SPI Water Coolant Temperature Sensor for Polaris Snowmobile

This SPI water coolant temperature sensor replaces OEM part number 4012115 and is designed to fit for Polaris snowmobile models. The SPI water coolant temperature sensor for Polaris snowmobile monitors engine coolant temperature for accurate gauge readings. This SPI water coolant temperature sensor is a direct replacement for the original sensor on compatible Polaris snow machines.

Overview

This coolant temperature sensor is manufactured by SPI and replaces Polaris OEM number 4012115. It screws into the engine coolant passage and sends a signal to the temperature gauge or ECU. This sensor is intended for Polaris snowmobiles requiring a replacement temperature sender.

Built For Performance

• Direct replacement for Polaris OEM part 4012115
• Precise resistance curve matches original sensor specifications
• Brass or composite body resists corrosion from coolant
• Standard thread size and connector for easy installation

On-The-Job Use

• Replacing a faulty temperature sensor that causes inaccurate gauge readings
• Fixing an engine that runs too hot or too cold due to sensor failure
• Restoring proper gauge function during snowmobile maintenance

Good To Know

Q: How do I know if this sensor fits my sled? A: Check your Polaris snowmobile’s owner’s manual or parts diagram for OEM part number 4012115. This sensor is commonly used on many 2-stroke and 4-stroke Polaris models from the 2000s onward.

Q: What happens if the coolant temperature sensor fails? A: A failed sensor can cause the temperature gauge to read incorrectly, trigger a check engine light, or cause the engine to run rich or lean depending on the system. Replacing it with a quality part restores accurate monitoring.

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