dealer did mine in 4.5 hours.....he had all the tools and resources right there to make it go quickIf you have an auto trans you will need a special tool that goes in place of the starter to hold the flywheel kent moore makes it cost $100. starter will need to removed and slid back as far as possiable. I also took out the drivers side inner fender well to access the bolts on the rear of the water pump. Getting the fan off is a pain as well used a craftsman rubber strap wrench to hold the pulley. total time was 6 hours. you will need o-rings also. do a search for the part numbers they are on this site.
