SPAL SBL-TSI-195P-PKG Temp Sensor 175-195 DegF Plus Series

Vehicle Fitment

• Universal - compatible with SPAL Plus Series (2nd generation) brushless fans.

Fitment Notes

• Using the wrong temperature trigger range for the application inverts fan behavior - the fan runs at FULL speed when cold and slows down as temperature rises, creating a real overheating risk on longer drives. Confirm the correct sensor range (165P, 185P, 195P, or 215P) matches the intended cooling circuit's actual operating temperature before installation.
• As with SPAL's other Plus Series sensors, verify the fan is confirmed Plus Series compatible - an older Nuova-generation sensor at the same temperature range is a different, non-interchangeable part.
• Requires the SBL-TS-HARN harness (to connect the sensor to the fan side) and one SBL-YAZ-PT10 pigtail harness per fan used - sold separately unless bundled.
• When running multiple fans, only one sensor and one SBL-TS-HARN are needed total, but a separate SBL-YAZ-PT10 is still required for each individual fan. Up to 12 fans can be run off one sensor.

Known Issue / Real-World Report

• A documented user report describes this exact sensor working correctly on the first heat cycle, then failing to trigger the fan again - either from coolant temperature rise or the 12V override wire - until the engine fully cools down. The reporting user confirmed proper wiring, verified voltage at the power source, tested a second replacement sensor with no change in behavior, and confirmed sensor compatibility directly with SPAL. This appears to be a known reliability quirk with this sensor rather than a simple installation error, and is worth mentioning to customers as something to watch for after installation, along with recommending they retain documentation of their install and reach out to SPAL support if they experience the same one-cycle-only symptom.

Product Description

The SPAL SBL-TSI-195P-PKG is a 175°F to 195°F variable temperature sensor for SPAL's Plus Series brushless fans, sitting at the upper end of SPAL's sensor range lineup - a common match for a slightly warmer thermostat setup or a primary radiator circuit that runs hotter than the mid-range 165P/185P options are tuned for.

Beyond the standard install considerations shared across this sensor family - correct generation, correct temperature range, and the required SBL-TS-HARN and SBL-YAZ-PT10 harnesses sold separately - there's a specific, documented issue worth being upfront about with this sensor: at least one detailed user report describes the fan working correctly through its first heat cycle, then failing to respond to either coolant temperature or the manual 12V override afterward, requiring a full cool-down before it will trigger again. The user in that report had ruled out the common culprits (bad wiring, insufficient voltage, a defective individual sensor unit) and confirmed compatibility directly with SPAL, which suggests this may be a real quirk in how the sensor's control logic resets rather than an isolated installation mistake.

Given that, I'd recommend setting realistic expectations with customers purchasing this specific sensor, encouraging them to test the full heat-cycle behavior after installation, and keeping SPAL's support line handy if they run into the same one-cycle-only symptom - better to flag it upfront than have it surface as a surprise complaint after the sale.
