As you know its also rebuilding the new head also. You've got some cool stuff going in!
Thank god for Covid is all I can say then!!
Have had to take some 'enforced' holidays due to the lockdown and this has given me time to do the project that I started buying and planning for 18 months ago, seeing pictures of the head replacement and a couple of videos never gives an accurate time frame for such a job as to the head replacement for non professional mechanics. This will be the first head I have done (with assistance from talented BIL), always left that work to others - had never intended to touch brakes either but that one has been ticked off too in the last year.
The other advantage of the long lead time is the space to think and weigh up the risks / gambles of the unknown parts of the build. Knowing that I will be lucky to drive the D2 5,000K's a year but a fair % of those will be hard hard k's putting the vehicle at the design limits, not talking extreme 4WD, but any track can be difficult especially with weather and excess traffic (like those beastly patrols running 37's).
Things such as the, auto TC, axles and diffs etc. are to me a given from the wealth of knowledge available especially here on Aulro as well as other sites dedicated to the D2, they really do get under your skin. Do regret selling my TDi and the new owner loves it probably even more than me. Had always planned to just keep it stock as possible, not so the D2.

The one that has the most risk for me is going Davies Craig electric water pump and electric fan. Removing the existing water pump and welding it watertight then installing electric pump and 16" fan. Went with the largest pump available - EWP150 - has the greatest benefit in that if and I mean IF the temp gets high, turning the engine off, the pump AND fan will keep working and removing heat soak from the engine. The controller for the unit also sets the temp and alarms if the temps get high anyway. Essentially in high risk situations such as long climbs the pump and fan can be set essentially for maximum running at low engine speeds, this I like.
Cooling has too parts, airflow AND waterflow and being able to regulate both is where I see the ability to run a electric fan against the wisdom of running one here in Aus if I was using the stock water pump with one. Keeping the existing belts due to the rather unique TD5 system of running it as an auxiliary was also helpful as not having to source a belt to fit when a water pump in a lesser vehicle is removed.
