Standard Ignition RY-484 Engine Cooling Fan Motor Relay

Engine Cooling Fan Motor Relay for OE-Style Cooling Control

Standard Ignition RY-484 is an engine cooling fan motor relay built for 12-volt systems that need reliable fan control under hood. It uses a 5-blade terminal layout with a female square connector and 20 amp amperage rating for direct replacement service on select Saturn, Buick, and Pontiac applications.

Compatible With 2008-2010 Saturn Outlook, 2002-2004 Buick Rendezvous, and 2001-2002 Pontiac Aztek, this relay supports proper fan operation when the cooling system needs an electrical switching component that matches the original configuration. Standard Ignition RY-484 is also cross-referenced to Carlson 19271 for the same application.

Key Features

• Engine cooling fan motor relay for 12-volt vehicle electrical systems
• 20 amp amperage rating for cooling fan circuit control
• Female square connector with 1 connector interface
• 5 male blade terminals for OE-style fitment
• Composite housing helps protect against high temperatures and severe underhood conditions
• Brass or copper contacts are used where specified for wear resistance
• Manufactured under TS16949 and ISO9001 certified processes

Detailed Description

Standard Ignition RY-484 is an engine cooling fan motor relay designed to switch power to the cooling fan circuit in select GM-platform vehicles. It is built with a composite housing for heat resistance and durability, and the contact design uses brass or copper materials where specified to support long-term electrical performance. This part number, RY-484, is a direct-fit style replacement for 2008-2010 Saturn Outlook, 2002-2004 Buick Rendezvous, and 2001-2002 Pontiac Aztek cooling fan relay applications.

Standard Ignition manufactures ignition and electrical components with controlled production processes from component to finished part, helping ensure consistent fit and function for the intended vehicle application. If you are replacing a failed cooling fan relay on a Buick Rendezvous, Pontiac Aztek, or Saturn Outlook, RY-484 provides the correct terminal layout and electrical rating for the listed vehicles.

Common Problems This Relay Can Address

• Cooling fan not turning on when engine temperature rises
• Cooling fan running intermittently or only under certain conditions
• Relay-related overheating concerns caused by electrical switching failure
• Check engine or cooling system warnings tied to fan circuit faults
• Electrical contact wear in the cooling fan relay circuit

Installation Notes and Tips

Verify the connector shape, terminal count, and amperage rating before installation. Compare the original relay to Standard Ignition RY-484 to confirm the female square connector and 5-blade terminal layout match the vehicle harness. Inspect the relay socket for heat damage, corrosion, or loose terminals before installing the replacement.

For best results, diagnose the cooling fan circuit, fuse, and temperature control inputs before replacing the relay. This helps confirm the relay is the failed component and supports proper cooling fan operation after installation.

Quality Assurance

Standard Ignition builds this relay under TS16949 and ISO9001 certified manufacturing systems, with quality control maintained through the production process. The brand’s OE-focused electrical component background supports consistent part selection for the listed applications.
