SKP SKTS73 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

The SKP SKTS73 engine coolant temperature sensor is a direct-fit replacement for a wide range of Toyota, Lexus, Geo, Chrysler, Dodge, Mitsubishi, Hyundai, Chevrolet, and Plymouth applications. It is listed for temperature sending switch for gauge and light applications, making it a fitment-based solution for older cooling system and instrument panel service.

Key Features

• Direct-fit replacement sensor for coolant temperature monitoring applications.
• Fits gauge and light sender applications where specified in the catalog fitment.
• Broad coverage across Toyota, Lexus, Geo, Chrysler, Dodge, Mitsubishi, Hyundai, Chevrolet, and Plymouth models.
• Part number SKTS73 for easy catalog lookup and ordering.
• This part cross-references 83420-16010 and 83420-20020 for the same application.

Detailed Fitment and Application

Compatible With 1970-1993 Toyota, Lexus, Geo, Chrysler, Dodge, Mitsubishi, Hyundai, Chevrolet, and Plymouth applications listed in the fitment table, this SKP SKTS73 sensor serves as a replacement for coolant temperature sender service where the original unit is used for gauge or warning light operation. It is especially relevant for Toyota Celica, Toyota Corolla, Toyota Camry, Toyota Land Cruiser, Toyota Pickup, Toyota Supra, and Toyota 4Runner applications, along with select MR2, Cressida, and Previa models. The SKTS73 part number is also useful when matching older OE-style references during diagnosis and replacement.

What It Helps Address

• Inaccurate coolant temperature gauge readings.
• Temperature warning light faults tied to the sender circuit.
• Failed or aging coolant temperature sending units.
• Hard-to-match replacement needs for older Toyota and Mitsubishi platforms.
• Service issues caused by corroded or worn sensor contacts.

Installation Notes and Tips

Verify the original sender style before ordering, since the catalog lists both gauge and light applications. Match the connector style, thread configuration, and vehicle application against the existing part and the fitment table. Use the vehicle-specific notes to confirm whether the application is for the gauge or the warning light circuit. For best results, inspect the cooling system connector and wiring before installation.

Quality Assurance

SKP replacement parts are cataloged for direct-fit application matching, and the SKTS73 is referenced against OE-style part numbers for the same use case. Confirm fitment by year, make, model, and sender function before installation.
