Detailed Description

VEMO V20-99-1262 is an engine cooling fan switch engineered for BMW cooling system service where the fan must respond at defined coolant temperatures. The switch uses an M14 x 1.5 thread and a 3-pin connector application noted in fitment data, with thermal switching points listed at 97-92 / 90-85°C depending on the vehicle application. This makes it a direct-match service part for BMW Z3, BMW 323i, BMW 323is, BMW 328is, BMW M3, and BMW 328i models in the stated years. VEMO V20-99-1262 is also cross-referenced to Gates 21832 for the same application.

For buyers searching by vehicle and symptom, this is the type of BMW cooling fan temperature switch used when the fan cycle needs to be restored to the correct operating range.

What It Helps Address

• Cooling fan that does not switch on at the correct temperature
• Fan operation that stays on too long or cycles inconsistently
• Overheating concerns tied to a faulty thermal switch
• BMW cooling system service after sensor or switch failure
• Temperature control issues on the radiator fan circuit

Installation Notes and Tips

Verify the thread size, connector style, and thermal switch points before installation.
