Overview

The Standard Ignition RY-1781 is an engine cooling fan motor relay designed for consistent electrical control of your vehicle's cooling fan system. It features a square connector shape and four male blade terminals for a secure, precise fitment. This 12-volt relay operates to regulate the cooling fan motor, ensuring proper function to prevent overheating.

It addresses common issues such as intermittent or non-functioning cooling fans, engine overheating, and electrical faults related to the cooling fan circuit. Installation involves ensuring the ignition is off and the battery is disconnected, then verifying the connector and terminals align correctly with the vehicle's wiring harness.
