Car Forum / BMW Cars / June 2007'Check Coolant Level' message e36 M3
I've checked the coolant level and it's full. The temperature gauge shows good reading...and the car runs great. 99 M3 with 136K....always serviced. The car is going in tomorrow because the heating/cooling fan motor will not stay on...it will not come on when weather is hot. There was steam vapors coming out of interior vents the other day...hand up close and felt cold but no force to it...as the fan was inoperable. Sure the above is an electrical relay problem that was discussed in the forum already...but am concerned about the computer reading telling me to check coolant level...when nothing is out of sorts (fluid-wise) Could it be the water pump? Remember the temperature reading is perfect. Anybody with an answer...or advice? > I've checked the coolant level and it's full. > [quoted text clipped - 8 lines] > day...hand up close and felt cold but no force to it...as the fan was > inoperable. In hot and humid weather, very cold output from AC will condense plumes in the cabin. Only seen once in my BMW, but an X5 with heaftier AC will readily do it. > Sure the above is an electrical relay problem that was discussed in > the forum already...but am concerned about the computer reading > telling me to check coolant level...when nothing is out of sorts > (fluid-wise) Suspect faulty sensor, loose wire etc. > Could it be the water pump?

I suggest you disconnect it, then reconnect it to see if cleaning the contacts ont he connector will make it work properly. The message and the poor fan performance are not related. > I've checked the coolant level and it's full. > [quoted text clipped - 18 lines] > > Anybody with an answer...or advice? > The Coolant Level sensor is a part that requires replacement from time to > time.

I was too embarrassed to ask. Okay....driver's side? ;^) >> >> The Coolant Level sensor is a part that requires replacement from time >> >> to [quoted text clipped - 16 lines] > > Okay....driver's side? ;^) Drivers' Side? That's relative. It's on the Fill Hole Side. > I've checked the coolant level and it's full. > The temperature gauge shows good reading...and the car runs great. > 99 M3 with 136K....always serviced. > The car is going in tomorrow because the heating/cooling fan motor > will not stay on...it will not come on when weather is hot. > There was steam vapors coming out of interior vents the other > day...hand up close and felt cold but no force to it...as the fan was > inoperable. > Sure the above is an electrical relay problem that was discussed in > the forum already...but am concerned about the computer reading > telling me to check coolant level...when nothing is out of sorts > (fluid-wise) > Could it be the water pump?

Regular fault on near all BMWs and they should be ashamed of themselves.

I'm now not clear about your question. Does it refer to the electric aux fan in front of the rad? Signature*Always remember you're unique, just like everyone else.

(But yes...I had already replaced the aux fan in front of the radiator a couple of years ago) Excluservice called and said the entire unit needs to be replaced...about $359. parts and $115. labor. |
