I have an 85' 300D W124. I've just changed Radiator, T-stat, Water pump and Visco clutch fan. Aux Fan working in both low and high speeds (kicks in at 90 for High). My temp still goes up to 110 when in heavy traffic, before the visco fan change I would hit almost 120 - so there is an impovement. The only thing I have'nt done is flush my system and add 50/50 mix coolant. I am using ordinary tap water now.
We have no MB Citric acid solution here in the Philippines. Any substitute for that? I can get "citric acid powder" though from a chemical company but am afraid that this would not be the same one that MB has.
