a buddy of mine tried to help me out this morning and set me further back. he broke the bottom bolt off in the thermostat housing!!! :icon_evil . can the housing come off the block or do i have to take the fan ,shroud,and radiator out? it has to be drilled and extracted or even tapped. i have acces to a lefthand drill bit set,and a set of easy-outs but not till tuesday(bummer). any ideas on what is the easyies way to fix it?
