Good To Know

Q: How do I know if my temperature sensor has failed? A: A faulty sensor often causes an erratic or dead temperature gauge, poor running conditions, or a check engine light. Replacing it restores accurate readings to the gauge and ECU.

Q: Is this sensor a plug-and-play replacement? A: Yes, it installs in the factory coolant port and connects to the original wiring harness without modification. Always confirm your model year and connector style before ordering.

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