Standard Ignition TX247 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for GM Applications

Standard Ignition TX247 is a direct-fit engine coolant temperature sensor built to restore accurate coolant temperature readings in the vehicle’s engine management system. It uses copper alloy conductors for strong electrical conductivity and low resistive loss, helping maintain the proper output curve for reliable communication with the computer.

Compatible with a wide range of Cadillac, Chevrolet, and GMC models, including Silverado 1500, Sierra 1500, Tahoe, Yukon, and Camaro applications, TX247 is built for service work where accurate temperature input matters. This Standard Ignition coolant temperature sensor is engineered for dependable electrical performance and consistent fitment.

Key Features

• Direct-fit replacement for damaged OE coolant temperature sensors
• Copper alloy conductors for efficient electrical transfer
• Proper output curve to reduce temperature misreading at the computer
• Round female plug-in connector with 2 male pin terminals
• Bolt-on attachment method for straightforward replacement
• Built with durable materials for demanding repair environments

Detailed Product Overview

The Standard Ignition TX247 engine coolant temperature sensor is designed to restore accurate temperature feedback in vehicles that rely on precise coolant data for engine control and gauge operation. Its direct-fit design supports clean replacement on applications such as Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac CT5, while also covering additional GM platforms including Tahoe, Yukon, Corvette, and Express van models. In applications noted as water pump, radiator, or water outlet mounted, the sensor is positioned to match the original service location.

This part cross-references Four Seasons 74012 for the same application.

What It Helps Address

• Incorrect coolant temperature readings on the dash or scan tool
