QLZOZB Radiator Cooling Fan Control Module — Direct-Fit, Plug-and-Play for Discovery Sport 2015–2016

QLZOZB Radiator Cooling Fan Control Module is a direct-fit replacement that controls radiator fan speed to help manage engine temperature in Discovery Sport 2015–2016, Range Rover Evoque 2012–2016, and LR2/Freelander 2 models.

This fan control module replaces LR045248 / LR100364 and restores proper fan operation when the original unit shows signs of aging or failure. Built from durable metal and engineered plastics, the module interfaces with the vehicle’s cooling system to adjust fan output as temperature demands change. It’s supplied as a plug-and-play unit that matches factory mounting points and wiring, helping you get back on the road faster without trimming or rewiring.

How does this module affect my car’s cooling performance?

The control module monitors coolant or engine temperature signals and commands the electric radiator fan to run at the appropriate speed. When temperatures rise, the module increases fan RPM to improve airflow through the radiator; when temperatures fall, it reduces fan speed to save energy and reduce noise. Proper operation helps maintain stable engine temperature under varying traffic and load conditions.

• Increases fan speed automatically when temperature thresholds are met
• Reduces unnecessary fan runtime to lower electrical load
• Improves heat extraction under heavy traffic or towing conditions

What symptoms indicate the module needs replacement?

Signs of a failing fan control module include fans that refuse to start, fans running constantly, intermittent cooling, or higher-than-normal engine temperature readings. You may also notice reduced air conditioning performance at idle, dashboard temperature warnings, or diagnostic trouble codes related to cooling fan circuits. Timely replacement prevents overheating and potential downstream damage.

• Fans not engaging when engine gets hot
• Fans running continuously or erratically
• Elevated coolant temperature or dashboard warnings

Is installation straightforward, and will it fit my vehicle?

The QLZOZB module is designed as a direct replacement for specific Land Rover models and mounts using the original hardware and connectors—no cutting, splicing, or programming required. Most DIY-savvy owners or professional technicians can complete the swap in under an hour using basic hand tools. Confirm compatibility with your vehicle’s year and model before purchase to ensure a proper match.

• Direct replacement for Discovery Sport 2015–2016 and listed models
• Uses factory-style connectors and mounting points
• Pre-inspected before dispatch for quality assurance

What materials and reliability can I expect from this spare part?

This control module combines metal components and robust automotive-grade plastics to withstand engine-bay heat, vibration, and moisture.
