Tim Posted June 24, 2018 Share Posted June 24, 2018 How's every one? 2007 version of the LS2 - what should the coolant temps run? recently it's been tough to keep it under 200 degrees. Flushed the system and still running too hot. Water pump is just two years old - no leaks. I run a 196 Thermostat, thinking I should run a 160. Can the fan be adjusted to run faster while driving and then run a bit longer after the car is off? Thanks Link to comment Share on other sites More sharing options...
Drewstein Posted June 24, 2018 Share Posted June 24, 2018 I believe 200-210* is fine so don't panic about sub 200* temps. The car can run much hotter before anything bad happens, not that I would push it. Plenty of guys are running in the 220s because of air flow etc. for comparison.

Chameleon Posted June 24, 2018 Share Posted June 24, 2018 OMG, Tim posted! My LS3 runs about 195, unless I'm sitting in traffic with the A/C on, then gets up around 205/210. Don't know how that compares to your LS2. From experience with prior cars, I do recommend the cooler thermostat, and there is something with the computer that can be done to improve cooling. I had a LS1 years ago that was running hot and NicD did some tweaking with it and the heating problems vanished. 1 Link to comment Share on other sites More sharing options...
Z51FITR Posted June 24, 2018 Share Posted June 24, 2018 I have the same issue on 110 degree plus days driving in town. I drive around it by keeping the revs below 2500 rpm with 2 - 4 - 6 shifts. I believe the fan speed and duration are programmable via the tune though and might be worth a try. Andy Link to comment Share on other sites More sharing options...
SixAddict Posted June 24, 2018 Share Posted June 24, 2018 Running 220 at times when using the paddle shifters and AC on, doesn't stay there long but that's about the hottest I see it go this is an LS3. Gonna look at the fan option with my Tech2 see if they can be adjusted, seems they run about 10 minutes after car is parked in the garage. Seems to run cooler when not using the paddle shifters but that's no fun..... Link to comment Share on other sites More sharing options...
TheCMSH Posted June 24, 2018 Share Posted June 24, 2018 Your radiator cooling fans won’t even kick on until 226 under non ac run conditions Wash out the fins on the radiator and the ac condenser real good, that will help you about all you need. You seem to be running temps that are within design parameters Link to comment Share on other sites More sharing options...
joe@cpr.com Posted June 24, 2018 Share Posted June 24, 2018 220 is normal operating Temps. You're under that so don't worry about it. This isn't old school stuff. Link to comment Share on other sites More sharing options...

Newer engines run hotter to allow for less emissions. Or so I hear Link to comment Share on other sites More sharing options...

Tim Posted June 25, 2018 Author Share Posted June 25, 2018 Thanks for all the replies. Yup I'm still around. Now a History teacher. My Vette is now over 105k miles. Only problems with it has been blower motor - 3 times now. Just put a new stage 2 clutch in it. Thanks again. Tim Link to comment Share on other sites More sharing options...

So when that #REDforED thing was going on, were you ever asked if the "ED" was for Erectile Dysfunction? BTW, a 160 stat, turning the fan on sooner (I start 20% at 192 and stage to 90% at 203), running 70% water to 30% coolant, and an annual cleaning of the radiator and evaporator with a water wand, will keep you cooler. The key is airflow at idle or low speeds. Link to comment Share on other sites More sharing options...
Tim Posted June 26, 2018 Author Share Posted June 26, 2018 No, but if it's something you need to talk about ...we are all here for you!!!!👀 Thanks for the additional information. I did pull off all the intake plastic and give the radiator and A/C a good hosing down last night ..I'll take her out for a bit today. Tim Link to comment Share on other sites More sharing options...
