WA01000LT
The WOD -16 AN LT Thermostat Housing is precision machined from 6061 billet aluminum to simplify coolant plumbing on GM Gen V LT engines while retaining proper thermostat operation. Designed for custom chassis, LT engine swaps, rock crawlers, Ultra4 race cars, prerunners, and high-performance street builds, this housing converts the factory coolant outlet to a clean, durable -16 AN connection.
Unlike many swap setups that eliminate the thermostat, this housing is designed to retain the factory LT thermostat. Maintaining thermostat operation helps the ECU properly manage coolant temperature, warm-up cycles, fuel delivery, ignition timing, and overall engine performance while giving builders the flexibility of AN-style coolant plumbing.

Fitment Notes:
Modern LT engines rely on coolant temperature data for proper ECU operation. Retaining the thermostat allows the engine to reach its intended operating temperature, improving warm-up, fuel control, ignition timing, and overall drivability.
No. The factory thermostat and gasket are sold separately unless otherwise specified.
This housing fits GM Gen V LT engines including LT1, LT2, LT4, LT5, L82, L83, L84, L86, L87, L8T, and other LT-based engine platforms.
-16 AN hose provides a clean, professional cooling system with flexible routing that is ideal for custom chassis, engine swaps, and race vehicles where molded factory hoses are difficult to package.
Yes. It is designed for severe-duty cooling systems found in rock crawlers, Ultra4 race cars, prerunners, rock bouncers, custom chassis builds, and high-performance street applications.
Billet 6061 aluminum offers excellent strength, corrosion resistance, and dimensional accuracy while providing a clean, professional appearance that stands up to demanding off-road environments.
