My 95 maxima GLE has 113K on the clock.

Just finished up period maintenance including,
(1) Cleaned up Throttle Body and IACV
(2) Replaced the fuel filter
(3) Replaced the thermostat and all the water hoses
(4) Replaced radiator cap and both upper and lower radiator hoses

Many thanks for Dave B at the South Point Nissan, all OEM parts were used except for the upper and lower radiator hoses which I got a while ago from SummitRacing.

The project went well and uneventful. The car runs smoother and idle speed much lower and stable. The only thing, kind of worrisome is the water temperature seems to be a bit higher than before. I remember my ScanGauge reading for water temperature prior to the project was around 184, now I am getting 186-190 (even saw 191 when idle at the traffic light). Is that making any sense? I was expecting lower temperature, not higher.

BTW, I have run a heating/cooling self-diagnoses, all went well except for the code 25 - sunload sensor whatever that means.

 

If you didn't do your diagnosis in direct sunlight, that's why you got code 25.

Sure you bled all the air out of the system?

IMO, I wouldn't be concerned over 6 degrees; that's well within an acceptable margin. Could be easily explained simply by manufacturing tolerances with the thermostat, a slightly different regulated temperature.

 

I took a couple of rounds to bleed the air out to the level that there is not much room for refill any more. Of course, I will continue check and refill for the next week or so. I was hoping that it was the cause for the temperature rise, but it does not look like that way at this point. The only sensible explanation is what you suggested about the manufacturing tolerances unless I screwed up something else.
