front main is time consuming but not difficult. As a matter fact after the third time (I messed up the tension first and then the belt slipped) I was able to do it in 1/2 an hour... <img src="/forums/images/graemlins/drunk.gif" alt="" />

But seriously, if you tackle the front main make sure you have plenty of time and a manual. The hardest part is torqueing the front crank bolt and lining up the cams.

If you do go for it, no need to pull the radiator and if your AC doesn't work don't bother putting it back, that will save you 1/2 hour.

I would pin point the leak first.
