I swapped my v6 petrol for a 4d56 in my pajero and ever since I have had overheating issues.

all parts are new. everythign has been replaced I have bled the system twice now. still gets hot. or hot to me anyways,

here is a run down of temps vs speed

below 60 - all good, hovers at 80-88
60-90 - starts getting warm 88-95
90-100 - sits at 110c but is edgy, if there is a hill you will have to back it down
anythign over 110 she climbs above 110 and I back out of it.

any thoughts on why I am having such an issue?

before changing the rad for a new replacement all temperatures were actually lower by about 15c, so I dont have a clue why its running hotter with a new 3 core copper rad.

I am going to let it cool down and then take the thermostat out and go for another run and see if that makes a difference.
