Bearings are starting to go in my water pump, got some slop in it. Never done a threaded on fan before so no tools for it. Is it worth the extra bucks for the pneumatic wrench? Looking at a set for $115 on Amazon. Relatively quite a bit more than a regular wrench, but far cheaper than a new radiator or getting into the quality issues these days when my brass radiator works fine and doesn't leak. Thoughts?
