Product Details
Four Seasons Temperature Switch 37437 is built for cooling fan temperature control in 1984-1986 Audi Coupe models. This switch monitors coolant temperature and signals the fan circuit when the engine reaches the specified threshold, helping maintain proper operating temperature. The Four Seasons Temperature Switch line focuses on OE-style replacement parts for thermal management systems, and this part cross-references A03837 and SW1637 for the same application.
Fits 1984-1986 Audi Coupe, N/A. The fitment notes specify a red switch located in the cylinder head, so matching the mounting location and connector style is important when replacing the original unit. Four Seasons 37437 is a practical choice when servicing an Audi Coupe cooling system that uses a temperature-actuated fan switch.
