FAE 36110 Switches

FAE 36110 Switches

The FAE 36110 Switch is a precision temperature‑controlled relay designed to manage the operation of radiator fans in automotive applications. It combines robust construction with reliable thermal sensing, ensuring that cooling systems maintain optimal performance across a wide range of operating conditions.

Key Functional Features

• Thermal Activation: The switch operates on a bimetallic element that bends when the coolant temperature reaches a preset threshold, automatically engaging or disengaging the radiator fan.
• High Current Capacity: Rated for up to 20 A at 12 V DC, it can handle the electrical demands of most automotive cooling fans without overheating.
• Compact Design: With dimensions of approximately 30 mm × 15 mm × 10 mm, the switch fits easily into tight engine bay spaces.
• Durable Construction: Encased in a heat‑resistant plastic housing that protects internal components from oil, coolant, and high temperatures.
• Long Service Life: The bimetallic element is engineered for thousands of activation cycles, providing dependable operation over the vehicle’s lifespan.

Technical Specifications

Application Overview

The FAE 36110 is specifically engineered for use in the cooling systems of a wide range of vehicles, including:

• Mitsubishi Colt Mk III (4G13, 1.3 L & 1.5 L variants)
• Other compact passenger cars with similar radiator fan configurations
• Light commercial and utility vehicles that require reliable fan control

By monitoring coolant temperature, the switch ensures that the radiator fan activates only when necessary, reducing unnecessary energy consumption and extending component life. When the engine cools below the set threshold, the fan disengages, preventing over‑cooling and preserving fuel efficiency.

Installation Guidelines

1. Disconnect Power: Ensure the vehicle’s battery is disconnected to prevent accidental short circuits during installation.
2. Remove Existing Switch: Unscrew the current temperature switch or relay from its mounting bracket, noting the orientation of wiring connections.
3. Mount FAE 36110: Align the new switch with the existing screw holes and secure it using the supplied screws. Verify that the bimetallic element faces outward toward the coolant flow path.
4. Reconnect Wiring: Connect the input leads to the vehicle’s cooling fan control circuit, matching polarity as indicated by the manufacturer’s wiring diagram.
5. Test Operation: Reconnect the battery and start the engine. Observe the radiator fan behavior as the coolant temperature rises; the fan should engage at the predetermined threshold and disengage when cooling below that point.

Maintenance & Troubleshooting

• Visual Inspection: Periodically check for signs of wear, corrosion, or oil contamination on the housing and contacts.
• Functional Test: Use a multimeter to verify continuity across the switch terminals when the bimetallic element is in both open and closed positions.
• Replacement Criteria: If the fan fails to engage or disengage at the correct temperature, replace the switch with a new FAE 36110 unit.

Benefits of Choosing FAE 36110

• Reliability: Proven performance in demanding automotive environments.
• Energy Efficiency: Optimizes fan operation, reducing unnecessary power draw.
• Ease of Installation: Standard mounting and wiring make it a drop‑in replacement for many existing systems.
• Longevity: Designed to withstand thousands of thermal cycles without degradation.

The FAE 36110 Switch represents a blend of engineering precision and practical design, delivering dependable temperature control for radiator fans across a spectrum of vehicle models. Its robust construction, clear specifications, and straightforward installation process make it an ideal choice for automotive technicians and enthusiasts seeking reliable cooling system performance.
