I replaced the rad on my 97 850 5spd with help from a friend. It was time-consuming but NOT impossible. I bought a Nissens from FCP. Then, a few months later, I had to replace the rad again due to a front end collision. We pulled a rad from the JY and it was super easy to remove and put back in. 7 Months later its running just fine.
I'm a girl and had never changed the oil on a car before. Between the Haynes and Youtube, we made out all right. No, I didn't just watch and hand him the tools. :P
