It's really easy once you have the pulley off. You just pry out the old seal, carefully so you don't damage the housing. Tap in the new one lightly as not to damage it. Some like to add a bit of silicone to the outside of the seal to make sure it seals up. This is fine but don't overdo it! It is also good to put a small bit of oil on the rubber part of the seal to lubricate it. This helps prevent a tear in the seal during installation. Above all be patient! I've seen more cars messed up because someone was in a hurry. Good luck!

the thinner oil has less resistance to flow and untimately reduces fuel consumption. A common misconception is that thin oils have low film strength when in-fact that is not true. Formulation of the oil is mainly what determines the film strength.
When you install a new seal or install a DMD not only should you apply oil to the seal but also to the sealing surface of the damper.
When installing the DMD or the stock crankshaft damper or under drive pulley the keyway must be sealed as well with oil resistant silicone (carefully select your silicone sealant, some are only rated for intermittent exposure to oil, you need one that is rated for continous exposure to oil, usually the balck and blue colored silicones are oil resistant)If not sealed oil will seep out through the space between the key and the keyway slot.
Thanks for the tips guys! I figured it would be fairly easy. I think I can handle it.
As for what type of oil I use, I hesitated to even post that 'cause I knew it would become another "oil debate thread", and that is the last thing I want to start. I've read countless threads here about it and I don't want to start another.
Thanks again guys!
