EGTs 300* - Autron
Boost 8lb -Autron
sitting on 95kms

slight hill / gradual rise -
temp alarm goes off
factory gauge goes just past half way ( to about 92* off a 90* angle)
air con goes off
boost spikes to 12lb
EGT goes to 550*

radiator was replaced with new Nissan rad Xmas 2011
rad was flushed Xmas 2013
using factory coolant

is it my rad........????
is it my thermostat..........?????
is it my water pump.........?????
is it my Viscus fan...........?????
is it the fan itself.............????
is it a shit heap because the air con goes off when its a 43* day...........YES..............

I welcome your suggestions...........

went to Joondalup 4x4 yesterday for them to have a look at what could possibly be wrong
well now........

is it my rad........remember, it was flushed Xmas 2013 - they took it out and back flushed it - lots of scale I was told.........
is it my thermostat..........old thermostat marked at 85* - didnt open untill 92* and never fully opened even at 110* - temp probe in water bench test - new thermostat put in
is it my water pump.........was an after market brand, compared to new Nissan one - slightly larger fins on the impellor from Mr Nissan
is it my Viscus fan...........was not working properly - pulled apart, small valve for oil movement was "jammed / stuck" shut- replaced with new anyway
is it the fan itself.............one small-ish crack, apart from that and dirty - looked ok

while the radiator was out, they also blew the Aircon rad out (from engine side) was lots and lots of dust and dirt and leaves came out

now have to hook up the Van and go for a drive to see if it is alot better, hopefully this weekend go for a drive and find out

again, sorry for the highjack Bloodyaussie

mate I've got fingers & toes & goolies crossed, hoping thats it sorted

I actually have doubts as to my Thermostat and what temp rating it was ?

I will be taking my radiator out again very soon as the Australia Day trip I was a bit silly and got caught up in the excitement of owning a TD42 and lots of mud at Krisso's.

The water crossing I did in the dark filled it with reeds and heaps of sediment so I will look to replacing the thermostat then.

Just reading a blokes write up on fitting an oil cooler with a thermostat as he lives in the desert and he say's it has done wonders to his temp levels?

tell me more.......................

Running a cooler via a oil filter adapter plate that I think has a valve that opens depending on heat.. all the cheap ones on ebay do not have this and oil runs through them all the time.

There are heaps of kits you can buy.... this is a larger one and probably overkill. http://www.ebay.com.au/itm/AN10-Univ...item4d238dc505

He was claiming that living in the hot conditions of the top end he saw temps of 120 regularly but now it sits at 95... I have seen others mention this and I did see one car at the wreckers with this set up (no it was not a transmission cooler)...

Not sure if there are issues with oil working at correct temps or what?

thanks for that BA...

someone I was talking to recently said something about them, but I didnt quite understand what they were referring to

now you have answered the question

looks the goods though.

not too sure if it would effect the oil that greatly to worry about damage, however buy the looks of it, it would greatly help in reducing the temps on already hot oil on long distances

where to mount the thing though............

How does oil temperature affect water temp??

???????????? ????????? ???????????
