hello all,
just returned from Bermagui via brown mountain. full load on patrol and towing 2tn caravan. 2nd and 3rd gear up the hill. have fitted a scan gauge and engine watchdog. water temp according to scan reached 100c for brief period scan gauge set at 94c and actually reached 96c started sending alarm. have moved watchdog temp to 98c. and no more alarms. my question to the Nissan people are.
what temp would the coolant boil allowing for correct coolant and pressure and is 100c getting too hot
what would be a realistic watchdog setting
thank you, a great site for shared info bill

Watchdog setting is irrespective of vehicle type. Drive your vehicle in a normal configuration until it gets to its normal operating temperature and note the temp on the watch dog - this is obviously its normal operating temp. You then set the alarm to 10-15 degrees hotter.

In my case the normal watchdog temp is 72 degrees - I have the alarm set to 85 degrees. During normal operation the temp does not go over 80 and normally stays on 72. On a hot day when the car has been stopped for a while the alarm will sound on start but that is just the heat soak from the metal when the engine is stopped and reduces as soon as the engine is started.

Assumimg you are using the recommended 100 % coolant (no water ) and the system is correctly pressurised (raising boiling point ) I would expect boiling point would be approx 125 deg c.
The temps you currently have are within usual limits for your vehicle in my opinion.

I also have a Patrol 3lt CRD and I have towed a 3.2 tn van up some very big long hills and the highest reading on my scan-gauge has been 94c but (and thats a big but) I also have an EGT gauge fitted and drive it so as to keep the EGT below 500c but sometimes runs to 550c max for short time. I would hate to think what your EGT got to to raise the water temp to 100C

I wouldn't worry. I had the same vehicle tow a 3tonne van around OZ for 18 months. It was fully loaded. Had a scangauge that showed similar water temps to yourself. She never missed a beat till it was rear ended by a semi at 160000kms. Sleep easy.

I have a Challenger ( diesel ) and its normal temp is approx 94 deg..

Towing a small van uphill it'll go straight to 100 deg.....a big long steep hill....115 deg..

100 deg may be a bit high for your particular vehicle, but it's not TOO high..

Did your normal temp gauge move at all ?? if not then I wouldn't worry at all..
