I have an L4 83 camaro and I'm replacingthe water pump, but I can't get the bolts off of the old water pump wheel. I got the pulley and the fan off, but I can't get the double sided bolts off of the old one so I can attach the fan and pulley to the new one.
Any help?

 

spin two nuts on one stud, tighten them against each other, then use a screwdriver between two other studs(they are studs, not bolts) and use a wrench on the bottom nut and they should come right out, loosen them all this way first(so you can still use a screwdriver to hold it) then when they are all loose, take them all out(once they break loose, they should screw right out, not always, but most of the time)
