2012 Grand Cherokee LTD 5.7L - white liquid spray in engine compartment

33K miles. Just started to notice this, accompanied by weird noises in engine compartment & vibrations at floorboard. Seems to occur when coming to operating temp > 200 degrees F. Saw posts about Thermostat, some recommending after market 180 degree F replacement. Also saw a post on water pump needing replacement about same mileage. Going to make dealer appointment for pressure test, coolant flush. Other Ideas? Thoughts? Thanks!

Re: 2012 Grand Cherokee LTD 5.7L - white liquid spray in engine compartment

Well I never experienced any noises or vibrations but a year or so ago with my 2011 Laredo X with maybe 20,000 on it, I wanted to show off the engine compartment to someone and when I opened the hood I was floored... I had the hood open 2 days earlier and all was well and this time there was this white fluid type crap that had been all over the front of the motor and on the engine cover ?
I cleaned it all up and tried to figure out what is was but couldn't. I know the wiper fluid is blue and the anti freeze is whatever ( but not white ). I thought maybe it had something to do with the ac ? I then thought maybe some scrub at my work tried to sabotage my ride by squirting something through the radiator area. ( that's where the fluid was, directly in the front ) I then had to deal with my OCD and open the hood every day to check for it and never saw it again ...... ????
I'm interested in what the dealer will tell you......

Sorry for the late update, but here is what happened. The water pump was blown. White spray that had solidified inside engine compartment probably over heated boiling coolant stains. My 3 yr / 36K mile warranty was about up, but as this is a commonly known issue with these on the 5.7 L Hemi's, it was covered by warranty.

FYI, your 5/100k powertrain warranty would cover it.
