Hey guys, so im in a bit of predicament right now. My 1997 pathy has 160k on the original timing belt (prob a time bomb just waiting to blow) and is leaking coolant from the water pump. I've been trying to get this taken care of for the apst couple weekends but keep running into trouble. Right now I was trying to take off the harmonic balancer pulley, and one of the bolts ripped out and took the threads from inside the pulley with it!! What are my options now? Should i attempt to re-tap the hole? Would it be at all possible to use c-clamps and clamp the puller to the pulley and take it off that way? Also, this is prob a dumb question, but that section is 3consecutive pulleys, do they all come off together? ANY help or tips would be great, my areas calling for snow next week and I need this thing running. I commute to college, and what i drive now is a supercharged FWD car, so i'm not going anywhere in the freaking snow...Also I was curious, if I were to use clamps would ti be ok to clamp behind the middle pulley? Just using my hand, the two front pulleys started to come off a bit together, but I thought all 3 of them were attached? Are just the front two attached to eachother? I dont really get how that works, if someone could help me i could really need it...
