Cooling Fan Switch for 1985 Mercedes-Benz 380SL & More - Standard Ignition TS-507

Help keep your cooling fan responding to engine temperature with the Standard Ignition switch TS-507. This coolant fan switch senses coolant temperature and sends the electrical signal that tells the fan controller when to bring the fan on. It is a direct-fit replacement for many vehicles, among them the 1981 Mercedes-Benz 380SL and 1989 Mercedes-Benz 560SL. See the "Vehicles it fits" section for the full list of applications and engine details.

• OE ignition expertise: Standard Ignition is a global maker of original equipment ignition products and keeps complete quality control over manufacturing, from componentry through the finished product.
• Calibrated set point: Its thermal switches are factory-calibrated to make electrical contact at the specified lower-temperature set point. Every unit is calibrated and tested to confirm the switch actuates at its specified temperature.
• Temperature-sensing element: Standard Ignition's thermal switches use one of two designs. Some use custom-formed wax pellets that expand when heated and trigger a snap-action electrical contact. Others use a formed bimetallic contact arm that moves as two fused metals expand at different rates, a creep-action design built for precise performance.
• Built for the shop: A robust design and high-grade materials are intended to meet the demanding needs of today's service professionals.

Signs this switch may need replacing include:

• a cooling fan that does not come on as the engine warms
• a fan that runs when it shouldn't
• temperature that rises at idle or in slow traffic

Wiring, relays, the fan motor or the fan controller can cause the same symptoms, so diagnose the cause before replacing. If the original switch has failed, the TS-507 replaces it.
