Good To Know
Q: Why is the opening temperature critical for this thermostat? A: A 190°F thermostat ensures the engine reaches peak operating temperature quickly, which optimizes fuel efficiency and reduces internal wear. Using the correct rating is essential for the 6.7L ISB to run as designed.
Q: Does the thermostat come with a gasket or seal? A: This listing is for the thermostat with a pre-installed O-ring, which simplifies installation and helps maintain a leak-free seal. Always verify the gasket condition during installation.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
