  • L83 Thermostat

    Hey guys,

    I have been searching for the proper thermostat for the new L83 Ecotec3. From what I understand it may be a different design than the old Gen IV. I seek a 160 degree stat. Any information would be greatly appreciated.

    The Lingenfelter Performance Engineering low temperature thermostats for the new GM direct injection Gen V V8 and V6 engines are designed to reduce engine operating temperature, increasing engine performance. They are a direct fit replacement for the OEM 212 degree F (100 degree C) thermostat.

    The LPE low temperature thermostats are available in three temperature ranges. The 160 degree F version is recommended for racing and marine applications. The 170 degree F is recommended for high performance street vehicle applications. The 180 degree F is recommended for high performance applications that also want to maintain better heater performance in the winter time usually truck and SUV applications.

    Note that the Gen V engines have the thermostat assembly on the hot side or engine out side of the cooling system loop so 170 degree thermostat in the Gen V engine is more similar to a 160 degree thermostat in a Gen III or IV engine where the thermostat was on the cold side or engine inlet side of the cooling system loop.

    - Engine and chassis dynamometer verified performance
    - Direct replacement for the OEM thermostat
    - Fits in the OEM thermostat housing
    - Reduced engine operating temperature (when in thermostat and not fan or airflow limited control)
    - Increased power
