One problem related to coolant leaking has been reported for the 2003 Mercedes Benz ML500. The most recently reported issues are listed below.
Engine keeps getting over-heated even after a new engine fan has been replaced. However, after its replacement I took it to two mercedes dealership to re-inspect and make adjustment to their installment of the fan but it keeps getting overheated. I also had a new water coolant tank installed but it is also leaking out the coolant and showing the warning light. These events happen after I top up the coolant tank and drive around 50 miles, then the overheating starts and the tank starts becoming empty.
