Radiator Fan so high
Hello Guys, I am driving a s550 07. The fan speed issue started three weeks ago. It started gradually increasing. It increased one time for 5-10 minutes and then the same for the second time and so on. And now it happens every 5 minutes. I thought at first it is because it needs flush because from the previous owner the radiator is left really dirty from the antifreeze. You can see brown mold with the water. So can anyone advise me, should I go to an electrician or should I flush the radiator?
Thanks a lot.

Car needs to be read and coolant temps observed. Your fan most likely is kicking on high because your coolant is too hot. If you have gunk in your coolant you should really do a flush and take it from there.

Re: Radiator Fan so high
Thank you for your reply guys. Now I went to the mechanic and he ran checks on everything and hes telling me now that I need to replace the oil cooler because it leaks oil and it is the reason behind the loud fan. He is going to flush too because of the oil leakage. But it is going to be an expensive job. So I am just checking if he makes sense?
