Well I think I may have found why the fuse blew. I just took it for a long test drive after all the head gasket and fan work to see make sure it was road worthy and an aweful noise began to shreek from under the hood. The larger fan was making a roar and clunk sound and was spinning on and off irratically. Obviously this fan motor is on it's last leg and will be replaced soon. This leads me to ask, would a fan motor locking up on and off like this make the fuse blow? To me it would but I want a second opinion.
