I?m trying to write a custom fan tune for a 3.6 v6 so bare with me.
I checked out the factory tune for my 2015 Yukon Denali 6.2l and I get that it has a thermostat that cracks opens at 194 and is fully open by 207
And that the 3.6 is 194 and 212
Targets are a little different too. But that?s not my query.
When driving down the atreet in the Yukon the ect hang at around 186 and get as high as 196 but never crack 200
I?d say they are almost always around 190... this is is 90 degree weather and driving no faster than 45 mph
Would the fan being on to support the ac system keep the ect below thermostat opening temp like that?
