Ìm going to go back to this. High EGT will result in higher water temps.... I was driving my Patrol yesterday and I noticed myself subconsciously looking at the EGT's rising as I was going up a steep hill and then watching the water temps also rise. The both drop as I came off the top of the hill.
I then remembered back, driving up the coast with the camper and knowing exactly when the water temps would start to climb just going by the EGT's. For mine, it was when the EGT's passed 260c the water temps would go up, and go up by 5degs by every 30 EGT's or there abouts...

This has a lot to do with cooling system condition.
In older systems it makes total sense to see water raise with egts. The engine is working harder, and hotter so the water would be heating up..
But if your cooling system is in good nick you may notice nothing.
I've seen 650 on the egts yet water temp didn't budge off the normal 89-91 range. .

Yeah you may, but may not too. The cooling system in mine is better than stock and i see fluctuations. But its a totally different motor so its kinda null comparing mine to this.
Get the egt gauge in first i reckon and it may show us something.

So indeed, you mentioned the cooling system was worked on recently? I know for the fact that ZD30 cooling system is very difficult to purge of the air unless done correctly. However that shows up very quickly or can, you may wanna investigate that too.
I can have 500°C EGTs on uphill climb at 100 km/h and coolant temps will not go over 92°C at 40°C ambinet temps.
So for those of you getting coolant temp rise withm the rise in EGTs the cooling system is marginal at best. ZD30 radiator size is good enough for LS2 V8 conversions.....
