Booked car in garage in febuary for head gasket and new timing belt was told my cam was worn so got a new one fitted. Got the car back and was told the starter motor was broke (twat to start when hot) starts first time when cold. waited till near summer to get it tested, got it tested last week was out driving for 30 mins and the temp started going just below the red fan cuts in and the heaters are really really hot. Got it home and swiched the engine off and tried starting it again and wouldnt start (sounded like battery was flat but its a new battery and alternator) so put brand new starter and its still doing it. ive been told the car sounds like its got hydraulic lock when its trying to start and when the engine cools down it starts fine. ive done the thermostat check (feeling how hot the hoses are) both hot. the water pumps ok and the oil not got any sludge in and the cars not losing water, no one seems to know what it is and im a bit sick seeming that ive spent well over £500 for a car ive only drove for half an hour

any help on this will be brilliant, the cars only insured another 2 months!
