One important thing is the top 2 bolts---they are "shorter" than the rest!
Failure to re-install them in their correct place will damage the timing gears!
When re-filling the coolant...loosen one of the heater hoses at the firewall and be sure the hose is actually loose/free....this will aid in bleeding any air from the system...after starting wait till coolant seeps from the loosend hose before tightening the clamp.
Fan hub threads are LEFT hand...others will chime in as to their favorite way of removal tool choices that range from a BFH and punch to air chisel to the correct fan hub tool that you can buy for about $40
Hope this is of some help
