Standard Ignition TS-530 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender for Mercedes-Benz

Standard Ignition TS-530 is an engine coolant temperature sender built for precise electrical switching in cooling system applications. It is a direct-fit option for 1987-1990 Mercedes-Benz 190E models and uses a bolt-on design with a round plug-in connector for straightforward replacement.

This Standard Ignition TS-530 coolant temperature sender is engineered with calibrated thermal actuation and tested switch points to help maintain accurate fan-control signaling. It is a practical choice for Mercedes-Benz 190E owners looking for a replacement sender that matches the original connector and terminal layout.

Key Features

• Bolt-on attachment method for secure mounting
• Male round plug-in connector with 1 connector interface
• 3-pin male terminal design
• Factory-calibrated and tested for specified actuation temperature
• Thermal switch design for precise electrical contact movement
• Built with high-grade materials for service use

Detailed Description

The TS-530 uses a thermal switching design with calibrated wax and bimetallic contact movement to transfer the electrical signal at the specified temperature set point. That construction supports accurate fan-controller input and consistent operation in cooling system circuits. For 1987-1990 Mercedes-Benz 190E applications, this sender is designed to match the original-style electrical connection and mounting style. This part number, TS-530, is also referenced in cross-application listings such as SU7353 and WT696 for the same type of service need.

Common Problems It Can Address

• Inaccurate coolant temperature signal to the fan controller
• Cooling fan cycling at the wrong temperature
• Intermittent temperature sender electrical contact
• Hard-to-diagnose cooling system warning behavior
• Replacement need for a worn or failed sender on Mercedes-Benz 190E models

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. Clean the mounting surface and inspect the harness plug for corrosion or looseness before connecting the new sender. Confirm the replacement matches the vehicle’s temperature-switch specification for 1987-1990 Mercedes-Benz 190E applications. Part number TS-530 should be checked against the original unit and vehicle service information before final installation.

Quality Assurance

Standard Ignition manufactures this sender with in-process quality control from component selection through final assembly. Each unit is calibrated and tested to confirm switch actuation at the specified temperature, supporting consistent performance in cooling system service.
