Hello, I have a R75 diesel auto with the usual lack of heat from the heater. A couple of years ago I fitted the recommended in-line 89 degree thermostat in the top hose and although it has improved, in winter it is still not what you would call warm.

Today I set the dash display to show temperature and took it on a run including a motorway. The highest reading was 84 degrees. Should it be higher? Is it worth trying a different 'stat or is that as hot as it should get?

I've done all I can to eek out as much heat as possible, with a new matrix, ensuring no kinks in the hoses and shrouding the hose that passes in front of the engine. Is there anything more I can do?

Many Thanks
Steve
