Product Overview
A false temperature reading, hard cold starting, an over-rich mixture, or a cooling fan that behaves at the wrong time can lead diagnostics to the coolant-temperature circuit. Before replacing the sensor, check actual coolant temperature, coolant level, trapped air, connector condition, harness continuity, and fan control.
The sensor reports engine coolant temperature to the vehicle electronics so fueling and cooling decisions can be made correctly. Match the two reference numbers, connector key, threads, and sensor tip to the removed part because Polaris fitment can change by year and engine.
Key Features & Performance
- Reports coolant temperature to the engine-control system
- Replaces Polaris 4010644 and cross-reference 0281002209
- Helps correct an inaccurate temperature signal after circuit testing
- Designed for matching Polaris liquid-cooled applications
Replaces Part Numbers
- 4010644
- 0281002209
Common Uses
- Replacing a sensor with an open, shorted, or implausible reading
- Correcting fan operation after the relay and wiring pass testing
- Repairing poor cold-start fueling linked to the temperature signal
- Resolving a temperature-related fault code after connector inspection
Technical Specifications
- Product Type: Engine Coolant Temperature Sensor
- Signal Type: Temperature-dependent electrical signal
- Condition: New
- Replacement Type: Aftermarket
Installation & Fitment
- Let the engine cool fully and relieve cooling-system pressure
- Compare the connector key, threads, tip length, and reference number
- Inspect the plug for coolant intrusion, spread terminals, and broken wiring
- Refill and bleed the cooling system, then verify live temperature data
Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Production date, serial number, engine option, dimensions, connections, and previous repairs can change the part used within the same model. Compare the removed item and service information before purchase.
Frequently Asked Questions
Q: Can this sensor make the cooling fan run at the wrong time? A: Yes, if its signal is inaccurate. A relay, fan motor, wiring fault, low coolant, or trapped air can create similar symptoms.
Q: Is this the same as an air-temperature sensor? A: No. This listing is for the engine coolant temperature sensor used in matching Polaris applications.
Q: What is the safest way to confirm this fits? A: Use the compatible list as a starting point, then compare the original reference number, dimensions, connections, mounting details, production date, and equipment or engine serial information.
Q: Who manufactures this service part? A: This is a new aftermarket part. The brand and model names identify the applications it is intended to service.
