Hey Guys,

Just bought a 1990 560SEL. My first Merecedes .

The guy I bought it from had it imported from Japan so the owner manual is in Japanese and I have no idea what it means!

I was going over the car trying to make sure that everything is in good working order and I noticed that there is a hose disconnected from the over flow tank. The hose looks like it feeds into the passenger wheel well. I blew into the hose to see if it was just an overflow to the ground or if it was hooked into something. There is a gurgle so I think there must be a second tank? Should this second tank be hooked up? Is it just a secondary overflow tank or does it serve some other purpose?

On a side note (possibly related?) the rear vent will not make heat. It blows good and hard but only cold air can never get heat from it, is there supposed to be a rear temp adjust somewhere? Does it by any chance use coolant from the second overflow and maybe a second heater core to produce heat in the rear?

One last question what the heck are the dash lights? I got most of them figured but there is one that is a circle with dashed lines around it and one that looks like a light bulb with an ! in the middle that I don't know what they are.

Any and all help/insight/tips into this fine old girl would be greatly appreciated.

Cheers =D
