Nissan Patrol 4x4 (Africa)

Hi all. I am hoping someone can shed some light on this.
I have not used my Patrol for a couple of months and yesterday I took it out for a spin. I immediately noticed that the EGT's went up very slowly and never went passed 250 C. even when doing 120Ks an hour. They also moved down very slowly too. I dont think there is anybody here in Hibberdene to help me and am hoping I wont have to take the Patrol to Durban to sort it out. Its a 2005 3.0l and the madman was installed over a year ago.
Many thanks.

Does the performance feel correct?

Thats very low EGT's. Is it low on power?

The Patrol was striking that Zuma must go ;)

Hi Tinus and Michael. The trucks performance has not changed at all so I suspect it is directly related to the EGT. I had always watched the temperature like a hawk and never noticed anything change except for now, a drastic difference.

Bad earth or corroded connectors between madman and thermal probe wire but shouldn't be constant if faulty????

Was it always this low?

Do you measure before or after the turbo?

Hi Christo. The probe is before the turbo, I think between 2 and 3 cylinders. It always moved very rapidly up and down and I was able once to get it just below 600c going flat out up a hill. However, I cant compare apples with apples as I have never watched the temperature changes on another Patrol. Perhaps I can get feedback here as to how rapidly the temperature should change. With mine, if you traveled at a constant speed, say about 80, and then suddenly accelerated, the temp used to move up at an alarming rate until it reached the high 400 c and then would slow down and slowly creep up to the mid 500c. Would that be normal?

Yip very normal all to do with the amount of right foot and uphill infront of the car ...

Sounds like a faulty probe or something related to a wrong reading. If those temps ypu are getting were correct your Patrol would be very very slow and I dont even think it would get to 120km/h.
EGT's fluctuate quite a bit and responds to the amount of fuel you give the engine. Coasting at 120km/h you can expect to see 370 to 450 degrees or more depending and the gradiant of the road.
