Can anybody advise before I take my little jazz to a honda garage. My jazz is my first car, so my car knowledge isn't that great. So, My 2009 1.3 automatic CVT 7 speed, Over the past few months I've noticed that my engine coolant reserve levels are dropping really fast, I last had to top it up 6 weeks ago when it was on the min line, I'm now sat just below half way., it's dropped by about a quarter in the last week. There's no visible sign of a leak that I can see. Has anybody else had any issues with this?
