I've owned my Patriot for 2 weeks now. With the heatwave here in Chicago this weekend, I've been using the AC a lot. After driving in stop and go traffic with the AC Running, I noticed when I parked that there was coolant leaking from my vehicle, I popped the hood and noticed that it was spewing out from the radiator cap, and the reservoir tank was empty. After letting the radiator cool down, I noticed that the radiator cap was halfway open. I don't know if it was left like that at the assembly plant, or at the dealer. I never bothered to check it since this is a a brand new car(big mistake). The owners manual recommends that the only coolant used with this car is Mopar (HOAT) Hybrid Organic Additive Technology 5 year coolant. I checked Pep boys and O'reillys, and they don't have this coolant. Am I stuck going back to the dealer which is 20 miles away just to get a couple gallons of this coolant with my other vehicle since I can not drive my car with very little coolant for 20 miles in 95 degree heat, or will any coolant from my local auto parts store work? Please advise.
