[QUOTE="Piotruh, post: 441389, member: 22202"] Thank you for information Generally I have same symptoms of loosing ( actually loosing of coolant) I tell you my story JKU 2017 3.6 L 42000 mil Founded losing coolant from reservoir tank (Jeep from USA ME coming to Poland on 2021 March 15) Added 1 ltr of coolant ( pink colour G12++) I did not change from now. After driving on the city level fall to min again, added 0.3 liter Driving on high way over 660 km nothing , no leakage Continuos driving in the city the same problem need add 0.15 ltr again. Engine area dry ( super dry), I did not observed any leaks from connections or hoses clamps. In passenger side cabin dry. oil in engine colour and level normal. Sometimes during start and run engine (cold ) not very smooth work of engine but almost imperceptible I checked during this long trip cap from radiator found in perfect conditions but I Little move it the spring ( maybe cap?!) No white smoke observed during start engine from cold ( 15C ambient temperature) time to time comming very small white smoke like from cigarette but very, very small. No any abnormal smell observed. Only when Im driving in the city temperature of working engine ( coolant) is from 89-107C ) - during high way or similar way 89-98C is that normal parameters? And I observed that loosing coolant is only when I m driving in the city ( during traffic etc.) - high temperature more that 98C In October I will make exhaust gas test for coolant present we will see what will be the result. What you recommended to do?! -Change coolant for ex PRESTONE completely? - change thermostat ? ( top hose after 10 min working engine is not hard ) I can squeeze hose, it is hot. radiator fan in my jeep have only one speed I did not observe high speed I will be grateful for the feedback Regards Piotr [/QUOTE]
