I need the fan settings for a 2005 C6 with a 160 degree thermostat in it. Appreciate it.

Here you go:

25% @ 192 degrees
50% @ 196 degrees
75% @ 199 degrees
100% @ 203 degrees

These should be what you need.

:iagree: Close enough.You can do 99% up top as well if you want ,not that it matters that much.:banned:

Perfect help!

Thank you

H...1957 are you saying rather thank 100% have it set at 99%? Am I understanding you?

The maximum fan setting on 07 and 08 vettes is 90%. I would go with no more than that at 203* and up.

I have a 2005, does that make a difference?

I have a 2005, does that make a difference?What is the max. in your stock tune? I would go with that as max at 203*.

You can check an 05 in the repository too. http://www.hptuners.com/customers/tune.php

I think my 05 fans, z51, were set at 90% (or 99%) up top.I don't remember!!Highway temps were in the 180's range since no fans are needed.

How are you adjusting this? With one of those diablo preditors or lap top with tuning software?
