Just look in your owner's manual. It should say what type of coolant to put it. 98-02 models shouldn't need anything special, they only started doing that around '05ish on. If it's not a special type of coolant, then just use the green type antifreeze. You do not need to buy it pre-mixed. You can figure out the capacity of your engine through the manual, buy straight anti-freeze and pour half the capacity antifreeze into the radiator, followed by then pouring water until full. You'll save a little money that way.
If it does not say to use a special coolant then don't waste money buying the "safe for aluminum" stuff. Normal green antifreeze will work here.
