Nissan Patrol 2.8td GQ egt temps?

yep! Ours is garaged for trips away so it doesn't get driven aroudn town so 90% of the km's on it are off road. Been great to us.

Just one thing to keep an eye on....I had a 1998 GU 2.8 and the 'Jesus' nut holding the harmonic balancer to the crankshaft worked loose and bu$$ered the keyway and thread. Did a bodgy job to fix it and the car is still going strong but I would recommend that you check torque this nut every 50000km or so.

haven't had a close look at it as I only picked up the car today but it's been welded in.

Similar "fix" to the one I did :-)

post turbo. Just knowing those temps will be enough for me to know of a problem or change my driving.

Thanks for the numbers.

If its post turbo I would be thinking about changing down a gear if it gets to 550 deg, probably see it climb as you climb a hill or tow something.

thanks all.

good info. Thanks for that.

My EGT saved me a huge head ache awhile back, I was towing the c/t along a flat road and noticed the temp on the egt going up, pulled off the road and open the bonnet and did all the normal checks and found nothing out of the ordinary went to get back in to the MU and noticed smoke pouring from a drives side wheel bearing on the c/t, another few hundred meters and boom.

lucky! We're going on a big 5000km trip next year around WA and NT so every bit of insurance helps.

Best other thing to install is an "Enginesaver Alarm"

Monitors water level and block temperature

Next best thing to the EGT

if you blow a hose will let you know imediately.

Have one of them now to.

I also had a digital temp gauge with the sensor attache to a bolt on the head.
It stayed in the low 80's most of the time but would creep up towards 90 at times.

Highest it got was on a long hill when EGT was at 525 and temp gauge went to 98.

Incidentally I found under most driving conditions the EGT didnt go "al over the shop" at all.
It would if you let the motor lug but in an auto its less likely to do that.

A Toyota factory temp gauge wont move at all especially if you blow a hose and the water drops out

I can only relate my experiences and those comments are mainly relating to towing. No load conditions the gauge does not vary much more that 200 degrees.

Admittedly my motor is still running in from a complete rebuild.

While the EGT which is in the dump pipe will range between 250c to 600c, the engine temp, as read on an engine guardian digital readout, probe mounted on the thermostat housing as they suggest, will not move more than 3 degrees most of that time telling me that EGTs are not as important as engine temp.

As the water in the thermostat housing is coming directly from the cylinder head and therefore from around the combustion chamber, if the internal temps were rising abnormally then it would show pretty quickly in increased water temps of much more than a couple of degrees. In my case it hasn't so far.

I was talking to a performance mechanic and he said he had his EGT sitting on 900 degrees for 5 kilometres and he held it there purposefully. Not one problem according to him.

I read so much conflicting information on this particular subject, namely EGTs that it only gets more confusing the further one reads on the subject.
One so called authority says one thing and another so called authority says another thing.

The temp gauge on the other hand makes very clear sense to me and my observations support all that I have read on that subject. This is why I advocate the temp gauge as a better alternative. If I was doing it all again I would go the Enginesaver temp gauge and stick the other $200 or more in my pocket. I got one in from America via Ebay for $129 and am very impressed with it.
