Walker Products 214-1027 Engine Coolant Temperature Sender OE Replacement

The Walker Products 214-1027 is an OE replacement engine coolant temperature sender engineered to measure coolant temperature and transmit that data to the vehicle's ECU or instrument cluster. This critical input allows the engine control module to regulate fuel injection timing, manage engine warm-up sequences, trigger cooling fan activation, and verify emission system readiness.

Using a precision thermistor that changes electrical resistance in response to temperature, the sender delivers accurate real-time readings that the ECM depends on for optimal engine operation. A failed or degraded sender can cause inaccurate temperature readings, erratic dashboard gauge behavior, illuminated check engine lights, hard starting, engine flooding, or reduced fuel economy.

Key Features:

• OE replacement design engineered to meet or exceed original equipment specifications
• Matches factory resistance values, thermal response curves, and mounting thread type
• Direct-fit installation into original threaded port — no modifications required
• Installs in the engine block, thermostat housing, or intake manifold per OE location
• Built from high-temperature, corrosion-resistant materials for long service life
• Withstands prolonged exposure to pressurized coolant, vibration, and thermal cycling
• Manufactured in an ISO 9001:2008 / TS16949 certified facility
