New driver of Clk55 Amg 2003----urgent help plz :(
I took it to the mechanic and it was leaking so I changed the coolant today, I took it for a ride to test it but it didn't work and the temperature got high and again I got the malfunction "coolant check level" when I drive slow it's normal and nothing happen but when I go fast and a lil hard the temperature gets high and the malfunction appears again

Plz if someone knows what to do tell me I've been driving the car for less than 1 week
could be as simple as a leaky rad hose...... or as involved as a blown headgasket... or bad water pump..... or bad elec fan........ I would find a reputable shop and get her checked out.
You do not want to overheat this motor...... al heads and high heat not good.
