Having now got to a point after 4 months of ongoing problems, where i am going to set fire to the car, it occurred to me to try just one more thing.... My Grand Picasso 1.6 petrol just boils up after a few miles.. initially we were told it was the thermostat, this subsequently was replaced, the problem continued.. new pump and actuator, new header tank cap (2 actually) all to no avail.. finally 3 days ago a new head gasket with all the problems (costs) that are involved with fitting one....... and it still boils up throwing all the coolant out of the header tank !! Now on examining the car i have noticed that it only seems to be the top of the radiator that get hot, the bottom hose is always cold, this would indicate to me a circulatory problem, that the thermostat is not opening allowing for the engine to cool, but after having it replaced you would assume that it was ok ? Is there a setting within management to dictate the operating temperature ? Can the thermostat be set open permanently ? The cooling circuit has been flushed countless times but am i missing something ? Any advice would be greatly appreciated.. because i am totally soured now with Citroen...
