Based on this, the starcool should only be used when necessary or on shore power with the engine off.
Marty I was told the problem is that the coolant (whatever it is these days) is used by both systems. If you don't run the starcool while using the front AC the starcool seems to hog the coolant (even if its off) and the front stock system and ducts gets warmer up front. Turn the starcool on for a while and the front gets back to normal. I thought there was something wrong but it was me.
On a side note, I had the stock AC loose coolant due to a leak. The starcool ran fine and the front failed. It had SMB scratching their head. I asked about a check valve and did find one so that can happen.
