Standard Ignition TS-268 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender for Jeep Gauge Applications

Standard Ignition TS-268 is an engine coolant temperature sender built for gauge-equipped Jeep applications. It uses a bolt-on attachment, a male spade-style connector, and a 1/8-27 thread size for a direct-style replacement in the correct cooling system location.

Key Features

• Engine coolant temperature sender for gauge systems
• Bolt-on attachment method with male connector
• 1 male spade connector and 1 stud terminal
• 1/8-27 thread size
• Factory-calibrated and tested for specified actuation temperature
• Thermal switch design uses wax and bimetallic contact movement for precise electrical signaling

Product Details

Standard Ignition TS-268 is engineered for vehicles that rely on a coolant temperature sender to communicate engine temperature to the gauge circuit. The sender uses calibrated thermal-switch construction with wax expansion and bimetal contact action to create a consistent electrical signal at the specified temperature point. Standard Ignition manufactures this part with controlled materials and testing throughout production to help maintain accurate switch actuation. This part cross-references 1T1160 and 53-7558 for the same application.

• Gauge needle staying low, high, or fluctuating unexpectedly
• Failed sender signal in gauge-equipped Jeep cooling systems
• Replacement need for a worn or corroded temperature sender connection
• Restoration of proper temperature feedback on AMC-engine Jeep applications

Installation Notes and Tips

Confirm the vehicle uses a gauge-style temperature sender before ordering. Match the 1/8-27 thread size and connector style to the original unit, and inspect the terminal connection for corrosion or looseness during installation. On Jeep Grand Wagoneer, Wrangler, Cherokee, CJ7, Comanche, Wagoneer, Scrambler, J10, and J20 applications, verify the engine and gauge configuration against the listed fitment notes.

Quality Assurance

Standard Ignition builds this sender with controlled component selection, factory calibration, and end-of-line testing to confirm actuation at the specified temperature. The design and manufacturing process are intended to maintain consistent electrical contact performance for gauge applications.
