1986 300 SDL Turbo Diesel /Purge before new injector install?

I've become the proud owner of an 1986 300sdl turbo!
and have begun doing my part to advance Kent's great place here.
The motor has 151000 miles and appears in good shape(little or no smoke/pickup/etc)
I've ordered new injectors in my excitement and other stuff before realizing that Purging is a good preventative maintence.(Came from a gas home)
will purging before installing the new injectors be of benefit?
Thanks in advance!
And so begins a new romance.....

'87 SDL transmission not shifting properly

My '87 300SDL shifts very hard between 1st and 2nd. Since replacing the vacuum modulator, the rest of the gears are fine. However, a few days ago after the car sits for a few hours it does not like to shift out of 2nd. After driving at a maximum of ~45 MPH, if I come to a stop and start over it upshifts to 3rd and 4th fairly smooth. Is there an easy fix, or am I looking at rebuilding the transmission?

1985 500 SEL coolant temperatue

1985 - 500 SEL When starting the engine from cold, the coolant temperature slowly rises until it is up in the red zone, above the 120C marked on the gage. The temperature stays there for several minutes, then drops down to 80C where it will stay. The coolant level is correct and the thermostat has recently been replaced. Is the new thermostat sticking or is this normal behavior? It worries me to see the temperature gage that high.
