Greetings MBworld readers...

The source of my cooling issues is likely the original radiator that has seen Ohio cold and Atlanta heat.

Any recommendations on flush treatments for MB radiators? Its likely pretty gunked up after all these years...

Does it even have a radiator drain? Just want to use this to drain the cooling system after using a flush product

Drain is on the right side at the bottom. Should be a red plastic screw

Red screw right side (passenger-side)....I'll give it a peek when I change the oil next week.

Thanks all! I did a Peak Radiator Flush & Cleaner treatment. Made a big difference in that the temps never get above 90C...I'll repeat this in the fall to fully clean out the radiator....
