Thumbs down Help!! Overheating!

I have a 98 320 ML that I just purchased and the temp is between 80-100, as I start driving, it starts going up, so far...never past 100, but I am concerned, is this supposed to happen? It just goes up and down slowly between 80-100, and I'm scared that it will eventually overheat! Please help. Also, the antifreeze level is not at the indicated mark. Should I put more antifreeze in it?

Hey, rosey, welcome to the forum.

There are lots of things that might explain this.

If you don't know when the last time was that the cooling system was flushed and inspected, start there. It could be a cooling fan, partially blocked radiator, leak, sticking thermostat, etc. But I'd suggest starting with a flush and inspection, then go from there.

As your other reply noted, the general forum is typically not the best place to find help about a specific model, that's what the specific forums are for, so scroll on down until you see the 163 forum and pick their brains.

Take care and enjoy the ride,
Greg

Temp fluctuation is normal in MB.
I woudn't worry unless it start actually reaching 100. Boiling point for pressurized coolant is above 115 C.

Yup, seems all Mercedes run hot, it's a characteristic of the brand.

does anyone know why. On my other american made car it has a digital display that show all about the motor oil pressure, temp,odo. I pressed the button to make the temp show one day while sitting in traffic and it got up to 220F and the normal gauge didn't even move when it got that hot.
