I have a really bad leak coming from what I believe to be the crankshaft pulley seal. Could someone tell me if this is something I could do myself and directions on how to do it? Thanks! Ps its a 2000 5.9 with 210k miles.

 

If you are talking about the front crank shaft seal then you need to first remove the vibration dampener (front pulley) with a remover, then remove the water pump, then the timing chain cover. This will get you to the seal.

 

Is it hard to do myself? Would I have to remove the radiator also?
