2003 C240 4Matic Coolant leak by left side rear tire

Hello,

My 2003 C240 4Matic has a Coolant leak by left side rear tire which I just noticed a few days ago. My car has been in good shape, no issues all scheduled services done on time etc... My malfunction light doesn't indicate there is anything wrong.

Just wanted to see if anyone had any idea or experienced anything similar to this.

there's no coolant back there. it is more likely brake fluid.

Or, if you have auto-ride-height, it could be hydraulic fluid.

In any event, if you are not competent to get in there and diagnose it, I would get it to a shop right away, and I'd be very careful about driving it there as well.

Good luck.

The fluid is green in color (thin water base not thick) and almost positive it is Coolant fluid.

Not exactly sure where its coming out of, possible coming from exhaust pipe however not positive.

How long have you had this problem? is your coolant level going down? are you having any other problems? Even the exaust pipe is 2 feet further back. This is very odd. go under car to see where it is dripping from. Is it your car? maybe someone elses?
Perhaps as serious head gasket problem could cause enough coolant to leak into exhaust and get out the rear. but then that is a major problem!
If you cant figure it out, see your favorite independant MB garage asap

You can tell you don't have auto-ride-height because you have a W203 - that was not an available option on your car.

If the coolant is coming from the exhaust pipe, then you do have a leaking head gasket.

What is your location,... MB coolant in North America is yellow,... not green,... unless you used non-MB (or non-OEM) coolant.

Look underneath,... where is the fluid dripping from? You should see a trail,... somewhere,...

It's possible that coolant is leaking from engine bay and then travelling along the topside of the bottom panels to get to the rear wheel,... are you parked on a slope?

If head gasket leak,... you should notice blu-ish white smoke from the tailpipe when engine is on.

I would hope that the OP had already checked that, but still, it's a good point. Those large wells in the trunk are just the right size to store jugs of extra coolant.
