Walker Products 214-1009 Engine Coolant Temperature Sender

The Walker Products 214-1009 Engine Coolant Temperature Sender is an OE replacement component precision-engineered to accurately monitor engine coolant temperature and relay that data to your vehicle's instrument cluster or engine control unit (ECU). Manufactured in an ISO 9001-2008/TS16949 certified facility, this sender is built to meet or exceed all original equipment manufacturer specifications and test requirements.

The coolant temperature sender uses a changing electrical resistance value to measure coolant temperature and transmit real-time readings to the dashboard gauge or warning light. This input is critical to proper engine warm-up management, cooling fan activation, fuel injection timing, and emissions system readiness. A faulty or failed sender can cause inaccurate temperature readings, erratic dash gauge behavior, improper engine control logic, hard starts, engine flooding, a steady check engine light, or reduced fuel economy.

Key Features:

• Precision-matched resistance curve for accurate, reliable temperature measurement
• Meets or exceeds OEM specifications for resistance values and thermal response
• Built from high-temperature, corrosion-resistant materials to withstand prolonged exposure to pressurized coolant, heat, and vibration
• Direct-fit OE replacement — no modifications required for installation
• Manufactured in an ISO 9001-2008/TS16949 certified facility for consistent quality
• Restores proper instrument gauge or warning light function
