Water temp and oil temp

SonicVQ

Just to let you know analog needles are not any better on my G37.
From data logging, the engine coolant gauge doesn't move from 70C/158F to 105C/221F. As I understand it, this is to prevent the customer from freaking and gives the impression everything is rock solid.

As for the 370z coolant dots, here is what I have from a trusted source:
1 88-133F
2 133 - 140F
3 140 - 145F
4 145 - 150F
5 150 - 155F
6 155 - 160F
7 160 - 220F
8 220 - 240F
9 240 +

This morning. I paid more attention to the dots and my gauge. The thermostat opens at 7 Dots, which is 175F. Then settles at 180F on my SpeedHut water temp gauge which is still 7 Dots.

Fellow Z Drivers.

If that eighth dot ever lights up and stays lit, I would be pulling over for a cool down. I say this because I think the setting for it is actually higher than 220 deg F to light. My experience while track driving and/or stop and go driving with OBD2 scanner running, tells me that even at 221 Deg this light does not illuminate. I would worry only because the next dot (8th) to me really means overheat condition for my Z. My car would regularly see 221 in the Texas Heat and then the Fans would crank up only to cool the car to 210 and start the heating cycle again. I have yet to ever see this next dot light up. Knock on wood that I never do.

I did install an actual water temp gauge so that I do get a more realistic view of the water temp in the engine. A worthy expenditure in my opinion. I never liked the 'dots' for a temp gauge. Nissan should know better.
