Water Temp Temperature Sensor for Polaris RZR 4 800 2010-2014

Water Temp/Temperature Sensor for Polaris RZR 4 800

This water temperature sensor monitors coolant temperature on 2010-2014 Polaris RZR 4 800 four-seat side-by-sides so the ECU can manage fueling and cooling fan operation correctly.

Overview

This water temp sensor is a direct-fit replacement for the coolant temperature sensor on 2010-2014 Polaris RZR 4 800 machines. It measures coolant temperature and relays that signal to the engine control unit for fueling and fan control. It is a practical fix for owners dealing with gauge faults, fan issues, or cold-start problems.

• Cooling system service and fault diagnosis

Specs At A Glance

Good To Know

Q: What are signs the temperature sensor is bad? A: A dead or erratic temperature gauge, a cooling fan that fails to come on, poor cold starts, and check engine lights are typical indicators. Swapping the sensor restores correct temperature data to the ECU.

Q: Is installation difficult? A: The sensor threads into the coolant port and plugs into the factory harness, so standard hand tools are generally sufficient. Clamp or drain the coolant first to minimize spillage.

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