when i start my 2001 galaxy tdi after about 20 secs i get warning on dash saying stop, a tempreture sign,then message says check coolant...which iv done, a little low topped up warning still there temp gauge climbs to half way 90 deg & stops..watched for couple of days warning still there but no rapid water loss..also now heaters arent as hot as what they where but rad cooling fan working ok as i can hear it when out of car any advice...
OK, my parents have a 2002 '52' ford galaxy 1.9TDI and we have had this problem for quite a while. its usually after you travel over 50MPH the engine heats up and we get the engine heat warning etc. We recently had a service along with cambelt change and when the engine was taken out of the car for that there was oil leaking from the turbo all down the back of the engine which the mechanic says had been like it for at least 3 years. new turbo and she ran like a dream for a few days and started doing it again. We then remembered having a new head gasket around a year ago and he looked at that and found that busseys whom we had to go to for it had NOT flushed out the system (cooling). He did that for us too. and again it was fine for a few days. My father then remembered that the back heater had broken and was causing a thick black smoke as we went along so busseys said it could be disconnected and that would sort the smoking which it did and that is when it started overheated FIRST. So yesterday he spent 8 HOURS re routing the water system in the back heater as busseys had simply blocked it off which was stopping the water flowing around the system and building up pressure and heat!!! He said hed had it running and had run it up and down the road and again it was fine and we shouldnt have any problems. when the car was then parked on the drive i noticed a puddle of water/antifreeze building slowly up underneath the car and my dad checked the fluid when he left for work and it was FULL. He then drove to work and called us later to say it had done it again and was leaking somewhere in the cooling system. today it is back in the garage with what my dad thinks is a header tank. WHAT ELSE COULD IT BE IF IT ISNT THAT?!?!?! We are now at a dead end after that as no-one can find out what is causing it.....has anyone had these sorts of problems too???? Thanks Squishyy

thanks for both your thoughts on the matter had it more or less stripped down today to trace the leak & eventually traced it down to the water pump...and must have only just gone because cam belt was changed 2k ago...is this job do,able or is it a garage job ? your thoughts appreciated...dave...

Hi Rodders, sounds like the engine coolant temp sensor may of failed making the engine ECU think the engine is hotter than it is and putting on the warning light and making the cooling fan cut in making the heater seem cooler, the gauge in the speedo uses a different sensor.
