forsh21 Posted March 14, 2013 Report Share Posted March 14, 2013 Hi,My lupo GTi seems to be using alot of water, its not leaking anywhere and the temperture gauge seems ok never goes over 90, and the heaters work fine. At first i fort the head gasket but its using it that fast i fort it could be down to the expansion tank????? ive checked the oil and theirs no water in there. Anybody ever had this problem before?cheers Quote Link to comment Share on other sites More sharing options...
forsh21 Posted March 14, 2013 Author Report Share Posted March 14, 2013 If the expansion tank was on its way out what problems would this cause?????? Quote Link to comment Share on other sites More sharing options...
lupogtiboy Posted March 14, 2013 Report Share Posted March 14, 2013 Mine had a hairline crack on the thermostat housing which was replaced when I had the engine rebuilt. Expensive though at £98.05 inc vat from VW!!! Quote Link to comment Share on other sites More sharing options...
FatelError89 Posted March 14, 2013 Report Share Posted March 14, 2013 Pressure check it and mite show where it is leaking from. yeah those thermostat housing are stupid price lucky enough to get mine £55.00 from vw Quote Link to comment Share on other sites More sharing options...
forsh21 Posted March 14, 2013 Author Report Share Posted March 14, 2013 Pressure test first then I think, if the expansion tank wasn't holding presure would the car still get up to normal running temperature??? Quote Link to comment Share on other sites More sharing options...
Pete Posted March 14, 2013 Report Share Posted March 14, 2013 Yes, surely if you're using that much coolant a leak would be fairly obvious? Quote Link to comment Share on other sites More sharing options...
FatelError89 Posted March 14, 2013 Report Share Posted March 14, 2013 yeah if your losing that much it would show from some where. you getting white smoke from the exhaust ? Quote Link to comment Share on other sites More sharing options...
forsh21 Posted March 15, 2013 Author Report Share Posted March 15, 2013 there's a bit of white smoke on start up, but i fort that was normal on the GTi's Quote Link to comment Share on other sites More sharing options...
