Yall, I have a 2003 Tiburon GT. Don't have any issues with the car at all, but opened my radiator cap and this is what I found...like I stated, the car is running to perfection! No heat issues or anything...

Coolant swap....

Replace the coolant.

Also, it's worth checking the oil on the dipstick too.

Its old coolant. Recommended coolant change is usually every 5 years. Hyundai usually have green coolant. I run Prestone in my cars no problem and with distilled water. To get a proper and full coolant change and have all the coolant released from the bock, I do a coolant change while I do the timing belt. Because then I can change the water pump, which frees all the old coolant out the block. Thats something you can look into too.
