I actually had my motors replaced under warranty,but love the set up. In the winter it can't be beat. I pulled my alternator today without touching the fans. Here is the trick. After removing belt, take long bottom bolt out about two inches. Cut with hacksaw or die grinder. Remove bolt, After replacing alternator but new bolt in from rear, I used stainless.
Its M10 x 1. 50 Four inches long. Works like a charm and less work!
