Standard Ignition TS-556 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender Overview

Standard Ignition TS-556 is an engine coolant temperature sender built for accurate temperature signal reporting in the cooling system. It uses a bolt-on attachment method with a single male round connector and one male pin terminal for a direct electrical connection.

Compatible With select vehicle applications, this coolant temperature sender supports reliable temperature input for the gauge or control circuit. Standard Ignition TS-556 is a practical replacement choice when servicing cooling-system electrical components on applications such as Mercedes-Benz and Volkswagen models.

Key Features

• Engine coolant temperature sender for cooling-system temperature signal output
• Bolt-on attachment method for secure mounting
• Single round male connector with one male pin terminal
• Connector type and terminal layout support straightforward OE-style replacement
• Cross-reference part numbers include 0055450324 and WT729 for the same application

Detailed Description

Standard Ignition TS-556 is engineered as an engine coolant temperature sender for vehicles that rely on a sender-style temperature input. The bolt-on design, round connector shape, and single-pin male terminal configuration make it a focused replacement for applications that use this exact electrical and mounting style. If you are replacing a coolant temperature sender on Mercedes-Benz or Volkswagen vehicles, TS-556 provides the correct connector and attachment format for the listed application.

This part number, TS-556, is also referenced by interchange numbers used in the aftermarket and OE cross-reference network. That helps simplify identification when matching the sender to the original unit during cooling-system electrical repair.

What It Helps Address

• Inaccurate coolant temperature gauge readings
• Intermittent temperature signal loss
• Faulty sender connection at the cooling system
• Temperature-related warning light concerns tied to the sender circuit
• Replacement needs after corrosion or electrical wear at the connector

Installation Notes and Tips

Verify the connector shape, terminal style, and bolt-on mounting arrangement before installation. Match the original sender location and electrical connection exactly, since coolant temperature senders are application-specific. Confirm the vehicle uses the same sender-style circuit before replacing the part.

Quality Assurance

Standard Ignition parts are built for service replacement use in automotive electrical and cooling-system applications. TS-556 is identified by established interchange references, including 0055450324 and WT729, to support accurate part matching.
