DEVMO Engine Coolant Temperature Sender with Pigtail Connector — Direct-Fit ABS

DEVMO’s Engine Coolant Temperature (ECT) Sender with plug and pigtail is a direct-fit replacement sensor designed to restore accurate coolant temperature readings on compatible GM trucks, SUVs and vans.

When an ECT sensor fails, the engine control module can receive incorrect temperature data, which affects gauge readings, fan operation and fuel trim. This DEVMO unit replaces worn or faulty senders for a range of GM vehicles from the early 1990s, providing a durable ABS plastic body and a pre-wired connector pigtail to simplify installation. It fits specified model years and commonly used OEM part numbers for straightforward cross-referencing.

DEVMO designed this sender to provide stable resistance characteristics and physical robustness for everyday driving conditions. It won’t change factory calibration but helps restore correct temperature signaling when the original sensor degrades.

• Durable ABS plastic body for long service life in engine compartments.
• Stable electrical connections to minimize intermittent gauge or ECM faults.
• Packaged as a single complete sender assembly—ready to install.

What warranty and support does DEVMO include?

The product comes with a 12-month warranty covering manufacturing defects. If you encounter issues, DEVMO provides customer service via the seller channel to help troubleshoot or arrange a replacement under the warranty terms.

• Contact through the original purchase channel for support and returns.
• Included in the package: one complete ECT sender with connector and pigtail harness.

Who is this for: This DEVMO Engine Coolant Temperature Sender is intended for vehicle owners, independent mechanics and restoration specialists who need a reliable, direct-replacement sensor for early-1990s GM trucks, vans and SUVs. Choose this part if you need an OEM-form-factor sensor with a plug-and-pigtail harness, if your dashboard temperature gauge or cooling fan behavior is erratic, or when diagnostics point to a failing coolant temperature sender. Always verify compatibility with your vehicle’s year, model and factory part number before purchase.
