Coolant/antyfreeze

[locopr31]

Hello everyone:

I have fix must of my problems on my w202. Now every other day I am runing out of antifreeze. The light goes on inside the car. But I don't see any leaks. Please someone let me know what could be. As the summer is here and I really don't want it to run hot on me.

thank you
zeke.

1. As you keep on adding fluid to the reservoir, I hope that you are not continuing to add the anti-freeze itself. Are you adding water?

2. As you have stated that you see no leaks, but that the reservoir keeps emptying, I might guess that at some point, coolant/water was added to the engine while it was off, or the system was not "burped" resulting a less than proper fill. Just a guess of course based on the information that you've given

3. Try opening up the coolant fill cap, turning the defroster on and adding water to the reservoir until it hits the bottom of the black top. Once that's full, let the engine run for a while with the coolant fill cap off, to let the system "burp", add water as the fluid level goes down, and continue to run until the reservoir level has stabilized.

For reference you can check out this thread, as the basic procedures may help you pinpoint what is going on in your situation:
