Exactly how hard is it to change out a waterpump & all the other goodies? Or should I just stick to the waterpump & have someone else do all the other stuff like the timing belt cam/crank seals, tensioner ect.?

I know it makes sense to do everthing at the same time, but the thing needs to be changed & I dont have much $$.

Your help will be going towards keeping one more nice maxima on the street. Thanx
