Also make sure you have a large enough alternator to handle the amp spike when the fans kick on. That can also cause accessory load issues as several of the front drive kits out there only come with 140 amp alternator or less and that won't cut it.

Mike Im gonna check the pressures for sure..... good point! Also gonna load test my alternator and see whats going on? Im running a factory corvette alternator as well as the accesory drive.
Thanks guys!
