What temp does your engine run at?? Lately (with the 3 fans running) mine runs at about 96 degrees when pushed for 10-15 mins. I'd rather this around 86 degrees.
Frankly, I have no idea! (If I hook my temp sender up, my gauge goes straight to the top and stays there...Need to (A) Extract old sender and (B) install new one...
Having said that, the car seems to runs quite cool in driving, and I only notice the fans coming on when the car is idling stationary...They'll cycle on for a few minutes then cycle off (when the temp drops to 85 degrees - Or at least that's the way the Autronic has been setup to cycle them!
