Coolant Temperature Sender for 1987-1990 Mercedes-Benz 190E & More - Standard Ignition TS-530

Help your cooling fan switch on when the engine warms up with the Standard Ignition switch TS-530, a coolant temperature sender / engine cooling fan switch that makes electrical contact once coolant reaches its calibrated set point and passes that signal to the fan controller. It is a direct-fit replacement for the 1987-1990 Mercedes-Benz 190E and the 1980 Mercedes-Benz 450SL and 450SLC. See the "Vehicles it fits" section for engine details.

• Quality control from start to finish: As a global manufacturer of original equipment ignition products, Standard Ignition keeps quality control in-house, from the individual components through the finished product.
• Factory-calibrated set point: Each thermal switch is calibrated at the factory to make electrical contact at its specified lower-temperature set point.
• Tested for actuation: Every unit is tested to confirm the switch actuates at its specified temperature. The switch then sends its electrical signal to the fan controller.
• Built for the shop: A robust design and high-grade materials are intended to meet the demanding needs of today's service professionals.

This part is cataloged under two names: coolant temperature sender and engine cooling fan switch. Its job is to sense engine coolant temperature and switch the fan circuit at the rated point. Signs it may need replacing include:

• a cooling fan that doesn't come on as the engine warms
• a fan that runs all the time
• a temperature gauge that climbs at idle or in traffic

These symptoms can have other causes, so diagnose the cooling system before replacing the switch.
