Review on 🌡️ BMW Coolant Temperature Sensor for E87 E81 E46 E90 E91 E39 E60 F10 - Lower Radiator Hose Compatible by Robert Lemons

So far, so good. Two issues that we believe are related to a potentially faulty optional electric cooling fan have been fixed: 1) The optional electric cooling fan would intermittently run at its highest "high temperature" speed even when the engine was warm or on cold days. Unusually loud. 2) This condition also caused the engine management system to go into "LIMP HOME" mode, significantly reducing engine power. In addition, replacing the coolant temperature sensor on the lower radiator hose is very easy compared to most BMWs. engine sensors. Finally, the additional electrical cooling has always worked well. Much luck!
