    I just got a 2017 Grand Cherokee. I noticed when I am in park and idling, every few minutes the radiator fan revs up for a few seconds. This seems to occur when the AC is on. Is this normal?

    Parked or idling with the AC on will raise engine temps and usually trigger the radiator fans to cycle on and off. Scheduled replacement/flush of the cooling system is good preventative maintenance. I prefer to use OEM coolants whenever possible and avoid mixing coolant types.
