LS Engine Coolant Temperature Sensor and Wiring Harness
If you're integrating an LS powerplant into a custom chassis the Coolant Temp Sensor and Harness delivers precise temperature readings to both your engine control module and dashboard gauge for reliable heat management. This harness connects directly to factory plugs without cutting or splicing so setup is complete in minutes and wiring remains tidy under the hood. With sealed terminals and materials chosen to resist heat moisture and vibration the assembly maintains accurate temperature data that supports fine tuning and protects against overheating. By feeding consistent outputs to both systems this sensor harness helps avoid false alarms and supports smooth engine operation under load.
Precision Dual Sensor Outputs for PCM and Gauge Monitoring
The coolant temperature sensor features dual outputs that transmit real time readings in parallel to both the engine control module and dashboard gauge. This coordinated signal ensures that calibration is consistent across control and display functions, eliminating timing differences that could trigger false alarms or erratic responses. By maintaining a single data source for diagnostics and performance monitoring, tuning accuracy improves and thermal cycles can be managed with confidence. Consistent feedback from both modules is essential to safeguard engine components under sustained load and varying driving conditions.
Effortless Plug and Play Installation with OEM Connections
The harness is engineered to mate directly with LS engine connectors and common gauge inputs, requiring no cutting, splicing or adapter rewiring. Each terminal sports integrated strain relief and a secure latch that prevents detachment due to vibration or heat. This approach streamlines setup to mere minutes, allowing technicians to focus on calibration rather than chasing wiring faults. Neatly routed harness leads also facilitate future inspections without disturbing other systems under the hood.
Robust Sealed Design to Withstand Engine Bay Hazards
Sealed terminals and a durable outer jacket protect the harness from moisture ingress, chemical exposure and abrasion against chassis components. The sensor housing is molded from corrosion resistant compounds that tolerate coolant additives and road salt over extended use. Vibration and heat resistance are validated through rigorous cycle testing, ensuring signal integrity does not degrade under extreme conditions. Such reliability is critical for preventing sensor failure during track sessions or long distance drives.
Enhanced Tuning Precision Through Accurate Thermal Data
Accurate coolant temperature readings are fundamental to fuel mapping and ignition timing strategies, especially when extracting maximum power or optimizing efficiency. By delivering stable thermal feedback, the sensor prevents detonation events and reduces the risk of overheating, protecting internal engine parts. Early detection of cooling system anomalies allows preemptive maintenance before serious damage occurs. In performance applications, precise temperature insight can extend engine life and maintain consistent output across changing operating environments.
