Poolman,
Check out the site: http://www.autoacforum.com/ . It's got great info about AC.
I really recommend that you do not refill your system without knowing the high side psi. I'm very new at this stuff, but from what I've heard, if you overcharge then the cooling actually goes down and it will eventually ruin the compressor. The above site (autoacforum.com) recommends that you vaccum out the old coolant and oil and then recharge.
With my Grand Caravan the specs on it are listed below. I have no idea if are simular to a S90's PSI's.
Hope this helps.
Best Regards,
Stan
