FAQs—Mercedes Benz 200
The engine of my Mercedes Benz 200 won't crank. I tried several times, but the engine just won't fire up successfully. Aside from the battery, what could cause this problem?
If the engine fails to crank, one of the things you can blame other than a dead battery is a bad starter. The fault may also lie with a faulty solenoid starter drive. Another possibility here is a problem with the switch circuit for the ignition. What you should do is first check the car battery to see if it's fully charged. If the problem is obviously not a failing battery, chances are, the starter is already malfunctioning. The defective part should then be replaced. The replacement starter, whether it's new or remanufactured, should have the right bolt pattern and connections. Consider the other recommended specs to find a compatible replacement.
What's the leading cause of starter failure? I recently had to replace the starter of my Mercedes Benz.
Starter breakdown or failure is most commonly attributed to prolonged cranking. Prolonged cranking can make the motor overheat. The starter may fail as well if the brushes, starter drive, and bushings get damaged or wear out. When the solenoid of the starter breaks, cranking the engine will be unsuccessful since the starter won't work anymore. Aside from this defect, a sticking starter drive mechanism may also be blamed for the failure.
I was surprised to find out that front tires of my vehicle were squeaking when I applied the brakes. The brake pads and rotors were recently replaced. When I checked the brakes, it seemed like one of the rotors is running too hot. What seems to be the problem here? I don't have a single clue.
If the brake rotor seems to run too hot, then this could mean that the brake caliper or the piston itself is sticking. It's also possible that the caliper fails to slide correctly. It may come as a surprise to you since the pads and rotors were replaced not too long ago. Unfortunately, when the pads are replaced, some may forget or fail to clean the caliper pins, bushings, and glides. This can create a problem. Aside from cleaning these caliper mechanisms, new caliper grease should have been applied to ensure smooth caliper movement. If these steps were skipped, then the piston may get stuck. The rotor may get warped. You should also check if there's excess wear on the pad.
As I checked on the motor oil of my vehicle, I found out that water seems to have mixed with the lubricant. Should I be worried about it? How can water get into oil?
The motor oil may have some water in it because of a coolant leak. Another possible reason for this is water condensation in combustion gases, although this isn't common. You shouldn't allow water to mix with the motor oil since this can make it less effective as a lubricant. As such, engine damage may occur. To prevent this, you have to find the source of the leak or figure out how water is getting into the oil system. Check the seals and other possible sources of the leak and have them replaced or repaired as needed.
