"C" 200 Cooling System

[Pookis Dad]

Hi guys, many thanks for the past advice about cruise control.

I haven't been able to remove the rear tyres & replace them with the correct size yet due to other circumstances explained below.

I have just replaced the fan hub assembly and radiator.

Everything is working except that I think I need to bleed the system, but cant find any bleed valves?!

I did ensure the interior heating controls were set at full heat before topping up. I also half filled the radiator and started the engine while topping up the rest of the way to ensure the full system got filled.

It's a 2 litre petrol 97 model year.

I drove it after topping up with coolant and the guage showed normal running temp, but the heating system blew cool, then hot as I accelerated. When I stopped and let it idle the cool air blew out again. This has never happened before and seeing as how I have just changed the radiator....... You can guess the rest.

How do I bleed this system?

It is self bleeding. Just top it up and drive it fairly hard while having the heater on full and fan speed at least to position 1 until it blows hot.

Then just top it up to the max mark.

Oh, ok. Just wansn't sure what with Benz being a bit better built than the average transport.

I don't think there will be a problem with it getting a thrashing because my wifes off out in it so it'll get a good hiding this afternoon.

Thank you.
