I have noticed that the aux fans come on every 30 seconds or so when the climate control is on set at 70 F , outside temperature is 34 degrees and engine temp is 85C or more .


I will see if they are constantly running when engine temp gets higher.

I do not think engine temp gets higher than 83C even in traffic under normal accelration.

If I recall correctly it goes to over 100C when I am testing the car by accelerating aggresively over and over up hills etc to test for the hesitation that I have .

I dont know if they come on because compressor comes on , but does compressor come on under those condition to remove humidity ?

I am going to go drive around normally now, highway and city and record where engine temp goes, and if the fans come on at those temps ?
