Vehicle compatibility can vary significantly by model year, engine, trim, and production configuration. Always verify the complete vehicle information and original sensor part number before purchasing.
Accurate Coolant Temperature Monitoring
The 213-77 Engine Coolant Temperature Sensor uses a temperature-sensitive element designed to provide responsive coolant temperature readings for compatible vehicle electronics.
The sensor is manufactured from durable materials intended for demanding engine environments and repeated heating and cooling cycles.
Each replacement is inspected and tested for electrical response and temperature-sensing performance before shipment.
Helps Restore Engine Performance
A faulty GM 213-77 sensor may contribute to inaccurate coolant temperature information, hard starting, rough operation, poor fuel economy, cooling fan problems, or an illuminated check engine light.
Diagnostic trouble codes such as P0117, P0118, P0125, or P0128 can be associated with coolant-temperature-related problems. However, these codes do not automatically confirm that the temperature sensor itself has failed.
Wiring, connectors, cooling system conditions, thermostats, coolant levels, or other components can produce similar symptoms and diagnostic codes. Proper vehicle diagnosis is recommended before replacing the sensor.
Replacement and Installation
Before installation, allow the engine to cool completely and follow the appropriate service procedure for your specific vehicle.
Compare the replacement sensor’s electrical connection, threads, physical dimensions, and specifications with the original component before installation.
Because cooling systems may remain pressurized when hot, never remove a coolant temperature sensor from a hot or pressurized engine. Professional automotive service is recommended when appropriate.
12-Month Warranty and USA Support
Every GM 213-77 Engine Coolant Temperature Sensor replacement from Wholesale Sensors is quality inspected and backed by a 12-month warranty.
Customers also receive responsive USA-based product support for compatibility and product questions.
Before ordering, verify the vehicle year, make, model, engine, and original part number to ensure the correct replacement.
