About a week ago I went to visit my future parents in law that live about 30min drive away from me. When I was coming back home that night my fan went on and stayed on for a very long time (it was 20F outside) The car was not overheating so I kept driving. The fan was now on for about 5 straight minutes and I decided to pull over. I pulled over shut the car off and the fan went off. When I restarted the car the Fan came back on and about 5 minutes into the drive it shut off and stayed off for the entire 15 minutes of the drive that was left to get home. Since last week I have not started the car or drove it because of snow on the roads here in Chicago. Today I decided to start it up and let it run a bit after about 5 min of idle a msg showed up (COOLANT! VISIT WORKSHOP!) and the fan kicked back on even tho the car was not on for the entire week and didn't even get a chance to warm up. I shut the car off and went on my way to a birthday party in our other car.
In the next week or two I'm taking the car in to do a IC PUMP, Rear Tank, Heat Exchanger and also Downpipes to SPEEDRIVEN. Before I ask Speedriven to look into the problem can anyone here help me on what this could be? I have searched and read a few threads that it could be a bad wire but who knows. I rather fix the problem myself if I can.

Any ideas or maybe someone had this issue before? I will check tomorrow to see if I'm loosing any coolant but I'm 90% sure I'm not since you can smell it right away once you start loosing it.

Thanks

How is your coolant level ?

iTrader: (1)

do a pressure test on the cooling system.
the radiators are know to go bad or weep coolant from time to time

check coolant level.

have the car read.

the message on the dash would have thrown a few codes in das.

I will check my coolant level today when I get home, I guess that is the first thing I should have done. I will also do a pressure test tomorrow since I have to get the pressure guage to do it.

Thanks

Ok, no coolant in the tank. Before this happened I remember driving down the highway and hitting something under the car.Something on the road it was a pretty loud bang and I looked outside and leaned down to look under car but everything was fine. Going to Mercedes to pick up some coolant to see if it leaks under car when I fill it.

Check also engine oil for milky color. I hope not, but it doesn't hurt to lookie lookie just to be sure.

And you don't have to buy coolant from dealer. Your local napa/ pep boys/ etc. store has zerex g-05 for mercedes Benz. Cheaper and identical to the dealer coolant.
