Water Temp Sensor for Polaris Sportsman Touring 800 EFI

This water temperature sensor monitors coolant temperature on 2008-2009 Polaris Sportsman Touring 800 EFI models and sends that reading to the gauge or ECU so the engine runs at the right temperature.

Overview

This water temp sensor is a replacement temperature sending unit for the Polaris Sportsman Touring 800 EFI built between 2008 and 2009. The sensor reads coolant temperature and relays it to the instrument cluster or engine management system so overheating and warm-up behavior stay visible. It suits riders doing their own maintenance and shops servicing these machines.

Specs At A Glance

Good To Know

Q: How do I know if my temperature sensor has failed? A: Common signs include a gauge that never moves, reads incorrectly, or a machine that runs poorly while hot. Replacing the sender is a typical first step in diagnosis.

Q: Does this sensor need any special tools to install? A: It threads into the coolant port like the original unit, so standard hand tools and a proper seal are usually enough. Bleed the cooling system afterward to avoid air pockets.

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