spadam 7 Posted March 5, 2009 Report Share Posted March 5, 2009 Im losing coolant slowly i recently changed the expansion tank cap and refilled thinking it was a faulty cap. Anyway around 2 weeks later doing around 50miles a day i checked again and my collant was very low. I have no mayo in dipstick or on cap and no oil in water. i cant see any definate leaks but i did notice pink coolant round the back of the expansion tank where the black cover sits with to holes underneath. looks like it may have come from those holes. would could cause this and how do i fix it. the cars an obd2 80,000 miles and 1998 registered if thats any help. any help much appreciated Link to post Share on other sites

thegoth 5 Posted March 5, 2009 Report Share Posted March 5, 2009 those are the pressure release holes which should be controlled by the cap. I'd have a good clean around and top her up to make sure they aren't old stains Link to post Share on other sites

spadam 7 Posted March 5, 2009 Author Report Share Posted March 5, 2009 not changed the bottle yet only the cap. I cleaned the bottle when i put new cap on so they are fresh stains. Do the bottles fail then if so looks like il buy myself a new one. Do gsf sell them Link to post Share on other sites
