Replacement ACDelco GM 213-928 Engine Coolant Temperature Sensor (ECT) 12 Month Warranty & USA Support

Restore accurate engine temperature monitoring with the Wholesale Sensors Replacement for ACDelco GM 213-928 Engine Coolant Temperature Sensor (ECT), backed by a 12 Month Warranty and responsive USA-based product support. Designed for compatible General Motors vehicles, this replacement coolant temperature sensor provides the engine management system with critical temperature information used during everyday vehicle operation.

The Engine Coolant Temperature sensor, commonly called the ECT sensor, monitors changes in engine coolant temperature. As the engine warms from a cold start to normal operating temperature, the sensor’s electrical characteristics change. The vehicle’s engine control module interprets this information and can use coolant temperature as an input when managing engine operation.

This Wholesale Sensors component is engineered as a perfect OEM-style replacement designed to meet or exceed OEM performance specifications for compatible applications. The primary cross-reference numbers are ACDelco 213-928 and GM 15326386. General Motors’ official parts catalog confirms that GM part number 15326386 corresponds directly to ACDelco 213-928 and identifies the component as an engine cooling temperature sensor.

Additional aftermarket interchange references associated with the 213-928 application include Delphi TS10075, Standard Ignition TX1 and TX3, NTK EF0008, Holstein 2CTS0001, Motorad 1TS1209, Walker Products 2111012 and 211-91012, among others. These numbers can help when comparing applications, but customers should use 213-928 or GM 15326386 along with the exact vehicle configuration as the primary fitment references.

The 213-928 sensor has an extensive application history across General Motors vehicles. Documented applications include select Chevrolet, GMC, Buick, Cadillac, Pontiac, and Oldsmobile vehicles. Examples include Chevrolet Camaro, Corvette, Silverado, Express, Cavalier, Beretta and C-Series applications, GMC Sierra, Savana and C-Series applications, Buick Regal and Skylark, Pontiac Firebird and Grand Am, and multiple Cadillac and Oldsmobile vehicles.

The broad compatibility range means fitment can span different years and engine configurations. For example, documented applications include select 1985-1992 Chevrolet Camaro 5.0L V8, 1987-1992 Camaro 5.7L V8, 1985-1990 Chevrolet Corvette, 1985-1992 Pontiac Firebird 5.0L V8, 1987-1997 Firebird 5.7L V8, 2001-2002 Buick Regal 3.8L, and various Chevrolet and GMC truck applications.

Because of this extensive application range, customers should not purchase based on vehicle brand alone. Always verify the complete year, make, model, engine displacement, and original sensor number. General Motors used different temperature sensors across similar vehicles, model years, engines, and sensor locations.

The 213-928 design uses a 2-terminal configuration with blade terminals and an oval connector shape. GM’s official parts information confirms the two-terminal design and oval connector. The wiring harness is not part of the sensor itself, so the existing vehicle connector should also be inspected during diagnosis.

A malfunctioning ECT sensor can create several driveability and cooling-system symptoms because inaccurate temperature information can affect how the engine control system responds to operating conditions. Depending on the vehicle, possible symptoms may include hard starting, rough idle, reduced fuel economy, incorrect cooling fan operation, an inaccurate temperature indication, overheating warnings, abnormal engine behavior, or an illuminated Check Engine Light.

A faulty ECT circuit may also be associated with diagnostic trouble codes. P0117 generally indicates an Engine Coolant Temperature circuit low-input condition, while P0118 indicates a high-input condition. On compatible applications, other cooling-system codes such as P0125 or P0128 may appear when the engine does not reach the temperature expected by the control system.

However, replacing the temperature sensor should not be the automatic response to any of these codes. A diagnostic code identifies a problem detected in a circuit or system, not necessarily a defective sensor. Corroded connectors, broken or shorted wiring, poor electrical grounds, low coolant, thermostat problems, cooling fan issues, and other cooling-system faults can produce similar symptoms.

For example, diagnostic information for a P0117 condition recommends inspecting the ECT connector and wiring rather than immediately assuming the sensor itself has failed. A damaged signal wire can produce an incorrect temperature signal even with a functioning sensor.

Installation is straightforward on many compatible vehicles, but procedures and sensor locations vary considerably. Always begin with a cool engine and follow the service procedure for the exact vehicle. The cooling system can remain pressurized when hot, and opening or servicing it at operating temperature can cause serious burns.

After allowing the engine to cool, disconnect the electrical connector, remove the original sensor using the appropriate tool, and install the replacement according to the manufacturer’s torque and sealing requirements. Some coolant loss may occur when the sensor is removed. After installation, restore the coolant to the proper level, inspect for leaks, reconnect the electrical connector, and verify proper operation.

If a diagnostic trouble code was present before the repair, clear the code with an appropriate scan tool after completing the repair and confirm that it does not return. Viewing live ECT data with a scan tool can also help verify that the replacement sensor reports a plausible temperature as the engine warms.
