Our Golf Mk2 GTD is back for it's yearly round of cooling problems. It's been good as gold for over a year but seems to have saved everything up to go wrong together... It's acting very weird, seems to heat up quicker than it should and gets to about 75% on the dial before slowly moving back and forth between 50 and 75%. Does seem to be getting worse and is now creeping over 75%. Garage don't know what is up with it, think it could possibly be a split in the turbo letting air in. It's had a new head, rad, expansion tank and cap and thermostat all within the last year or so. Interestingly I thought it could be the thermo again (as it was building up pressure when revved on the drive then it would dump a ton of coolant out of the expansion tank before the fan would come on briefly) however when I changed to a brand new thermostat the problem actually became worse. Any ideas? Garage has done a sniffer test and there's no signs of gases in it. Also no pressure still in system when its cooled down. Struggling to know what to do with this one!
