People are putting pajero viscous fan hubs on TDs now with a pajero fan, apparently it is way better than any Nissan setup. People are saying that it helps massively with keeping temps under control but I haven't actually seen one yet.Quote:

Mark, I am guessing you have checked the thermostat? - or changed it? I guess its the standard question, if it hasn't been like this - 'Whats changed?' More weight - new rear bar?
Yeah I've seen a few of them around. Some use the Colorado fan setups too with good results. Mine was good, then all of a sudden it wasn't so good. So I want to find out why. Hopefully what I have done over the last week has worked.Quote:

Now, when I swap over the front components from V belt drive to serpentine, the fan supplied is a modified unit off a duramax.Quote:

I have been told on many occasions Mark that its still well within its limits. But when its run a certain way for so long, then all of a sudden its different, even still within spec, its get me thinking why. Last January's trip back from Merimbula the kettle was seeing 115c without much effort when climbing some hills.Quote:

Its ok when your coating along a flat road. Hit a hit or slight incline and you fell the need to down shift. Different turbo, or at the least a set of 4.3's would correct this. But 4.3's is what I had, and 1st gear was almost non existant. Hence me going to 4.11's. So a differnet turbo is the fix. But I wont be doing that so the 3071 stays.
Let’s honestly swap for a day drive around up here together old mate. My honest (mechanical nuffy) belief is that many blokes drive them (build seek) too cold?
I agree that cooling systems should have the least amount of fluctuation but 75C -95C in hilly country is all I’ve ever known of these 42 great donks!
EDIT: Can click over the magic 100C and up to 105C when heavy hauling or high country 40ambient slow stuff too but no stress still mate!

Interesting, before i did all teh mods to my GU it rear HOT A Lot. EGTs could be above 500 towing all day and be bouncing off 550 most of the day. 12 hours at 550 cant be good.!!!!
When i did the turbo i replaced the Radiator with an ADRAD Copper as per factory spec. Did the Thermostat to the 77 Trident one,Fitted teh JPC HiFlow Water pump, repacked the factory viscous hub, replaced teh fan with the G35 fan and it has never got hot again.
So to the haters.. Stick it. The Water Pump is a Winner. 40d day towing a camper at 115 and over taking to 130 and teh EGTs are nothing over 400 and the water temp gauge doesn’t move. Love it. I had a Kettle. Now I Don’t.
Yeah but I’m $10k richer and still chugging!
(Bullshit & Beer that is :-) )
