Drain the radiator and remove the two block plugs. One doubles as the knock sensor, and the other one is on the driver side (small square plug). Pop off the oil cooler bypass hose off of the bottom of the radiator (bottom driver side) and you're good.
Put whatever coolant you have now in (green or orange). Just don't mix the two.

If you have pets, make sure to keep them away while you do this, antifreeze will kill them quite dead.
Reseal the plugs with either pipe dope or teflon tape, and put them back in. Put the lower hose back on.
AllData says my '96 has a capacity of 15.1 quarts (just under 4 gallons). Be sure what you put in there is a 50/50 mix with water.

Honestly it doesn't matter what coolant you put in. Just make sure that you completely flush out the engine if you are going to put in different coolant. I used Dexcool just because that is what GM recommends, but the green stuff will work just fine.

i think the reservoir(long tube) is for topping off or just extra in case you loose any. There is no mark just make sure there's some on that dipstick. Also make sure you bleed the system when you are done.
