    - please post your leak issue (if known). whether it be blown rad, loose clamp, leaky intercooler (inside supercharger) or just smell of coolant.
    - please post your build date.
    - please post your mileage.
    - please post your in-service date. (date of first use)
    - please post a brief description of conditions when leak/symptom occurred.

    build date can be found on vehicle certification label on driver's door.
    look for DATE OF MFG: month-year.
    look for MDH: month-day-hour.

    this thread is for research only. please refrain from posting if you have no coolant leak issues. I am trying to keep discussions out of this thread. thanks.

    my guess for root cause: pressure cap.

    see CatBurghlr's post below for best reply format.
    thank you for participating.

    Blew all the coolant out of the car at 4k in 2nd gear. Car at 170 deg f. Plastic end cap on passenger side of rad blew completely out of the rad. I smelled a strong coolant odor one time for about two minutes, 250 miles prior to my blow up.

    This should be done for any issue that seems to be repeating.

    I'll reply as soon as I have my car in my possession and have some data to share, positive or negative.
    This needs to be addressed.

    Had mine for all of about 10 mi , less than 20 mi on odometer. took it to the auto parts store to get a fire extinguisher, flashlight, etc. I came out, feelin' real good about myself and the amazing piece of machinery in the parking lot, when, after I fired 'er up, the guy that I was parked next to was trying to get my attention, by pointing to the large puddle of antifreeze that had accumulated in the spot that I had just backed out of. Long story short, 1 hour later, had it towed back to dealer, nearly all coolant bled out. Apparently the culprit was a return line to the coolant reservoir, even after the mechanic reattached the line with the clamp, as soon as he pressurized the system, ie., started the engine, the hose would pop off through the fitting, and clamp. The mechanic, (an SRT guru!) was in contact with FC, and reported both his problem, and the fix he came up with- (essentially double clamps, as there is no raised ridge/nipple on the fitting)
    FC IS AWARE-,as he told me he was in consultation with them the whole time during the repair of a brand new, just off the truck car that became undrivable after 10 mi.... they are aware.

    If anyone has similar problems, i'll be happy to forward the SRT specialists contact info, I just don't want him to be deluged with phone calls while he's trying to work. VERY smart guy, and FC is DEFINETELY aware of the problem, AND THE FIX!!!

    BTW-LOVE the car!!!!!...I know...."Other than that, Mrs. Lincoln, how did you like the play!"

    Regards

    I received my Challenger Late Feb 1200 miles now getting 0307 number 7 cyl misfiring and a I/C cooler low message. I smell antifreeze occasionally on cold startup. Took to dealer to clear codes and was told drive until problem arises. Code came back both cooler rad tank correct level and overflow at bottom. The I/C message continues to come up now and ten and 0307 code will clear if a drive 20/30 miles. Anybody got any ideas.

    It will interesting to see if you have any blown seals in the SC or in the motor.

    Issue: pin hole in lower corner of radiator near one of the vertical end-cap tabs.
    Build 705/ late November 2014
    3557 miles
    Radiator replaced under warranty 4-7-2015
    Noticed a small coolant puddle on the floor under passenger side front bumper. Took the gamble, drove it 3 1/2 miles to dealership and won. Would have had it trailered if it would have been much more than a couple tablespoons on the ground and if the reservoir had been low.

    Just curious to know if FCA pulls such warranty info. from the dealer network i.e., through the field Engineers who subsequently escalate such critical concerns to the NPD or Sustaining Engineering teams for further review?
