I'm trying to change the water pump but the bolt that sticks up that holds the distributor is in the way, how do i remove it ? Also i cant seem to be able to remove the bolt all the way at the bottom, it seems like the engines v belt ( where it spins alll the v belts are) is hitting and wont let me remove that bolt as well ! any thoughts ? i know theirs 2 holes on that 'fly whee' i tried one hole and the bolt hits the fly wheel there soo im moving that big thing so i can get to the other hole....any thoughts ? thanks !! btw
