What This Switch Helps Address

• Cooling fan operation that does not trigger at the correct temperature
• Temperature signal issues caused by a worn or inaccurate coolant switch
• Hard-to-diagnose overheating concerns tied to fan control input
• Electrical resistance problems from aging sensor contacts
• Factory connector fitment problems during replacement service

Installation Notes and Tips

Confirm the connector style, threaded size, and application before installation. This part uses a threaded M14 x 1.4 design with a rectangular connector, so matching the original sensor configuration is important for proper fitment on BMW 740i, BMW 740iL, Audi S6, and related applications. Clean the mounting area before removal and transfer the electrical connection securely to the new switch.
