    I have now swapped the two sensors, I have not put any loctite for the moment, I hope it will not sink during the test (this week)...
    I await the result of this change, I will also swapp the wires and study the results.
    I believe the problem is air in the cooling system., I will Get the plane in a nose down attitude to eliminate ,Ihope,all the air.
    it is a new plane and new engine (never flown) . I believe that there is not enough coolant in the system,but it is difficult to know that;
    i will write you the results,thank you

    Swapping wires could have been done on the ground and at least ruled that in or out. If you have a few hours of flight time on the engine I'll be surprised if it was air in the system. Just my 2 cents for a wager.

    the engine is new,never flown and this is the first time I fill it with coolant;

    I will swap the sensors: first operation and I test 30 seconds runing
    I swap the wires: second operation and I test 30 seconds runing
    I get the plane nose down at the end and test 30 seconds ;
    the radiator is obove the carbs and expension tank is below the engine on the S6 coyote...
    I hope it will be good! thank you
