Detailed Product Overview

This cooling fan switch is designed to monitor coolant temperature and trigger fan operation based on the vehicle’s cooling system requirements.

Common Problems It Can Address

• Cooling fan not switching on at the proper temperature
• Cooling fan running inconsistently or cycling incorrectly
• Temperature-related overheating concerns tied to switch failure
• Damaged connector or worn electrical terminals at the switch
• Incorrect thread or connector match during cooling system repair

Installation Notes and Tips

Verify the 22MM x 1.50 thread size and square connector style before installation. Confirm the vehicle is not equipped with 2 Stage Cooling on 1992-1994 Saab 9000 applications, since that configuration is excluded from fitment. Inspect the harness, terminals, and connector condition during replacement to ensure a secure electrical connection.
