This direct-fit replacement sensor monitors coolant temperature and sends accurate electrical signals to your dashboard gauge, ensuring reliable temperature readings for optimal engine management.

Key Features:

• Factory-calibrated thermal switch with bimetallic contact arm for precise temperature sensing
• Custom wax formulation that expands when heated to activate snap-action electrical contact
• 2-terminal blade connector design with rectangular female connector and male terminals
• All units calibrated and tested to confirm switch actuation at specified temperature set point
• Robust design with high-grade materials meets OEM specifications for maintenance-free operation
• Direct-fit attachment method for easy installation

Standard Motor Products maintains complete quality control throughout the manufacturing process, from componentry to finished product. Each thermal switch undergoes rigorous factory calibration to ensure electrical contact occurs at the precise lower-temperature set point. The bimetallic contact design uses different expansion rates of two fused metals to provide reliable, creep-action performance that service professionals depend on.
