    It seams there is no coolant circulation, one side of the radiator is real hot and the other cold.
    Now the radiator just came back from leak and pressure testing- the say its OK,
    waterpump, is new, thermostat is new, coolant reservoir new. There is no water in oil, and no oil in coolant., but system building up pressure until overheating.
    Its kind of mysterious, please assist if you had similar problems.

    Did you test the new thermostat in a pan of hot water before fitting ?

    Thank you very much for your quick reply, but the thermostat is removed for that purpose. (it overheats with and without)
    It looks like no circulation, but what can stop the circulation? (water pump is new, radiator tested)

    Model year 2008, petrol V8, Vin SALME15478A288408, when we test the overheating we do not put a thermostat, the temp here is always 30-35 centigrade.

    Are the current problems the same as the problems pre-repair? If not look at your new parts.

    Drain the coolant system, disconnect at some point you can introduce and capture water, hook up a water supply source to introduction side and put a bucket on other side and try to flush the system. I once bought an engine for an Audi A8, found a rat or mouse in a coolant hose.

    The heater is not getting hot, strange, maybe the heater valves are not working, since the heather is never used here.

    That sounds interesting, we have many cases rats eating wires, will check and flash. Today we unstall a new radiator.

    Problem solved, we had the Radiator at a Radiator service for cleaning and leak testing, they said its all OK, but no circulation and the rat gave me the idea that something must be clogged.
    So we replaced the Radiator today and the car is running fine. Thank you all for your kind help!

    Good show, do you run anti freeze in your system as although you don’t need it to prevent freezing it still protects the system from corrosion?

    Of course we do, even in the Tropics, it protects, lubricates your system and runs cooler.
