Hello,My car overheated, the cause was the thermostat, it was replaced and everything was fine. Now, on the way back home, the same thing happened to me. .I smelled some smell in the cabin, I can see it starting to smoke. I opened the hood and it was smoking near the turbine, there was also oil (I didn't notice that it was there before) and probably because of the high heat, the oil was burning. I left it for about an hour to cool down I pour water in the bottle (unlike the first time, this time there was no leakage of liquid on the right wheel when the thermostat was broken) to note that there was no boiling of liquid in the bottle, I opened the cap of the bottle slightly, there was no pressure compared to the first time when the antifreeze was ticking. I start the car and continue, turn on the air conditioner to the highest temperature and everything is fine for about 50 km. I also noticed that the air conditioner started to cool, not heat, and again the same situation. I wait a little longer this time and somehow I get home .The next day, if I take the car to the mechanic, it won't start. I'll call a tow truck and I drive it to the mechanic. Somehow he turned it on, he says that it started on the third cylinder, the diagnostics shows nothing.
He checked the thermostat, it works as it should. He checked the turbine, he says it's ok. He cleaned the hoses that were full of oil, added fluid, it starts normally now, it reaches temperature. according to him, he focused on starting the car, not on the cause of overheating.
I am asking for your opinion, help, advice on what could be the cause of overheating, if something is not clogged? Thank you

 

There may be more than one problem.

If the turbo charger has a lubrication system problem, that could be the reason for oil all over.

Does the HOT light come on or does the engine temp gauge show very high temp?

If you turn the HEATER on it will take heat from the coolant and blow it into the vehicle . Turning on the A/C adds to the problem and causes the engine to work harder.

Need some more accurate info,plus if, it is actually overheating ,there could be several reasons . Before going into an unnecessary explanation please provide answers to the above questions.

The mechanic contacted me, he told me that the coolant bottle was cracked and that the most likely cause was that the pressure in the bottle could not be created.
