2009 Challenger SRT8 STOCK cooling fan temp settings

[SRTbernie]

I have the Vortech V3 S/C system on my Challenger. I put up with the "check engine" off and on for a few years and I'm tired of resetting.

I replaced the 180* thermostat (included in the S/C system install) with a stock thermostat. Because the cooling fan settings were modified for the 180* my cooling fans run constantly.

Would you please advise what the settings should be for a stock thermostat so I can use my Predator to modify?

Thanks!

Not sure if a supercharger is recommended to have different fan settings but if you go to "modify stock tune" you can view the stock fan settings.

Thanks for the reply. In the Vortech system, a 180* thermostat was installed. Cooling fan settings were modified in the tune to accomodate the cooler t-stat. Because this caused a persistent "check engine" light condition and a P0128 code (coolant temp) Vortech advised replacing the 180* t-stat with a stock one, which I did. With the hotter t-stat the cooling fans run constantly because of the higher operating temp. I want to adjust the fan settings back to stock and will fine tune after that if necessary. I just don't know the stock settings.

I remember my stock t-stat was 203 degrees, I just turned my fan settings down 20 degrees for each of the 3 settings. So logic would say that if they changed your fan settings you would want to raise them by approximately 20 degrees. If they did not change them then they will be somewhere around 203 or so degrees. Hook up the predator as stated earlier and modify the fan settings.

yeah, they lowered fan temps IN the tune to compensate for the 180* t-stat. That's why the fan(s) are on all the time with the stock t-stat in now.
+20 or so sounds like a good place to start, not having the mfg numbers. Thanks!
