Yep, the DIC is nice to have to review your engine data, but it can stress you out sometimes. I keep oil temp on my display at the track and around town until I get up to 150F (my personal oil temp level before I start romping on the engine). Coolant temp will fluctuate at normal operating temp between 190F and 230+. You'll be a bit slower when the coolant is higher as the computer will pull a little timing, but it's a totally normal operating temp. Coolant warning will coming on around 260F and there is no way you'll ever hit that unless you are just going nuts at the road course or a coolant line is plugged or some other issue.

Basically, unless you get a warning message or light, everything should be fine.

 

Good to know. I was also wondering about the seemingly high coolant temps sitting in traffic on a hot day.

Quikag, which vette's have you owned and driven? Is the ZR1 worth the premium? That is, is the whole greater than the sum of the parts, or is a guy better off slapping a blower on a C6Z and pocketing the difference for parts and repairs?

 

Slap a blower on a Z51... Z06's have a known engine issue.

 

Zr1 not z06 he said... and dude wtf I can't believe that beautiful set up c6z has that valve guide issue that was supposed to be my dream car. Now I guess I mod a z51 c6? Or make a monster out of my c5z

 

I searched for a while on corvetteforum and couldn't find any definitive number to what the oil temp should be before going WOT and revving to redline. From the few threads I've read it seems most folks agree at 169F but I have no idea if they just pulled that number outta their behinds. I guess if you've been using 150 for all your Vettes over the years then that's what I'll start doing too. Waiting for the Vette's oil temp to get from 90 to 169 is by far the most painful part of driving my car every day, lol.

 

I've owned an '01 C5 Z51, '08 LS3 Z51, and now I own a '10 ZR1. I've driven pretty much every model of C4, C5, and C6. If you only care about speed do a centrifugal blower on an LS3 and crank the boost to the moon. For a total, package the ZR1 is it, but it is hard to justify the premium. That said, once you have it, there is no regrets. The LS9 has proven bombproof which is a nice feeling for driving hard at the track.

LS7 does have some valve guide issues but its pretty easily fixed if you're going aftermarket. If you keep it 100% stock, then don't worry about it with the 5k/100k mile powertrain warranty.

 

I've used 150F for 12 years and 3 Vettes and no issues. The main point is to drive them for 5+ minutes to get the fluids warm. That will really help longevity.

'Murica!!

I went to a local cars/coffee yesterday and i usually park away out of the thick of things because i really dont think my $23k 03' vette is that amazing. Out here in the burbs we see a lot of $100k cars coming out and some double or triple that. 458 italia, (which the old guy high centered on a curb and mauled his rocker panals!) lots of Porsche, Ford GT here and there. anyway i was surprised to watch from a distance the good amount of people who made it way out to my retro styled c5z to take a peak! I was like dayum should of cleaned the wheels!!

 

The LS6's have a known valve spring ( yellow springs) issue.Just replace them...otherwise the engine is almost bulletproof.
