Thought I'd circle back to this thread to share that the car is back, leak free and running at a constant steady temperature regardless of traffic or speed. Fan belt squeal is also gone, probably due to the new MB water pump.

We really went to town on preventative maintenance. The final list includes:

1) New MB short hose
2) New MB Water pump
3) New MB Thermostat
4) New MB Fan Belts
5) New Monark pencil glow plugs
6) New Monark injector nozzles (Rebuilt by Diesel Injector Guru Greazzer)
7) New OFV (from Diesel Injector Guru Greazzer)
8) New MB Oil Cooler Hoses (New Old Stock)
9) New fuel filters and hoses
10) Citric Acid flush then rebuilt Radiator and steam cleaned and painted oil cooler
11) Sanded down all pitting/ corrosion from aluminum housings

Interestingly and unexpectedly, the car's heating system has REALLY improved. Heats up very noticeably in <5 mins and get's really toasty in < 10 mins. And that's without the fan on!

Blue coolant is back in the system she's sealed up for another decade (hopefully!)
