What It Helps Fix

• Engine running too cool or taking too long to reach operating temperature
• Temperature swings caused by a sticking thermostat
• Coolant flow issues related to worn thermostat sealing surfaces
• Air trapped in the cooling system after thermostat service
• Improper temperature control in OE-specified 180°F applications

Installation Notes and Tips

• Verify the vehicle calls for a 180°F thermostat before installation.
• Inspect the thermostat housing and sealing surfaces for corrosion or damage.
