    Has anyone else had a problem with their hellcat overheating? It is at the dealership now but they said they see that it is overheating but don't know the problem. seeing if anyone else has had the problem so that i can point the dealership in the correct direction. I already told them to check thermostat.


    Thanks,

    Wanz

    Can you tell us what year your car is? The 2015's had some issues with radiators and hoses.

    Hi Wanz, a few owners have had issues with the cooling fans failing to work as they should

    Interesting. I was at my dealership last week getting pul changed and they had a brand new 2016 they were working on and I asked my he mechanic what he was doing and he said it had a cooling issue. I'll have to ask them what the deal was.

    EDIT: 2016 Challenger Hellcat

    Hi, I just got home from towing mine to the dealership for overheating. It had been at the detail shop for 3 days getting detailed and a full clear bra put on. Leaving the detail shop I noticed the temps rise above normal and the cooling fan came on. Temps rose from normal 205 to 220 or so. I attributed it to maybe the 80 temps we had today. I drove it a couple miles before entering the freeway where it was stop and go for about 5 miles. During that period temps rose to 230 and came back down to 220. Cooling fan on the whole time. Then after a couple miles of stop and go the temps hit 250 and the small check engine overheating light came on for about 15 seconds and then the temps dipped back down to 240 and the light went off. I had an exit about a mile away and was getting off when I heard some banging. Actually felt it through the firewall and brake pedal. The temps hit 260 and the entire center display turned red with a large engine overheating warning. By this time I was at exit and when i came to stop sign to get off it started running erratically. I coasted into a gas station about 100 yards away. I let it idle hoping the temps would come down but after 10-15 secs they were hitting 265-270 so I shut it down. I heard terrible boiling noise. Looked under the hood and there was zero coolant in the reservoir and a stream of it where I had parked directly below the reservoir. I called roadside assistance and had it towed to the dealership. Unfortunately the service dept had already closed but they allowed me to park it inside as it crunk up fine after I got it off the tow truck. The salesman that sold me the car said it sounded like a loose hose had finally busted or come loose. The coolant temp and oil temps rose to 270 or so. I really hope nothing internally is messed up. Do you guys have any clue as to what happened or possibly anything I should ask or tell the service department tomorrow when I call in? Thanks.

    my 2015 had the main fan connector get water in it, the fan didn't come on and it overheated to 249, the dealer applied dielectric grease to the connector made a plastic shield to protect it from water in the future, it has not overheated since.
    but it does go to 220 regularly before the fan comes on which is incorrect,
    the electric fan is designed to be infinetly variable in speed. so it should spin fast enough to keep the motor at a constant temp and spin faster if temps rise. What mine does is the fan goes on high when the temp reaches 220 and then shuts off, it doesn't work correctly IMHO.
    If the motor overheats and blows, oh well, new motor time.
    I'm tired of thinking about it.

    self diagnostics: good old days. start the car, remove radiator cap, watch water level, look for air bubbles. Don't know if it would work on the HC but worth a try. also make sure the coolant pumps are working, and check for air lock in the hoses (feel the hose(s)...when engine is warm a cooler hose indicates no or less water movement). I personally don't like taking any car to the dealer; however, as I get older I don't really enjoy crawling around on the ground either. Hope you get it fixed quickly so you can enjoy the car. :)

    My 2016 had the exact same problem with only 100 miles on it. Had to have it towed and the dealer found the same water in the connector issue. They were baffled as to how it got in there but it's been fine since, after they did what your dealer did to fix it. They did open a STAR case on it.
