This can happen when you least expect it! It happened to me right when I purchased a W109 300SEL and it can be really frustrating.

I have always dredded replacing a hood release cable. Finally on the last one I did, I decided to do something about those feelings.

When an engine is both overheating and losing coolant, you first want to exhaust all possibilities that the cause is something simple or inexpensive to repair. It is possible it might just be a stuck thermostat with a faulty water pump leaking coolant at the same time.
If a car has sat outside in the elements for long periods and has not been washed or waxed in months there are some things you need to do BEFORE you apply the buffer to the body and the final wax to the paint. This is where you will need some real "elbow grease."
In this video Kent covers the removal and replacement procedures for the sunroof air dam or otherwise known as the air deflector. Using a special technique and a plastic trim tool can prevent damage to the plastic clips. He also covers troubleshooting the reasons for improper operation.
When you are out looking to buy an older Mercedes in this time period you have to be careful. You have heard that these old Benz (particularly the diesels) can go forever! So why is mileage that important. Because contrary to those "myths" they do not go forever without impeccable maintenance.
