This has probably been talked about already and I apologize for that. I have a chance to trade my 2016 z51 convertible for a 2016 2Lz Z06 convertible. I have read a lot about the Z06 but I see it looks like there is a cooling issue with the car. Is this a real problem or not that serious. Thanks for the help.

 

If you don't track it, it's a non issue

 

Even if you do track it, it's a crap shoot if it'll overheat or not. Too many variables.

 

As others have said, overheating will only be an issue on the track. If you plan to track the car, the odds are very high you'll have overheating problems. There are ways to mitigate those problems (like keeping the RPM's low) but you'll likely have problems at the track.

Other concerns with the Z06 I'd worry about, is the very real possibility of bent wheels, they are (in my opinion) too weak for real-world driving. There are lot's of threads on this issue, my only intent for mentioning it is to make you aware so you can do your own assessments. I baby mine and have had 3 bent rims. Every friend I've got (with one exception) has had bent rims on their Z06's.

Of lesser concern to me is the lower probability of a transmission issue if your prospective car is an A8 (automatic transmission). Again, reams of data on this issue too.

Hope this helps with the most often experienced problems with the car you're considering.

Good luck!

 

Thanks a lot folks. I think I will just keep my stingray. I was wondering though is this a problem with all c7 z06's or just the 2016.

 

The wheels and transmission problems are spread throughout all the C7 years. I think there may have been some minor changes in transmission fluid etc, but all the years have experienced problems.

The cooling was improved in 2018 (I think) and claims that the "newer" models are "validated" not to overheat at temperatures below 87 degrees F. I know at the test track in Spring Mountain, my 2018 Z06 would overheat by the 2nd lap if I didn't mitigate the problem and keep the RPM's low by using manual and short-shifting to keep RPM's below 4,500.

My answers are my experience and what I think is correct. Other's will surely have their views.

Here's a bit about the cooling you may find interesting.

Good luck!

For street use you will never come close to over heating the car. Since you are purchasing a Vert there is little chance you would be permitted to drive it at speed on a track. Most organizations ban Verts from track days and high performance driving schools.

Again, the A8 Z06s do not have an over heating problem on the street. For track driving over heating can be avoided by limiting the gears used not the rpms. For track duty most drivers can get by using 4th, 5th and 6th gears which is equivalent to M7 drivers using 3rd, 4th and 5th gears. M7s don't over heat and can be revved to red line multiple times per lap. It isn't the rpms it is the gear chosen.

Since you can't track a vert, you will never overheat it. what I traded in had at the time 5500 miles, what I got now has 4200 miles, in half the months, no overheating 192 degrees water or thereabouts, same as the oil after it wams up. NO A8 problems, either one (RANGE ON) Accelerated mileage in less time on the Z06 means I like it, i like it alot. And I mean ACCELERATED. a Z06 is more fun than a nekkid woman. will never go back to under 500 again.

Disagree. I think you need to find some better women

 

Bill,
I've read your posts over the years and enjoy your insight. So if you could, please help me understand your statement; "over heating can be avoided by limiting the gears used not the rpms"

Gears used and RPM's seem synonymous to me. On a track, lower gears mean higher RPMs and vice versa right? It seems your implying the overheating has something to do with the transmission (rather than RPM's at the engine) is causing the overheating issues. Am I interpreting that wrong? At Spring Mountain they told our class it was the RPM's that caused overheating and they needed to be kept under 4,500 to keep the engine from overheating. Sure enough, if I went above 4,500 my car overheated (and quickly). Of course to keep it under 4,500, I kept the car in a higher gear.

Also, in the article (I provided a link in my post above), there is this comment; "Juechter shared more information about the problem. He said the issues were mostly cars equipped with the automatic transmission, so his team changed the automatic transmission calibration and upgraded the cooling system. The eight-speed automatic has closer gear ratios than the seven-speed manual, so it tended to run at higher RPM's on the track, which caused the engine to overheat".

So, I'm trying to understand why you focus the overheating issues being gear selection, vs the resulting RPM based on the gear?

Thanks!
