Since some time I have noticed a sound from the engine bay but not really been able to locate the problem. Noticed more sound when cold...one day I also found a bolt right under the air filter!
Today, quite a bit from home I realized that the whole cooling fan where wobbling and the whole fan blade where loose. Two of four bolts where remaining. Cracks in the metal part of the fan. Sooner or later the fan will separate completely.
Better safe than sorry, I removed the entire fan....and it will take some time to get a new one, and have to drive the car back before I can get a new fan.
That brings up a question, what does the two electric blowers do? Can I trust them for a while? I wont travel much in city.
Anyone knowing how the two electrical blowers works, and what makes them operate. I guess they only detect coolant temp or do they get input from AirConditioner as well. Never heard them operate.
Thanks for input
