heavy-duty towing and hauling scenarios. Drivers report fewer coolant warnings and longer intervals between maintenance compared to OEM setups or aftermarket alternatives that compromise on fit or durability.

  • Fabricated aluminum coolant tank with pre-installed billet aluminum sight glass for instant level checks.

  • Black anodized CNC-machined billet aluminum cap (two-prong locking mechanism, clear anodized version available separately).
  • Preformed rubber overflow hose for clean OEM-style routing.
  • All necessary mounting hardware for bolt-on installation using factory points.
  • Professional WCFab Red powder coating (two-coat process with clear topcoat for lasting finish, raw aluminum brushed tag standard).
