tomorrow I'm going to attempt to install March underdrive pulleys. My mechanical experience doesn't cover much...changed my oil numerous times, cleaned MAF, replaced fuel filter, replaced/cleaned K&N filter, removed silencer (oh boy)...thats about it, the rest I did with other buddies.

My question is should I look into getting some assistance from someone who has done it before, or just go ahead and tackle it with help of another novice mechanic? Also, my car has 52k miles, should I replace the belt?

 

I didn't have to change my belt.
