Common Issues This Part May Address

• Incorrect coolant temperature signal to the engine control system
• Hard starting or rough running related to temperature input errors
• Cooling fan operation concerns tied to sensor feedback
• Temperature gauge or dash reading inconsistencies
• Check engine light conditions related to coolant temperature sensor faults

Installation Notes and Tips

Verify the connector style, thread size, and sensor location before installation, especially on applications noted as thermostat housing or oil filter housing locations. Some fitments include notes such as 18mm threads, gray color, rectangular connector, or engine-stamped identifiers, so confirm the original sensor details against the vehicle before ordering. Always inspect the cooling system condition and replace damaged connectors or corroded terminals as needed.
