hi all, i have a octavia estate 1.9td glx which started overheating on the hill of the motorway.

my local garage have had this for 9 days, and are still sruggling, could it be water pump? or they said thermostat, but they cannot get the cover off it, they say engine write off if bolts break off

is this true? i am worried by this. another garage seem confident that the impellor is the cause, as it needs a cam belt no big hardship if so.

please help cheers paul.

Water pump failures are pretty common, more so on the 1.8 lump than the diesel. Therefore if the car is not far away from a cambelt change, then consider doing a belt change, along with new water pump, pulleys and tensioner.

Agreed.

Not familiar with the thermostat location on the TDI engine but on the 1.8T petrol the plastic cover tube over the top of the thermostat bolts into the front of the block so if there is an issue with the bolts the whole engine would need to come out and the bolts be drilled and re-tapped if possible.

hi paul, my brother has a vw bora 1.9 tdi pd130 and he had been suffering with the same problem, his car was fine until he booted it and then it would overheat and spit out water from the expansion tank. anyway he booked it in to vw technica in chelmsford for a cambelt / water pump change. on the way home from picking it up he gave it some whelie to test it out and the same thing happened? he phoned the guy up immediatly and was told that it must be the thermostat not opening then?, but my brother had recently tried replacing that? anyway to cut a long story short, it turned out that my brother had fit a non original thermostat that was not working :(

apparently the guy at vw technica told him that he used to use patterned parts and had nothing but problemswith them, so now only fits oe parts.

my brother changed the thermostat for an oe one the next day (last week) and has had no problems since.

the point of this is if he had only of fit an oe thermostat he would have saved £300 pound that it cost him for the cambelt / pump change. :(

so i would try the thermostat first. i cant see why they are having a problem removing the housing as its only two 10mm bolts?

anyway good luck and keep us all updated.

regards

nick

Hi GUYS thanks for the posts re my skoda overheating- called at the garage today and found rather smugly that i was right all along water pump impellor completely off its shaft.

new pump and cambelt and all should be fine no need to touch thermostat bolts now!
