Compatible with Engine Cooling Fan Control Module Compatible with Toyota Mazda Pontiac, 12V Radiator Controller Replaces 89257-12010 8925712010 88975764 RE1019C RY1889 FCM110 902417

Product DescriptionThe engine cooling fan control module is the central electronic controller that governs your vehicle’s radiator fan operation. It monitors engine coolant temperature, vehicle speed, and A/C compressor activity, and signals the fan motor to run at low, medium, or high speeds as needed. Unlike a simple on/off relay, this PWM module ramps speed smoothly—delivering just enough airflow to keep temperatures stable while minimizing electrical load.When the original module fails, you may notice the temperature gauge climbing in stop-and-go traffic, the air conditioning blowing warm while stationary, fans running continuously after shutdown and draining the battery, or sporadic fan operation that comes and goes without warning. Prolonged failure risks a warped cylinder head, blown head gasket, or damaged radiator/condenser.This replacement module is a direct cross-reference for Toyota 89257-12010 / 8925712010, 88975764, and also replaces Standard Motor Products RY1889, Gates FCM110, UAC RE1019C, Dorman 902-417, WVE 6H1526, SKP SK902417, Intermotor 16704, and more. The pin-type terminal ensures a secure, factory-quality electrical connection.Technical Specifications:Product Type: Engine Cooling Fan Control Module / Radiator Fan ControllerQuantity: 1 PieceOperating Voltage: 12V DCConnection Type: Pin-type terminals (male)Control Method: PWM (Pulse Width Modulation)Key Signals: Engine coolant temperature sensor, vehicle speed sensor, A/C pressureHousing Material: Aluminum (for efficient heat dissipation)Dimensions: approx. 3.18" (L) x 3.57" (W) x 1.4" (H)OE Part Numbers: 89257-12010, 8925712010, 88975764Cross-References: RE1019C, RY1889, FCM110, 902417, 6H1526What‘s Included:1 x Engine Cooling Fan Control ModuleDirect plug-and-play replacement—retains original mounting screws

• 1. PRECISE VARIABLE SPEED CONTROL FOR OPTIMAL COOLING — This module acts as the brain of your radiator fan system, receiving real-time data from the engine coolant temperature sensor, vehicle speed sensor, and air conditioning system.
• 2. RESTORES COOLING SYSTEM OPERATION—NO MORE ENGINE OVERHEATING — When the original module fails, the radiator fan may not activate at all during idle or heavy load， causing engine temperature to rise dangerously. It may also run continuously at full speed, draining the battery and adding unnecessary wear. This replacement restores proper fan operation, ensuring coolant, condenser, and under-hood temperatures stay in the safe zone and preventing warped cylinder heads or blown head gaskets.
• 3. DIRECT OEM REPLACEMENT WITH MULTI-BRAND CROSS-REFERENCE — Precision-engineered to match original equipment specifications, this cooling fan controller is a direct plug-and-play replacement for a wide range of OE and aftermarket numbers.
• 4. DURABLE ALUMINUM HOUSING FOR TOUGH UNDER-HOOD CONDITIONS — With an aluminum housing that efficiently dissipates internal heat, this module is built to withstand the extreme temperatures and harsh conditions found in the engine bay. Construction materials resist thermal stress, creep, corrosion, and vibration, delivering long-term reliability even under demanding daily driving. The module is sealed to protect internal microprocessors from moisture, dust, and road contaminants.
• 5. SOLVES COMMON FAN FAILURE SYMPTOMS AND DTCs — A failing fan control module often announces itself with a coolant temperature gauge climbing in traffic, the A/C blowing warm at idle, fans running continuously after engine shutdown causing battery drain, or sporadic fan operation.
