Cooling Fan Relay Dual Activation 30116 by Painless Car Mount 40A 12V

Description

Product Overview

The Painless Dual Activation Cooling Fan Relay model 30116 is engineered to deliver precise temperature‑controlled fan operation for a wide range of automotive applications. Constructed with a robust copper contact material and a painted exterior for corrosion resistance, the relay supports a continuous current rating of 40 amps at 12 volts DC, delivering up to 480 watts of power. Its normally open contact type ensures that fans remain off until the thermostatic switch signals the appropriate temperature range, typically activating at 195 °F and deactivating at 185 °F. The unit features a compact car‑mount form factor, allowing straightforward installation in the engine bay or near the A/C compressor. With a coil resistance of 40 ohms and a coil voltage of 12 V, the relay provides reliable electrical performance even under demanding conditions. The inclusion of two terminals simplifies wiring, while the Posi‑tap connections for ignition and A/C lines reduce installation time and potential errors. Designed by Painless Performance Products, LLC, this relay meets automotive industry standards and carries the UPC 749823301160 for easy inventory tracking.

Usage

Designed for both street‑legal vehicles and high‑performance project cars, the dual activation cooling fan relay excels in environments where precise thermal management is critical. When the engine temperature climbs to the preset activation point of 195 °F, the built‑in thermostatic switch closes, energizing the relay coil and allowing current to flow to the cooling fans. This rapid response helps dissipate excess heat, protecting engine components and maintaining optimal operating temperatures. Conversely, when the temperature drops to 185 °F, the switch opens, cutting power to the fans and preventing unnecessary wear or noise. The relay’s 40 A rating makes it suitable for driving multiple fan units or high‑capacity A/C compressors, ensuring that even demanding cooling systems receive adequate power. Installation is straightforward: mount the unit using the provided 3/8″‑18NPT threads, connect the ignition and A/C lines via the Posi‑taps, and route the power leads to the vehicle’s electrical system. The relay’s wired configuration eliminates the need for additional adapters, and the included 1/2″ NPT to 3/8″ NPT adapter simplifies integration with existing plumbing. Whether you are upgrading a classic muscle car, retrofitting an off‑road vehicle, or enhancing a modern performance sedan, this relay offers a reliable, plug‑and‑play solution for temperature‑controlled fan operation.

FAQ

What type of vehicle is this relay compatible with?

The relay is designed for a broad range of gasoline and diesel vehicles, including classic cars, modern performance models, and off‑road trucks. Its standard 12 V DC coil voltage and 40 A current rating make it suitable for most automotive cooling fan and A/C compressor applications, provided the mounting space accommodates the car‑mount dimensions.

How do I install the thermostatic switch and set the temperature points?

The thermostatic switch is supplied pre‑calibrated to open at 185 °F and close at 195 °F. Installation involves mounting the switch in the engine head or a location that accurately reflects coolant temperature, then connecting its leads to the relay’s control circuit. If a different temperature range is required, the switch can be replaced with an aftermarket unit that matches the desired activation and deactivation points.

Can this relay be used for aftermarket A/C installations?

Yes, the relay’s 40 A capacity and 12 V coil make it an excellent choice for powering aftermarket A/C compressors. The Posi‑tap connections allow you to link the relay directly to the compressor’s power line, ensuring the system engages only when the engine reaches the specified temperature, which helps prevent premature compressor wear and improves overall cooling efficiency.

What warranty does Painless Performance Products provide?

Painless Performance Products offers a one‑year limited warranty covering defects in materials and workmanship. If the relay fails within the warranty period under normal operating conditions, the company will replace the unit at no additional cost. Technical support is available throughout the warranty term to assist with troubleshooting and installation guidance.

Is the relay compatible with modern engine control units (ECUs)?

The relay operates independently of the vehicle’s ECU, using a simple thermostatic switch to control activation. This means it can be added to vehicles with advanced engine management systems without requiring reprogramming or integration. However, for vehicles that already feature built‑in fan control logic, it is advisable to consult the vehicle’s service manual or a qualified technician to ensure the relay does not conflict with existing controls.
