On the last run, when it was 90F+ outside, I run AC most of the time ON and noticed lower coolant temp by 5C=10 or so F. I have defi gauges, so its quite accurate. 90-92C running withot AC, 85-86C with AC on. Any ideas on why is that?


also does the compressor goes off at certain RPM or Full Throtle?

 

the secondary fan is probably kicking on when the A/C is triggred & while im not familiar enough with the EVO's routines, most every manufacturer disables the A/C compresser when the TPS is over 90%
