Engine Coolant Temperature Sensor Overview

Standard Ignition TX326 is a direct-fit engine coolant temperature sensor built to restore accurate temperature readings in the vehicle’s engine system. It is factory tested and made with high-quality materials for dependable operation in demanding underhood conditions.

Compatible With 2016-2019 Ford Explorer transfer case applications and 2016-2018 Ford Focus applications, this sensor supports precise temperature signal input for vehicles that rely on accurate coolant data. The TX326 is also a fitment match for Ford Explorer and Ford Focus service needs where OE-style replacement is required.

Key Features

• Direct-fit replacement for damaged OE coolant temperature sensors
• Factory tested for consistent electrical performance
• Black and gold housing with brass and plastic construction
• Female connector with oval plug/socket design
• 2 male blade terminals for secure connection
• Built to withstand extreme engine bay conditions
• Standard Ignition TX326 replacement sensor for Ford applications

Detailed Description

The Standard Ignition TX326 engine coolant temperature sensor is engineered to replace the original unit and restore temperature readings inside the vehicle’s engine management system. Its direct-fit design helps maintain OE-style fitment, while the brass and plastic construction is selected for durability in high-heat, high-vibration environments. This part number TX326 is a practical choice for Ford Explorer and Ford Focus service work where accurate coolant temperature input is important for drivability and system monitoring.

This part cross-references DY1324 and TS5635 for the same application.

What It Helps Address

• Inaccurate coolant temperature readings
• Temperature-related warning lights or fault codes
• Poor engine data feedback to the control system
• Hard starting or rough running tied to incorrect temperature input
• Replacement needs after sensor damage or connector wear

Installation Notes and Tips

Verify connector shape, terminal count, and mounting location before installation. The TX326 uses a female oval connector with two male blade terminals, so matching the electrical interface is important for proper fitment. Confirm the application as 2016-2019 Ford Explorer transfer case or 2016-2018 Ford Focus before replacing the sensor.

Quality Assurance

Standard Ignition states that each coolant temperature sensor is factory tested and manufactured under complete quality control from component selection through final assembly. That process supports consistent performance for replacement service on Ford Explorer and Ford Focus vehicles.
