coolant questions
2004 S500 4Matic-
My car is running close to 100'C temperature. The engine fan turns on too. I will be flushing the coolant my self and will purchase the coolant from the dealership. I just need to know where the thermostat location is and how much can I expect to pay for 12.1L of coolant and a new thermostat? Also any tips while performing this task?
Thanks mbworld

your coolant should be fine
it's your car but personally i wouldn't touch the coolant.if you check the owners manual the coolant is good for allmost ever,im guessing 150k miles.if you are having temp related problems i wouldn't expect a coolant flush to have any effect on it.keep on trouble shooting.use a temp gun to accurately measure radiator temp and compare to console indicator.

Thanks for your reply. I perfer having all the fluids changed I don't know what this car had been through with the previous owner but for sure it will give me peace of mind. The coolant in Canadian weather takes alot more 'abuse' vs other places so I think it's best if I take the time to flush it out. The owners manual also states which type of coolant is best for our S500 so I will be keeping it all to OEM specs. I also noticed the engine gets very hot it's not bearable to stand close to the hood.
What is the proper operating temperature for our cars?

If it were my car, I'd have the dealer check it out, confirm that it's running too hot and diagnose the problem. You are likely to waste money, materials and time and just wind up frustrated that it's behaving exactly the same.

My car primarily the front fenders get very hot and when you try to touch them, you cant for very long. I was worried about this as well and have monitored it for at least 6 months or a year and nothing has come of it. I was also worried about the paint but everything seems to be fine. I live in Socal so I am sure our climate is tougher on coolant then the Canadian climate.

you dont guess with MB cars.the parts are expensive and if you arent proficient at taking them apart,you have a good chance of breaking something.if you make any errors in your diy and the factory finds you negligent you lose the warranty coverage.changing coolant wont lower operating temp.I cautiously and professionally maintain my MB's.i encourage forum members to maintain there own vehicles.

i absolutely agree
From my experience of being an owner and operator or a MB Dealer i am just telling you from experience. If you can't afford to take your benz to a dealer then you shouldn't own a Mercedes to begin with. Especially these people that live for their warranties. I am just speaking from experience, cause i lose money on warranted work!!!

i have experienced that usually on a normal (HOT) day you cannot stand near the hood of the car even after she has run only for maybe 5-10 miles. she gives off a lot of heat. i have many friends that own a 220 and i have asked them occasionally wether this is normal. they have all agreed. even the stealer agreed.
so i would not worry about it at all.
thats my $0.02 :-)

Benz_addict, my car runs at close to 100deg all the time. I live in Dubai where outside temperatures hover around the 110deg F for most of the year around!

Like these cars are very difficult to maintain? From my experience, they are one of the easier cars to do basic maintenance on. If something more serious is going on, of course you should take it to someone with the right tools to identify and resolve the issue.
If dealers wouldnt try to rip us off each time we went in, maybe we would be more willing to let you guys take care of the basic stuff but at the hourly rates you charge, its just way easier to do it ourselfs.
Its not about the money and more about the feeling of being taken. Nothing worse then that.

What kind of answer is it????

YES, THE PROBLEM IS IDENTIFIED AS A WRONG (GREEN) ANTIFREEZE. All Mercedeses love BLUE coolant, OEM and specifically designed by the Mercedes.
You will need to bleed your old antifreeze, filled with distilled water and run engine for 10 min with open thermostat, before you filled with blue antifreeze.
Changing antifreeze for blue will lover your Mercedes temperature by 10 degrees.
When both fenders getting hot, that simply may indicates air in the system, which need to be addressed upon changing cooling antifreeze .
