Standard Ignition TS-229 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender for OE-Style Cooling Control

Standard Ignition TS-229 is an engine coolant temperature sender built for accurate electrical signaling in cooling-system applications. It uses a calibrated thermal design with a formed bimetal contact arm and factory-set actuation points to help maintain consistent fan-controller input on the vehicles listed below.

Compatible with 1988-1990 Oldsmobile 98 and 1989-1991 Oldsmobile Delta 88, this sender is a direct-fit service part for digital dash and gauge-equipped applications. The TS-229 is designed for dependable temperature-based switching in Oldsmobile 98 and Delta 88 cooling systems.

Key Features

• Engine coolant temperature sender for cooling-system signal control
• Standard Ignition TS-229 part number
• Bolt-on attachment method
• 1/8-27 thread size
• Female round plug-in connector
• 2 male blade terminals
• Factory-calibrated switch actuation point
• Thermal design with wax and bimetal contact movement

Detailed Description

Standard Ignition TS-229 is engineered with high-grade materials and a controlled thermal switching design to deliver precise electrical contact at the specified temperature. The sender uses a wax-based thermal element and a bimetallic contact arm to create repeatable switch movement, then transfers the signal to the fan controller when the coolant reaches the calibrated threshold. This makes it a practical replacement for temperature-sensing circuits in Oldsmobile 98 and Oldsmobile Delta 88 applications that rely on gauge or digital dash input.

This part cross-references Dynomax 36439 for the same application.

What It Helps Address

• Inaccurate coolant temperature signal to the gauge or dash display
• Cooling fan control issues caused by a faulty sender
• Intermittent temperature readings
• Delayed electrical contact at the switch point
• Replacement needs for aging OE-style temperature senders

Installation Notes and Tips

• Verify the connector style, terminal layout, and 1/8-27 thread size before installation.
• Confirm the vehicle uses the listed digital dash or gauge configuration.
• Inspect the connector and wiring for corrosion or looseness before installing the new sender.
• Use the vehicle service procedure for coolant-system service and electrical connection checks.

Quality Assurance

Standard Ignition maintains quality control throughout manufacturing, from component selection to finished-product testing. Each unit is calibrated and tested to confirm switch actuation at the specified temperature, supporting consistent performance in service applications.
