Mr Gasket 6368 LS3 / LS6 Thermostat, 180 Degree

Mr. Gasket Thermostats eliminate the huge swings in coolant pressure that plague lesser thermostats at high rpm, when coolant temperature and pressure can battle for control of the thermostat and prevent it from opening at the designated temperature. Thermostat is compatible with LS Series engines with a separate thermostat and water neck, they open at 180 degrees every time, regardless of engine rpm, and their high-flow design and brass and copper construction eliminate the damaging effects of cycling when you're stuck in stop-and-go traffic. These thermostats work with '04 and up LS3 / LS6 and truck motors where the thermostat and housing are separate assemblies
