WA01000LS
The WOD -16 AN LS Thermostat Housing is designed to simplify coolant plumbing on GM LS engines while retaining proper thermostat operation. Precision machined from billet aluminum, it converts the factory coolant outlet to a clean -16 AN connection, making it ideal for LS swaps, tube chassis builds, rock crawlers, Ultra4 race cars, rock bouncers, and custom performance vehicles where space and hose routing are critical.
Unlike many swap setups that eliminate the thermostat, this housing is engineered around the OEM 1997–2008 Corvette LS thermostat and gasket. Retaining the thermostat helps maintain proper engine warm-up, ECU coolant temperature management, drivability, and consistent cooling performance while allowing the use of AN-style coolant plumbing.

Fitment Notes:
The engine control module uses coolant temperature during warm-up to manage fueling, ignition timing, idle quality, and other operating parameters. Retaining a properly functioning thermostat helps the engine reach and maintain its intended operating temperature for consistent drivability and cooling performance.
No. The thermostat and gasket are sold separately unless otherwise specified.
This housing is designed around the OEM 1997–2008 Corvette LS thermostat and gasket.
Yes. It fits virtually all GM LS-based engines, including LS1, LS2, LS3, LS6, LQ4, LQ9, LM7, LR4, L33, and other LS-family engines.
-16 AN hose provides a clean, professional cooling system with flexible routing options that are ideal for custom chassis, race cars, and LS swap projects where molded factory hoses are difficult to package.
Yes. It has been designed for high-performance street vehicles, rock crawlers, Ultra4 race cars, rock bouncers, prerunners, and custom tube chassis builds that require reliable AN-style coolant plumbing.
