well i was looking at the motor today while it was running and i notice that the belt looks like it is trying to walk off the pulley on the bottom of the motor. i was watching the belt from the drivers side and it looks like it is wanting to try and come off going toward the front of the motor.
this bottom pulley is on the crank shaft, so they go bad.
i cleaned all the pulleys and that helped. it is running true except for then i rev the engine up.
then i rev the motor up i notice the belt will squeal a little and wobble a little but it will go back in place on the pulley and run smooth.
so far i have changed the water pump, fan clutch, upper idler pulley, lower idler pulley, and a new belt.
the belt is starting to wear a little with it rubbing on the front of the crandshaft pulley.
if anyone has some ideas i could use them. thanks in advance
