Wide Open Design’s -16 LS Thermostat Housing makes plumbing your LS cooling system simple, clean, and reliable, especially in tight tube chassis or custom swap applications.

Any fuel injected LS engine relies on coolant temperature data for proper ECU function. Removing the thermostat can negatively impact warm up cycles, drivability, and engine management. That’s why we designed this housing to work with an OEM-style thermostat- just like GM intended.

This housing is designed around the OEM 1997–2008 Corvette LS thermostat and gasket, allowing you to retain factory function with upgraded plumbing capability.

If you need a thermostat, this housing works perfectly with:
