What I believe you have done has left mostly water in it.
Is there a dealer nearby that you can obtain the MB coolant? I'd get 2 gallons of it.
It is difficult to accesss the block drain without the car being on a hoist.
I'd drain it, put in 1 qt of straight MB coolant (undiluted) then use 50:50 MB coolant/water mix, because there is likely a rather weak mix in there right now, the 1 qt will make up for the existing weak mix that won't drain out.
GillY I really apprecite your time and effort in responding quickly.
1. So, you are saying what I did (not a right method thru hose in Resarvoir and T-stat housing open, running full heat and car running) did flushed out the system entirely?
If thats the case mentioned above (1) than I had 5 Quarts of water in the radiator and the engine. Than I added straight MB coolant into the RESERVOIR and 1 Quart of water in RESARVOIR.
If thats the case why do I need to add 4 more quarts Coolant... Right know if above is true I have 4 quarts Coolant (I know this for fact, since I poured the 1 gallon in the Resarvoir) This makes 40% Coolant and 60% Water...
What do you think... I hope I am not confusing here...
