Hi all I am new to the world of being a citroen C3 owner and i have a few issues that i cant seem to sort and have left me completely confused. I have a C3 desire 1.4 on an 05 plate and would be grateful for any advice. Firstly the engine temp seems to erratic according to the dash display. after 6 miles of driving it gets to the first bar only. after i have travelled 8 miles to work it still sits on the first bar, however if i turn the engine off then turn the ignition back on it shows 2 bars. i have taken it on a 200 mile motorway journey and it goes up to 3 bars and drops between 3 and 1 bar and vice versa even when travelling at 70mph. Secondly which is the most worrying is that the heater will not blow warm air, it will blow cold and mildly warm even when the dash states 3 bars, the water level is on the max on cold and after a journey it goes down halfway between max and min. i leave the car parked for 24 hours and open the expansion tank and pressure releases and the level comes back to max or sometimes a little below max. I have had the water pump changed by my local garage who i have used for years and never had a problem with, but it still does it. is it normal for it to hold pressure even when cold for 24 hours? it has been bled several times and the pips going to and from the heater are warm but the air is still cold. Are these faults connected in any way and how can i fix them as my garage is baffled and i have no ideas. the thermostat looks new so i have not had it changed yet. there is no oil in the water or water in the oil and no obvious signs of a water leak i have ordered a haynes manual but can anyone tell me what i need to do or change as i am all out of ideas. Engine has done 96,000. the cambelt looks good for another 30,000. do i need a new engine or just to change some parts if so could someone tell me what parts and where they are as i am not that mechanically minded. The car other than that is really good, i am 6ft 3inches and fit in it great and lots of space etc i just dont want to destroy it by not doing the fixes. thanks in advance alan
