Coolant spilling out from overflow tube.(w208) clk55
Hey guys, for the past couple weeks now my car has been leaking coolant from the overflow tube after extended driving time. It has been 100+ here the past month though. Coolant isnt leaking from the reservoir cap..just the overflow tube. My car temp has been hitting 85c or so. What could it be? I didnt see any leaks from the radiator itself, just the overflow. I can't get it into my mech until Monday but any help would be great!
I did flush the radiator after it did it to me twice..this is driving me nuts.

The reservoir cap might have gone bad.
It will need to be pressure tested or replaced.
They are designed to hold pressure which increases the boiling point inside the cooling system.
Try to replenish with the MB spec brown colored coolant once the problem is resolved.

Cool ill definitely have it checked out monday. The coolant that is spilling outself has always been clean etc..its just coming out from the overflow tube. The cap is 14 years old now so its not surprising if it is the case.
