The show goes on!
Got the selector rod modification done, yaaay! No more grinding on the driveshaft! Also did a thorough coolant flush and filled with corrosion-inhibiting Mercedes Benz coolant.
Trying to just drain coolant out, I noticed that very little came out from both the radiator drain and the engine block drain, so after a bit of trial and error, I realized that if I open the engine block drain valve and force water ino the over-flow reservoir, it flushes out the entire system including the heater core!
So basically, I held a hose in it until clear water came out of the block drain valve. After that, it was just a matter of filling it, running the engine until warm, then bleeding air from the system.
Everything seemed to work fine, except that I noticed that it seems to be getting warmer than before, but my commute today didn't take long enough to really test it. Will keep an eye on this...
Also, I took a read-out of the fault codes from the engine management system (I had reset the codes last week). The fault code said 1-4-4-4, which is "all ok". This is good and bad, considering I have no starting point for the hesitation at low revs...

Could it be that you are running hotter, because with all the water you used for flushing, you have a lower coolant to water ratio and so the boiling point and heat transfer is reduced?
