Hi Colin, Thanks for that, it looks like it's the thermostat which is a big relief. Cheers, Les.

The heater on my ZX has just stopped blowing hot air. I have seen the prevous posts regarding heater matrix failure but I have no leaks in the cockpit or engine comparment. Also, the cooling system is overheating very quickly which I have not seen mentioned on the other posts. Am I looking at a new matrix and all that involves or is there a blockage in the system? If the latter, advice on shifting it would be gratefully received.
