I took delivery of a '25 quad cab 4x4 with the Hurricane 3.0 two weeks ago and have questions relating to two issues. Firstly, the high idle time with a cold engine seems excessive to me. At relatively warm ambient temps (80'sF), and a cold engine, the engine will idle at 1500 rpm for ~1.5 mins before dropping to 600-700. At slightly cooler ambient temps (60-70's) the high idle at cold start can be as long as 5 mins before dropping down.
The second issue is with the operation of the radiator cooling fan. At highway speeds, or with the AC on, both coolant and oil temps stabilize at 195-200F. At slower speeds and with the AC off the coolant temps approach 220F before the fan kicks on, and it stays on only until the the temps drop slightly to 212-214F where it turns off again, and the cycle repeats. When it does turn on at the higher temps it is not running that fast (not as fast as with the AC on). It seems to me that it should be moving as much air as possible at those temps.
Just looking to other Hurricane owners for their observations and experiences. Are these behaviors normal or is something wrong with my truck? Thanks.
