Help your BMW's cooling fan switch on at the right temperature with the Standard Ignition switch TS-296, an engine cooling fan switch that the manufacturer lists as a coolant fan switch. It is a direct-fit replacement for the listed applications and fits many BMW models, including the 1987-1995 BMW 325i and 1985-1993 BMW 535i. See the "Vehicles it fits" section for the full list of vehicles and engine details.
This thermal switch responds to coolant temperature. When the coolant reaches the switch's calibrated set point, it makes electrical contact and sends a signal to the fan controller so the cooling fan can switch on.
- Calibrated and tested: Every unit is calibrated and tested to confirm that it actuates at its specified temperature. Each switch is factory-set to make electrical contact at its lower-temperature set point.
- Quality control throughout: Standard Ignition is a global manufacturer of original equipment ignition products. It maintains quality control throughout the manufacturing process, from componentry to the finished product.
- 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 part may need replacing include a cooling fan that does not come on as the engine warms up, a temperature gauge that climbs at idle or in slow traffic, or a fan that runs continuously. If a failed fan switch is the cause, this unit replaces it. Diagnose the cooling system before replacing parts.
