I posted a while back about my coolant warning light coming on, the level does seem to be dropping over a period of weeks/miles. I can't see any lose hoses etc. I was thinking of running some of that stop leak addittive through the system. Anyone got any ideas what the problem might be ? Its not a major leak. The level in the top up tank goes down by about 2 inches max and the warning light flickers when its cold.
The car is a peugeot 306 D Turbo 1997
Thanks In advance
