SPAL Variable Temperature Control Sensor (140-165 Degree) for Brushless Fans - SBL-TSI-165P-PKG

The SPAL Variable Temperature Control Sensor (SBL-TSI-165P-PKG) is a purpose-built automatic fan control solution designed exclusively for use with SPAL brushless electric fans. If you're running a SPAL brushless radiator fan and need a clean, reliable way to automate fan engagement based on coolant or fluid temperature, this variable temperature sensor is the OEM-grade component SPAL engineered for exactly that job. With a control range of 140°F to 165°F, it lets your fan ramp up intelligently as engine temperatures rise — keeping your cooling system operating efficiently without any manual intervention.

Key Features & Benefits

• Designed Specifically for SPAL Brushless Fans: Unlike generic temperature switches, this sensor is engineered to integrate directly with SPAL's brushless fan systems, ensuring proper signal compatibility and reliable fan speed control.
• Variable Temperature Control (140°F–165°F Range): The sensor operates across a 140-to-165-degree Fahrenheit window, allowing your SPAL brushless fan to respond progressively to rising temperatures rather than snapping on and off at a single fixed point — reducing electrical stress and keeping temperatures stable.
• Automatic Fan Engagement: By automating fan activation based on actual fluid temperature, this sensor removes the guesswork of manual switching, helping prevent overheating during stop-and-go traffic, hard pulls, or high-load driving situations.
• Purpose-Built SPAL Quality: SPAL is a globally recognized name in high-performance electric cooling fans. Their brushless fan lineup is trusted across street performance builds, off-road racing, custom engine swaps, and OEM applications — and this sensor is part of that same ecosystem.
• Plug-and-Play Integration with SPAL Brushless Systems: When paired with compatible SPAL brushless fans, the sensor is intended to work within the existing wiring harness architecture, simplifying installation for builders and enthusiasts doing their own cooling system work.
• Supports Custom Cooling Builds: Whether you're wiring a single SPAL brushless fan for a custom radiator setup, an engine swap cooling system, or an off-road rig cooling solution, this sensor gives you a proper temperature-triggered activation point rather than relying on a manual toggle or afterthought relay.

Fitment

This sensor is not vehicle-specific — it is a universal component designed to pair with SPAL brushless electric fans as part of a complete cooling fan wiring and control system. It is not intended for use with SPAL's brushed fan models or with third-party fan brands. If you are building a custom cooling setup using a SPAL brushless radiator fan — whether for a street car, track build, off-road vehicle, engine swap project, or powersports application — this sensor is the correct temperature control component to automate fan operation within the 140°F–165°F range.

Before purchasing, confirm that your specific SPAL brushless fan model is compatible with this sensor package. If you have questions about pairing this sensor with your fan, our team at ThreePiece.us is available to help.

Frequently Asked Questions

Q: Is this sensor compatible with all SPAL fans, or only brushless models?

A: This sensor — the SBL-TSI-165P-PKG — is designed specifically for use with SPAL brushless fans. It is not intended for use with SPAL's brushed fan models. The "SBL" designation in the part number refers to the brushless product line.

Q: What does the 140–165°F temperature range mean in practical terms?

A: The sensor operates across a variable range of 140°F to 165°F, meaning fan activation is triggered and modulated within that temperature window. This allows for smoother, more progressive fan engagement compared to a simple fixed on/off switch — helping manage thermal load more consistently and reducing abrupt electrical demand spikes.

Q: Does this package include a wiring harness, or just the sensor?

A: The "PKG" suffix indicates this is sold as a package. Based on available sourced information for SPAL brushless fan sensor kits in this temperature range, a harness is included with the sensor. For definitive confirmation of what is included in your specific shipment, please contact our team at ThreePiece.us before or after ordering.

Q: Can I use this sensor for an off-road or race vehicle cooling setup?

A: Yes — SPAL brushless fans and their associated control components, including temperature sensors, are used in a wide range of applications including off-road racing and high-performance builds. The 140°F–165°F activation range is appropriate for many custom cooling system configurations. Make sure your SPAL brushless fan model is supported by this sensor before installing.
