Detailed Product Overview

Standard Ignition RY-1758 is built to restore the open-and-close relay function that controls current flow to the coolant fan circuit. When the relay contacts wear or fail, the cooling fan may not cycle correctly, which can affect engine temperature management. This replacement relay is made with robust materials and a heat-resistant housing to handle demanding underhood conditions. It is a practical choice for Jeep Wrangler cooling system electrical repair, including 2009-2013 Jeep Wrangler and 2012-2013 Jeep Wrangler axle lock switch applications listed in the fitment data.

This part cross-references Carlson 16083 for the same application. Standard Ignition RY-1758 is also referenced by aftermarket numbers including 1R2486 and 56-2701.
