I am looking to buy a Mercedes GL 500, model 2009. One of checks a friend of mine does before buying a second hand car is to start the engine and then open the hood and remove the oil cap, according to him if oil bubble out then it is not a good sign. When we did that with the GL I was interested in, oil bubbled out. Is oil bubbling out any indicator of engine problems?

There is a switch on your hood latch. They get damaged sometimes when the hood opens and closes. look down on the latch and you will see the sensor with an electrical plug. There are two 10mm bolts holding the latch in. remove them and the sensor is in the latch.

IT MEANS THAT YOUR OIL LEVEL IS VERY LOW AND NEEDS TO BE FILLED. CHECK THE OIL LEVEL WITH THE DIPSTICK IF EQUIPPED. IF NOT, THEN ADD 1 OR 2 QUARTS OF OIL TO SEE IF THE OIL LIGHT GOES OFF. IT MAY TAKE SYNTHETIC OIL SO DON'T PUT CONVENTIONAL OIL IN IT IF YOU SEE A MOBIL 1 SYNTHETIC OIL RECOMMENDATION STICKER UNDER THE HOOD. IF YOU ARE UNSURE THEN BRING IT TO A QUALIFIED TECHNICIAN A.S.A.P.. HOPE THIS HELPS. GOOD LUCK.

SOURCE: Engine Coolant Temperature Light came on

whats happening is your a/c is putting an extra load on the engine. it happens with any car. that generates extra heat. it is possible that you need your coolant topped off, but chances are that your car would have overheated before if that were the case. what i would recommend is to first check to see if the coolant level is good. if it is, then get the car up to operating temperature and check to see if the cooling fans on your radiator are working. if not, it may be a bad fan, or just a fuse or relay. if that doesnt solve your problem, have the thermostat changed out for a new one. theyre pretty inexpensive. second, if you or someone you know has the know-how, remove the radiator, plug the fittings for the transmission cooler if it has any, and use a power washer to clean the radiator out. sometimes dirt can accumilate there over time and it wont let the heat dissipate properly. a coolant flush wont be bad for your car, but probably wont make your problem go away.
