Walker Products 211-2010 Engine Coolant Temperature Sender

The Walker Products 211-2010 Engine Coolant Temperature Sender is a direct-fit OE replacement component engineered to measure engine coolant temperature and transmit real-time data to the vehicle's ECU or instrument cluster. Operating via a changing-resistance principle, the sender continuously monitors coolant temps and feeds that signal to the powertrain control module, which uses it to govern fuel injection timing, cold-start enrichment, cooling fan activation, and emissions system readiness.

Key Features:

• Meets or exceeds OEM specifications for resistance values, thermal response curves, and mounting thread type
• Built with corrosion-resistant housing and thermal elements designed to withstand pressurized coolant, vibration, and extreme temperature cycling
• Exact OE fit — threads directly into factory port with no wiring or housing modifications required
• 100% quality inspected and tested prior to packaging
• Replaces OEM part numbers: 25037345, 8993372, 8992016, 8993105, 8993106, 8993107, 479758C1

Symptoms of a Failing Coolant Temperature Sender:

• Hard start or no-start condition
• Engine flooding or rich running
• Steady check engine light (MIL)
• Poor fuel economy
• Inaccurate temperature gauge readings

Recommended service interval is every 25,000 to 35,000 miles, consisting of inspection followed by cleaning or replacement of non-functional sensors. Walker Products has been a trusted manufacturer of fuel system components and engine sensors since 1946, and holds ISO 9001 / TS16949 certification — ensuring consistent quality across every part produced.
