Standard Motor Products RY-1781 Engine Cooling Fan Motor Relay

The Standard Motor Products RY-1781 is an engine cooling fan motor relay designed to control the operation of your vehicle's radiator cooling fan. This relay serves as an electrical switch that allows low-current signals from the engine control module to safely control the higher-current cooling fan motor, ensuring proper engine temperature regulation.

Quality Engineering and Testing:

• 100% tested during manufacturing for electronic component assembly and wire bond connectivity
• Copper terminals with aluminum inlay maintain low electrical resistance while providing excellent wire bonding and corrosion protection
• Circuitry engineered to withstand electrical over-stress conditions including reverse polarity, ESD transients, and jump start voltage extremes
• 100% tested prior to shipping for continuous current load, quiescent current, voltage drop, pull-in current, voltage, and hysteresis
• Constructed with durable electro-magnets enclosed in high-temperature housing for resilience in harsh engine bay conditions

Standard Motor Products relays are manufactured to match OE specifications for fit, form, and function, providing a direct-fit replacement that restores proper electrical operation. As a trusted automotive aftermarket supplier since 1919, Standard Motor Products delivers reliable relay solutions backed by rigorous quality control testing.
