You'll need a handheld tuner to change the fan settings.Ok,I know you can modify them but how?
I wouldn't use a universal coolant. Check your owner's manual to confirm, but your car should have come from the factory with HOAT coolant. Chrysler Pink HOAT isn't very expensive, but if you want to use something else, I'd suggest a good HOAT concentrate like Zerex G05.And also I bought some AutoZone universal coolant it says mixes with any color! For all makes and models. I plan on draining the system and flushing with water.will this be ok using that coolant?
Since you've no way of knowing what the previous owner(s) put in there, you should flush the system first with distilled water.
