Walker 214-91029 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender Overview

Walker 214-91029 is an OE replacement engine coolant temperature sender for vehicles that rely on accurate coolant temperature data for engine management and dash gauge operation. It measures coolant temperature and sends that signal to the ECU or instrument cluster, helping maintain correct warm-up control, cooling fan operation, fuel delivery timing, and emissions system readiness.

Built for direct replacement service, this Walker Full Service Kit application is engineered to match OE resistance values, thermal response, and thread type for a factory-style fit in the original sender location.

Key Features

• OE replacement engine coolant temperature sender
• 2 connector quantity with rectangle connector shape
• Spade terminal type with 4 terminal quantity
• High-temperature, corrosion-resistant construction for coolant exposure
• Direct-thread design for the original engine port
• Walker Full Service Kit line for service-focused replacement parts

Detailed Description

Walker Products Full Service Kit components are built for repair work that demands accurate fitment and dependable signal output. Part number 214-91029 is made to restore coolant temperature reporting in Ford, Lincoln, and Mercury applications where the sender threads into the engine block, thermostat housing, or intake manifold and connects to the factory wiring harness. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With 2001-2008 Ford Escape, 2005-2008 Mercury Mariner, 1996-1998 Lincoln Mark VIII, 1996-1997 Ford Crown Victoria, 1996-1997 Ford Mustang, 1996-1997 Lincoln Town Car, 1996-1997 Mercury Grand Marquis, and 1996 Ford Windstar, 2 terminals; Full Service Kit.

Common Problems This Part Can Address

• Inaccurate dash temperature readings
• False or erratic gauge movement
• Cooling fan control issues caused by incorrect temperature input
• Improper fuel and warm-up control from a faulty sender signal
• Emissions readiness concerns related to coolant temperature reporting

Installation Notes and Tips

Verify the connector style, terminal count, and thread type before installation. Inspect the sender port for coolant residue, corrosion, or damaged threads, and confirm the replacement is installed in the original location. After installation, check for leaks and confirm the gauge or scan data responds normally as the engine reaches operating temperature.

Quality Assurance

Walker coolant temperature senders are manufactured to OE specifications for resistance values, thermal response curves, and mounting thread type. The sensor body uses high-temperature, corrosion-resistant materials to withstand pressurized coolant, vibration, and repeated heat cycling.
