It started when I noticed the tachometer wasn't showing the proper RPM's and the Gen light stayed on after start. Looked into it and found the fan belt was loose. While adjusting the fan belt I noticed the fan seemed loose and could be wobbled all around yet no leaks of coolant. I was hoping it was just the four fan bolts but knew it was more likely the pump going bad.
Sure enough the pump bearing is shot but surprising was there was still no leak. I did find the bottom weep hole was completely blocked with rust and dirt.
