SPAL Variable Temperature Control Sensor (190-215 Degree) for Brushless Fans

Dial In Your Brushless Fan Switch Point with the SPLSBL-TSI-215P-PKG Temperature Sensor

The SPLSBL-TSI-215P-PKG is SPAL's variable temperature control sensor package designed specifically for use with SPAL brushless cooling fans. It provides a preset activation range of 190 to 215 degrees Fahrenheit and uses a 3/8 in. NPT threaded body for direct installation into a radiator or intake manifold port. The SPLSBL-TSI-215P-PKG eliminates the need for a separate relay or switch box by giving the brushless fan controller a clean, calibrated signal to trigger fan operation at the correct coolant temperature threshold for your engine.

About SPAL

SPAL Automotive is an Italian-engineered, globally recognized manufacturer of electric cooling fans, blower motors, and fan control systems. Founded in 1959, SPAL supplies OEM-level components to automotive manufacturers worldwide and is widely considered the benchmark for high-efficiency brushless cooling fan technology in both OEM and aftermarket applications. Their brushless fan systems are used across racing, motorsport, and performance street builds where consistent, reliable thermal management is non-negotiable.

Frequently Asked Questions

The SPLSBL-TSI-215P-PKG is designed for use with SPAL's Plus Series and other brushless cooling fans that use the matching TSI temperature sensor harness input. Always verify your specific SPAL fan model's wiring harness requirements before purchasing to confirm sensor connector compatibility.

The sensor is factory-calibrated to trigger fan activation somewhere in the 190 to 215 degree Fahrenheit range. You can adjust the threshold within that window to match your engine's ideal operating temperature and your cooling system's response time requirements.

The sensor body uses a 3/8 in. NPT thread, which is one of the most common thread standards found on aluminum radiator side tanks, intake manifold water ports, and aftermarket fittings. If your radiator or manifold has a different thread size, an NPT adapter bushing will be required.

The SPLSBL-TSI-215P-PKG is specifically engineered for use with SPAL brushless fan controller harnesses. It is not intended to replace an OEM coolant temperature sensor or ECU input sensor. It should be used only as a dedicated trigger for SPAL brushless fan activation.

No. The SPAL brushless fan system handles motor switching internally through the controller. The temperature sensor simply sends a signal to the controller to turn the fan on and off. No external relay, fuse block modification, or switching hardware is required beyond the standard SPAL brushless fan wiring harness.

The 190 to 215 degree activation range is well-suited for engines that run stock thermostats in the 195 to 205 degree range. The fan will engage before coolant reaches critical temperature, making it a reliable choice for daily-driven vehicles with SPAL brushless fan upgrades.

The SPLSBL-TSI-215P-PKG includes the wiring harness adapter needed to connect the sensor directly to a SPAL brushless fan controller harness, making installation simpler than sourcing the sensor and adapter separately. The bare SBL-TS215P is available for builds where the harness adapter is already on hand.

SPAL products are manufactured to OEM-grade quality standards. For specific warranty terms and conditions applicable to this part, contact SPAL directly or refer to the documentation included with the package at the time of purchase.

Installation Instructions

1. Identify a 3/8 in. NPT threaded port on your radiator side tank, thermostat housing, or intake manifold water passage closest to the coolant outlet.
2. Remove any existing plug or sensor from the port and clean the threads.
3. Apply thread sealant or PTFE tape to the SPLSBL-TSI-215P-PKG sensor body threads.
4. Thread the sensor into the port by hand, then torque to the sensor manufacturer's specified torque value, being careful not to overtighten in aluminum housings.
5. Connect the sensor pigtail to the corresponding input on your SPAL brushless fan controller wiring harness.
6. Reconnect the battery and start the vehicle. Monitor coolant temperature with a scan tool or gauge until it rises into the 190 to 215 degree activation range and confirm the fan engages correctly.
7. Check all connections and the sensor port for coolant leaks at operating temperature.
