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.\u003c\/p\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cstrong\u003eWhat SPAL brushless fan models is the SPLSBL-TSI-185P-PKG compatible with?\u003c\/strong\u003e\n\u003cp\u003eThe SPLSBL-TSI-185P-PKG is designed for SPAL's Plus Series and other brushless cooling fans equipped with the TSI sensor harness input. Confirm your specific SPAL fan model's harness connector type before ordering to verify compatibility.\u003c\/p\u003e\n\n\u003cstrong\u003eWhy would I choose the 165 to 185 degree range over higher-range sensors?\u003c\/strong\u003e\n\u003cp\u003eThe SPLSBL-TSI-185P-PKG is the best choice when running a 160 degree thermostat, building a dedicated track car with aggressive cooling targets, or any setup where you want the fan to activate before coolant temperatures reach mid-range thresholds. It provides the earliest fan engagement of the three available SPAL TSI sensor ranges.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat thread size does the SPLSBL-TSI-185P-PKG use?\u003c\/strong\u003e\n\u003cp\u003eThe sensor uses a 3\/8 in. NPT thread, which is standard on most performance radiators, thermostat housings, and intake manifold coolant ports. If your installation point uses a different thread pitch, a standard NPT adapter bushing will allow this sensor to fit.\u003c\/p\u003e\n\n\u003cstrong\u003eDo I need a relay to use the SPLSBL-TSI-185P-PKG?\u003c\/strong\u003e\n\u003cp\u003eNo. SPAL's brushless fan system manages all power switching internally through the fan controller. The SPLSBL-TSI-185P-PKG simply sends a calibrated temperature signal to the controller. No relay, no additional fuse, and no external switching hardware is needed beyond the SPAL brushless fan harness.\u003c\/p\u003e\n\n\u003cstrong\u003eIs the SPLSBL-TSI-185P-PKG appropriate for a street-driven vehicle?\u003c\/strong\u003e\n\u003cp\u003eYes, provided your cooling system is set up to operate in the 165 to 185 degree range. Most factory thermostats open at 195 degrees or higher, so this sensor is best suited to builds with upgraded lower-temperature thermostats or dedicated performance cooling systems. Installing this sensor on a stock cooling system without a matching thermostat may result in constant fan operation.\u003c\/p\u003e\n\n\u003cstrong\u003eCan I use this sensor with a SPAL twin-fan setup?\u003c\/strong\u003e\n\u003cp\u003eYes, in multi-fan applications the sensor signal can be shared or split depending on the SPAL wiring harness configuration. Refer to the SPAL brushless fan wiring documentation for your specific fan models to determine whether one sensor can trigger multiple controllers simultaneously.\u003c\/p\u003e\n\n\u003cstrong\u003eHow does the SPLSBL-TSI-185P-PKG compare to the 195P and 215P packages?\u003c\/strong\u003e\n\u003cp\u003eAll three packages are functionally identical in construction, differing only in their calibrated activation ranges. The 185P-PKG (165 to 185 degree) engages earliest, the 195P-PKG (175 to 195 degree) is mid-range, and the 215P-PKG (190 to 215 degree) engages latest. Choose based on your thermostat temperature rating and preferred coolant operating window.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat is the UPC for the SPLSBL-TSI-185P-PKG?\u003c\/strong\u003e\n\u003cp\u003eThe UPC for the SPLSBL-TSI-185P-PKG is 816211022614. The SPAL manufacturer part number is SBL-TSI-185P-PKG.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eLocate a 3\/8 in.
