it has a very slow leak, i havent noticed any water actually coming out but i notice a drop in the resorvoir from time to time, i dont know if this could be from the car getting so hot it evaporates or not.
i have replaced the thermostat, and i think they had a pressure test done on the radiator and a compression check on the cylinders, however im not sure about either.
it does not produce any smoke out of the exhaust, which is a sign i always use check for head so... i dont know, im not pro. just dont think thats the cause
the biggest mystery for me is why it is so seemingly random?
It's usually an air bubble in the system. If they did a pressure test, they may have left air in the system, and it will cause your engine to overheat when it hits certain spots in your system.
Could be head gaskets. check your oil.
Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion.
