Replacing Waterpump on 98 Acheiva

[Hybrid1990crx]

The waterpump on my g/f's car just took a shit and I'm wondering how hard it is to replace it. Its a 98 Acheiva. What tools will it require me to have, and what is the process? What would you guys rate this in difficulty from 1-10? 1 being easier and 10 being the hardest. Thanks guys.

Yeah that helps alot. But that serpentine belt confuses the crap out of me. I looked down to see where the bolt is for the spring tentioner and it looks like it is going to be a bitch to even get to it with a breaker bar? The serpentine is really what is making me not want to do this. I don't understand why I even have to take the fucking off, since the waterpump pulley rides on the outside of the belt. The shop near my house said it had to come off, and even be replaced because of the coolant that got on it. Couldn't I just take it to the car wash and use the degreaser blower on it?

All you are going to do is move the tensioner (it is spring loaded) to remove and reinstall the belt.
Spend the extra bucks and replace the belt
