post icon 85 subaru-water pump pulley Sign In

I have a 85 Subaru wagon. the pulley for i believe the water pump has come loose on my wagon, all the belts were loose and it caused it to over heat and loose power steering, today i pulled all the belts off, tightened the pulley put the belts back on and tried to start it. Started okay but almost immediately i noticed the pulley was loose again. Any idea why it keeps coming loose, is the pulley bad or something internal, not letting it tighten properly? all the help will be appreciated. thanks

lost in albuquerque

Is the waterpump bad itself? Check the loose pulley for what it mounts to for the problem,

as far as i know the pump is fine, it may not even be the water pump pulley, not sure no manual, it looked like it bolts into part of the timing belt, i could see part of the timing belt anyway when i pulled the pulley off

Whatever that pulley mounts to -- an idler or whatever seems like the problem. If it doesn't tighten up there might be some stripped threads, loose bolts or something you should be able to see,

it does tighten up, until the car is started then it comes loose right away, im thinking its the main pulley not the water pump

Is this pulley the harmonic balancer? That would be the only one that would turn with nothing attached as it is right on the crankshaft. They are rubber isolated unseen and could have failed. I don't know of that as common but sure needs looking into,
