Good To Know

Q: How do I know if my overheat alarm has failed? A: A sensor that never triggers a warning during extended idle or low-speed operation may have failed, so testing it against the factory specification is recommended. Q: Can I install this sensor myself? A: Yes, it uses a plug-in connection and mounts in the cooling circuit, making it a straightforward replacement for most home mechanics.

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