Also, as part of the maintence, i like to replace the water pump. However, I see that one of the mounting bolts is behind the big harmonic balancer. I don't see a way to loosen that bolts without taking out the cooling fan bracket (that will make me to take out the alternator) and the harmonic balancer. If I am right, is it worth it to do? Or should I wait until the water pump fail?

On mine, the damper had to come off to get the last bolt out of the waterpump. If you take the damper off, you will be disturbing the main crank seal. The bolt is a 27 mm bolt that I was able to loosen with a floor jack under a breaker bar. Unless you have a fancy crank lock tool that they use at the dealer, your second option to stop the crank from turning when you try to loosen and tighten the crank bolt is to take out one of the three torque converter bolts and install a long bolt with some sleeves on it to hold the flywheel from turning when you loosen it. In this link I posted a picture of the makeshift crank lock. 1989 560 Sel Water Pump Need Help
There is a special tool that MB has to install the new front crank insert and seal which makes it really easy.
