Dexcool is the red antifreeze and is prevalent in GMs. Our cars take the "regular green" antifreeze, mixed 50/50 with distilled water (or buy premix). Don't waste money on Hyundai brand antifreeze...if you do, I'll send you my address and you can send me checks too! :P
Having to add a small amount after 32,000 miles of driving should be no problem, although it is always a good idea to keep an eye on ALL fluids on a regular basis (brake, PS, trans, coolant, oil).
Tranny fluid should be flushed every 30K. Brakes flushed every two years regardless of miles. Coolant and PS flush every 2-3 years. Oil change every 3-5K miles.
