American mechanic is bad they don't know how to deal with the German car .in our country they fix the car in American they replace the parts and high labor
only in America. in Eruopean country they last longer than here
You're right. The Euro car is a different animal
Yea, they know how to work on them. And they can get parts
yes sir . in Germany all Mercedes is bus or TAXI no problem at all
Because the blower fan is not bowing as fast it should. The outside air is coming through faster when you are at highway speeds.
You could have a big air pocket in the coolant ayatem. Anytime you add antifreeze you have to leave the top off the radiator until the engine gets good and warmed up. Some people call burping the radiator. That allows that ais that's caught in there to escape and that could be causing some of the heating problems.
thank you sir so where should I check sir
As was suggested in the first handful of post get a coolant pressure tester off Amazon or from Harbor Freight. It will pressurize the system and it will slowly leak down if there is a leak. I am kind of confused because it sounded like to me you only added coolant once. That's when you burp the system ( leaving the radiator cap off until it warms up ) you will see that happen when the coolant level rises and air will push some of the coolant out. Then more than likely you'll have to add more coolant because of the air that was in the system has escaped leaving the room for extra coolant. If there is indeed a leak in the system that pressure tester will cause a leak and sometimes you can hear it if it's real quiet around. But the main thing is it will show a loss of pressure and that will indeed tell you if you have a leak or not. It'll start pushing cooling out you may be able to see it dripping and that'll narrow down here search area. Just because the car is a Mercedes-Benz doesn't change the mechanical workings of the car. It just may be designed a little differently under the hood but they all work the same. Except for Mercedes the parts and labor are much harder on the bank account.
Get the pressure kit, follow the directions and look to see if it's slowly leaking down or to see if you can find the leak while the pressure is pushing the coolant out. My first would be go to harbor freight and buy a ultraviolet light and a bottle of UV Leak Finder. That way when you put the pressure in the radiator you can move the UV light around the areas most likely to leak and you should be able to spot it relatively easily. Harbor freight has those tools and they're dirt cheap. That's the cheapest, easiest way to accomplish what you're trying to do. The kit is basically a pump that pressurizes the system. If you add the UV leak finder you'll see the fresh leak if it is leaking outside of the engine. I'm assuming you have a pair of jack stands are a couple of ramps to raise the front end up. You'll need to do that so you can get under the car to try to spot the leaks there as well. Chances are under the hood there's all sorts of covers and other parts not associated with the coolant system that could be in the way and might not let you spot it from above.
