Water Temp Temperature Sensor for Polaris RZR 800 2008-2014

Water Temp/Temperature Sensor for Polaris RZR 800

This water temperature sensor monitors coolant temperature on 2008-2014 Polaris RZR 800 side-by-sides so the engine management system can keep fuel delivery and cooling fan operation in check.

Overview

This water temp sensor is a direct-fit replacement for the coolant temperature sensor on 2008-2014 Polaris RZR 800 machines. It reads coolant temperature and sends that signal to the ECU, which uses the data to adjust fueling and trigger the cooling fan. It suits owners doing routine maintenance or chasing an overheating or cold-start fault.

Built For Performance

• Threaded body matches the factory coolant port for straightforward installation
• Sealed electrical connector resists moisture and vibration common in off-road use
• Thermistor element provides accurate resistance change across the operating range
• Housing built to withstand constant exposure to hot coolant and engine bay heat
• Direct replacement for the original sensor, no adapter required

Fits These Machines

• for Polaris RZR 800 (2008-2014)

On-The-Job Use

• Trail riding where consistent engine temperature keeps performance predictable
• Dune and desert runs where heat soak stresses the cooling system
• Cold-weather starts where accurate temperature readings aid fuel delivery
• Routine cooling system service and troubleshooting

Specs At A Glance

Good To Know

Q: How do I know if my temperature sensor has failed? A: Common signs include an inaccurate or inactive temperature gauge, cooling fan that never engages, hard cold starts, or a check engine light. Replacing the sensor restores correct temperature reporting to the ECU.

Q: Does this sensor need any special tools to install? A: It threads into the coolant port and connects with a standard electrical plug, so basic hand tools are usually enough. Drain or clamp the coolant line first to limit spillage.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
