Went to install a Mishimoto 180' thermostat & RacingGlass Radiator hose insert and found this: 2014 SRT owners manual states that only "OAT" formulation coolant/anti freeze should be used, and that it should never be mixed with "HOAT" formulation coolant/antifreeze......From internet research Mopar's OAT coolant is deep purple in color, and their HOAT coolant is a Redish Pink color....Further research says that Fiat Chrysler changed over to the OAT coolant in 2013 almost across the board..... so went to local dealer to purchase a gallon of the OAT coolant, the parts guy checked my VIN number and confirmed that my Jeep should have come with the PURPLE OAT coolant from the factory as that was the correct fluid for my 14 SRT.... Took the Jeep over to the service Dept. and had one of the service advisors inspect my coolant overflow tank and confirm the type of fluid in my car, as I thought it looked awfully reddish/pink to me, He said oh no, thats really the Mopar purple color it just looks that way...... OK, so I go home and start my install and guess what,
not only is the coolant really reddish/pink, but under the radiator cap, and in the overflow tank its all brown and goopy and thick, like mud, and at the bottom of the overflow tank....Now my Jeep only has little over 7 thousand miles on it, it was purchased as a brand new vehicle, and to my knowledge has never had any work on anything that would require new coolant or even added coolant.....
so I'm really wondering how the wrong coolant got into my jeep, and from the goop forming, it appears that somewhere the OAT and HOAT were mixed in my car......So $80.00 later, cost of 4 gallons of OAT coolant at my dealer, a few hours wasted flushing out the system, I think I now have the right coolant in my Jeep......anyone else ever check there coolant/anti freeze color??????
If not you may want to do so.
