I have a 1991 w126 300se and the heating is very poor, it only gives out a luke warm breeze when the car is at full temperature and if I turn the speed up it is hardly noticeable. I have purchased some 2 stage coolant flush but need to locate the drain plugs on the engine.
I have done a search and some people say there are 2 and some say there is one plug. Can someone direct me to where I can find the plug on the engine block as I would like to do a full flush of the system.
any other pointers on the process to be aware of would be much appreciated and also which is the best replacement coolant brand.
