Temp Gauge stays cold???

Hello again,

I recently semi flushed my cooling system ie: ran water through it (no detergent) let it warm up emptied re ran water through it three times and then replaced coolant to 50-50. Since then my temp gauge stays cold for a VERY long time (15-20 min) before coming into the normal op. temp. range if at all. It does move but stays in blue. Any worries here?? What could cause that? oh 91 750il. Cool is better than hot but this cool?

Thanks
John

It's possible you have a busted thermostat. When my thermostat housing broke I had a similar issue. It's also possible that your coolant temp sensor is faulty as well.

How cold is it outside? This could be a factor.

Also, I think your car uses an electronically-controlled thermostat. If a sensor or other electrical connection is performing under par, it may affect the cooling system's control loop.

Temp is in the 40's lately. Seems strange that a therm or sensor would go out right after a flush but who can predict right? well will be checking both.

Thanks
