What type of coolant to use in a 1999 Dodge Intrepid?

Answer 1

HOAT (Universal) Antifreeze purchased at any Wal-Mart which is a combination of IAT (green) antifreeze and regular OAT (usually yellow, red or orange) antifreeze. Chrysler started using the universal stuff after a short experiment with GM's "Dexcool" (OAT). I used dexcool in my Intrepid because I had leftover from my Chevy Malibu of the same year because it was the same color (orange) and nothing has happened yet but the color of antifreeze is just a dye and shouldn't be used to determine the type of coolant you should use. I had no manual but I figured it out by researching online. I recomend flushing the radiator first as well before switching to regular green (IAT) antifreeze or you could even use 10% green and 90% OAT to make your own universal HOAT antifeeze (Hybrid Antifreeze) which is only a combo of both IAT and OAT antifreeze. Hope that answers your question.
