    That hose loop and that second temperature sensor are for the exhaust heat recirculation system, which I do not think is used in all market regions.

    I wonder if it is present in Lithuania. Does the exhaust arrangement under the car look like this (note the two coolant hoses)?

    No, my excaust system is very simple, just catalytic converter ant two pcs lambda. Ok thanks for the info, that's mean in the EU we don't have this exhaust system.

    Post #35 may have some red herrings in it. Replacing the faulty water pump was certainly important in solving that problem.

    There are some rituals being circulated that make filling and burping the cooling system a lot more complicated than what the repair manual says to do, and what's in the repair manual has reliably worked for me.
