Mercedes 1997 C180 overheating at idle

Kay’s question:

Hi , I have just bought a Mercedes 1997 C180 which has done 69k miles. I drove it for about 10 miles without any problems but when i went to get the car washed, i left the car running for about 15 minutes, i realized that the temp gauge was almost hitting the 120 degrees heat mark but once i started to drive it again the temp gauge was going down a little bit. Is that a problem or is it normal?”

Answer:

No modern day car is really made to sit and idle for fifteen minutes just sitting, especially if the AC is on. The catalytic converters will get hot, and the cooling system will be overtaxed. That said, you should have your cooling fans checked to see if they are all coming on correctly when the engine does get warmer. Because if the car runs perfect at highway speeds but runs a lot warmer when in stop and go traffice, then the cooling fans would be suspect (as you don’t need any extra wind through the radiator when you already have 60 MPH winds when driving that speed.)

Car shaking when cold (Mercedes c180 classic 1997)

Khalid’s question:

“I have a Mercedes c180 classic 1997 when i first start the car in the morning the car has a jerking problem but once it has reached the operating temperature the jerking stops. It happens again if i start the car after and hour or so. Any advice please let me know.”

Answer:

Jerking can be either in the engine or the transmission. So, you have to discover in which system the problem exists. FIRST, have it scanned to see if any trouble codes are stored in the computer. Whether the check engine light is on or not, there can often be trouble codes stored in the computer to help discover where the problem lies. Hopefully yours has some codes stored, because if not, then it’s much harder to discover where the problem lies. It could be an ignition problem, a fuel problem, or a transmission problem. From my experience in those Mercedes with such a problem, it often lies in the fuel injection system since it runs fine after it warms up. So I’d check that system out first if no trouble codes exist in the computer.
