The hood doesn't have any oil in it. Where EXACTLY is the oil coming from?

Call a locksmith and hope you didn't spend all your money on that vehicle.. chances are they're going to charge you at least $50 to open it up.

The engine oil on a 2003 Mercedes S500 is changed by placing a drain pan on the vehicle, removing the oil filter, and unscrewing the drain plug. The oil is allowed to drain, a new filter installed, drain plug re installed, and oil added to the engine.

The fuel pump is just behind the rear axle and in front of the fuel tank. There are two cylinders, one is larger than the other...that is the fuel filter, the other unit is the fuel pump. If you plan on removing it, be very careful not to "ground" your tools, it could cause a spark, and ignite the fuel that will be seeping out of the loose fuel lines. I would suggest to disconnect the battery cable to avoid any problems. I would also suggest that you replace the fuel filter at the same time...it's easier to do both at the same time. As a matter of fact, a fuel filter that hasn't been replaced in a long time can contribute to a bad fuel flow.

There are 3 ways to open the trunk of the Mercedes cls 500:

1) Use the remote key, press and hold the right bottom button

2) Use button located in driver side door, near front of map pocket.

3) Under trunk lid (approximately center of license plate) there is a lever. pull it towards you with your fingers. NOTE: All doors must be unlocked.

$71.700

Yes you need a wrench to loosen the tensioner and then release the belt slowly from the bolt in the top of alternator after that you would need a long and strong screwdriver (crowbar) to release it from the pulley it self. Do not forget to draw the diagram of how the belt serpentine around the pulley.

when you pop open your hood look to your left front corner its like a barrel but has a lid on it. Its not like the new cars where its located under the car. All you have to do it take that bolt out and untwist it and theres your dirty Oil Filter

It is about $118.00 for one, plugging in the oxygen sensor isn't so bad, but the plug itself goes up into the frame of the car and seems to dissappear somewhere inside the car. Im having trouble finding this myself.

To first open the hood it's small black lever underneath the parking brake release and near the parking brake pedal to release the hood a piece of plactic sticks out of the grill about midway up... pull on that you might not see it until you have already tried pulling the hood up some Read your owner's manual.

Yes. The heater is the red areas of the climate contols.

Replace brake pads

Thank you Captain Obvious. Can we get a real answer now? I replaced my brake pads and sensor is still lit. Trying to avoid disconnecting my battery.
