Standard Ignition TX71 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Dodge and Jeep

Standard Ignition TX71 is an engine coolant temperature sensor built for accurate temperature reporting in the cooling system. It uses a screw-on attachment, a brass sensing body, and a 2-blade terminal layout to support reliable electrical connection on a wide range of Dodge, Chrysler, Plymouth, and Jeep applications.

Compatible With 1991-2003 Dodge Ram 1500, Ram 2500, Ram 3500, Dakota, Durango, Caravan, Grand Caravan, and related Chrysler and Jeep models, TX71 is a direct-fit coolant temperature sensor for service work on engine temperature monitoring circuits.

Key Features

• Standard Ignition TX71 engine coolant temperature sensor
• Screw-on attachment method for threaded sensor locations
• Brass sensor body with black and gold finish
• 1 female rectangular connector with plug/socket type
• 2 male blade terminals for electrical connection
• Factory-tested for electrical and temperature response accuracy
• Built to support broad coverage across many Dodge, Chrysler, Plymouth, and Jeep vehicles

Detailed Description

The TX71 coolant temperature sensor is designed to report engine coolant temperature to the vehicle’s control system so the engine can manage fueling, idle strategy, and temperature-related operation. Standard Ignition specifies tight thermistor response tolerances and tests each sensor at the factory to help maintain accurate readings. The brass construction and threaded screw-on design support dependable installation in the coolant passage on many Chrysler-family engines.

This part cross-references Gates 12052 and Walker Products 211-1103 for the same application. It is a practical replacement choice for Dodge Ram 1500, Ram 2500, Ram 3500, Dakota, and Jeep Grand Cherokee service repairs where the coolant temperature signal needs to be restored.

What It Helps Fix

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough idle related to temperature signal errors
• Cooling fan or fuel-control issues tied to sensor input
• Check engine lights caused by coolant temperature sensor faults
• Intermittent temperature signal loss from a worn sensor

Installation Notes and Tips

Verify the connector style, threaded mounting location, and terminal layout before installation. Inspect the harness connector for corrosion, damaged terminals, or coolant contamination, and confirm the sealing surface is clean before threading in the new sensor. Use the vehicle service procedure for torque and coolant handling, especially on Dodge Ram, Dakota, Durango, and Jeep Grand Cherokee applications.

Quality Assurance

Standard Ignition manufactures this sensor with in-process control from component selection through finished product testing. Each coolant temperature sensor is factory tested to help ensure accurate operation and dependable performance in service.
