• Hard starting when the engine is cold
• Rough idle or inconsistent fuel delivery after warm-up
• Cooling fan operation that does not match engine temperature
• Check engine light concerns related to coolant temperature input

Installation Notes and Tips

Verify the connector style, thread engagement, and vehicle application before installation. On many vehicles, coolant temperature sensor replacement is performed after the engine has cooled and the cooling system pressure has been relieved. Clear diagnostic trouble codes after installation and confirm the reading with a scan tool or live data stream. For fitment-specific searches, this part is used on 2011-2013 Mazda 3, 2006-2009 Ford Fusion, and 2006-2015 Mazda MX-5 Miata applications, among others.
