M.Hawkins92 Posted June 8, 2012 Report Share Posted June 8, 2012 So, last weekend my lupo decided to overheat to erratic amounts which included me burning my thumb!1) i drained and flushed the sysem2) replaced stat3)when driving it will sit on 90 until you give it some it decides to rise towards the 110 mark, but i put the heaters on full whack it goes back to 90?!?!so im puzzled..is it the waterpump? Stat sensor? Huge air lock? Headgasket?Thanks for any comments and feedback as im missing the lupo as its sat on my drive now Quote Link to comment Share on other sites More sharing options...
FatelError89 Posted June 8, 2012 Report Share Posted June 8, 2012 the temp will drop when you open the heaters on hot as its taking heat away from the coolant when you changed the stat did you leave the heaters with on hot with the fans open when filling it back up with coolant if you dident that would cause air lock also when you took the stat out was it stuck closed ? also on the coolant tank can you see the water circulating ?
