There is a hole in the top of my radiator. I was still driving my camry around but had to stop when it started to run hot. I just purchased a new radiator. How difficult is it to replace. Do I need to do something to prep the vehicle and how many people and hours will it take? Thanks.

Drain, remove, and replace--1 man 1 hour. Not hard at all. Good time to replace old radiator hoses. Refill with a 50/50 mixture of the proper antifreeze and distilled water--be sure to remove all air from the system.
