Temperature gauge on 2017
The temperature gauge on my 2014 M7 Z51 ran consistently at 220 degrees.
The new 2017 M7 Z51 consistently runs a a couple of ticks lower on the temp gauge.
Seems like I read somewhere they improved the cooling on the 2017's. anyone shead any light on this?
Thanks
John

One of things I've noticed is that the hard gauge always reads 220 on my '14, but when I have the numerical readouts of various parameters up on the right side in one of the Tour/Performance displays, the digital water temp read-out is between 204-208 at the same time the other is reading 220.
They probably just re-calibrated the hard gauge software.

Took mine in for the same thing....
Was told by a very credible service tech that they consistently are out of sync, and don't worry about it. This was backed up by the forum.
They read from 2 sources.
The proper gauge to watch was the digital one. I just know that 220 on the dial is 200 in real life.
No worries on my part!

Thanks for the replies, but I am pretty sure I read somewhere they improved the cooling on the 17's Can't remember where.
Actually I had two 14 C7s and the hard gauge on both registered higher than the 17. I'll check the pocket gauge and see what I find.

It sounds like that is what you want to hear and while I know they did, I think it is more along the lines of improving the cooling at max temps while running hard. Maybe that trickles down to cruising speeds, maybe not.

Starting with the 2015, the corvette got the 90C stat which is 194 degrees. I would assume the two different temp gauges we have might be sensing temp on different places on the block or heads hence the different readings when comparing the two.
What ever guage reads closest to 194 degrees or slightly higher going down the road should be the accurate one.
The fully warmed up stable engine temp should never actually be under 194 on a warm day unless you have a lower temp stat.

As I recall this is posted somewhere. The 2017 Z51 and GS M7 get an additional engine oil cooler. It sits horizontal in front of the radiator. You can see it through the grill. On the A8 that additional cooler is a tranny cooler.

You really don't want your oil running much cooler than 200. That's why many cars (haven't looked at my car yet) use radiator side tanks (in the plastic end caps) as as a heat exchanger. It's good to run through there first because it can take a lot of heat off and coolant has a lot of thermal energy it can absorb and quickly get rid off when it's hot. But it can also heat it up if it's too cold.
Aside from being designed to run at that temp, when it's hot, it will boil off water that gets in there from the air/condensation, etc. If you always ran your engine oil temps at 150, you'd probably have a lot more water mixing with your oil.
Just another reason why 160 thermostats are dumb.
