INTERIM REPORT
I've been getting on with the replacement of the thermostat in bursts of an hour or two each afternoon due to the cold weather.
It's taken me ages, but today I managed to extract (that's the appropriate word !!!) the thermostat. Regrettably it definitely was not stuck open...
This evening I did the traditional "bringing it to the boil" test in the same saucepan as the new thermostat. The old one started to open at 82°C, the new one 88°C.
By 90°C the old one was well open, the new one barely open. At 95°C the old one was wide open, the new one only well open - it didn't fully open until 98°C.
In addition, the old one had a small by-pass hole enabling the passage of some coolant even when fully closed - no such by-pass hole on the new one.
So, ever the optimist, I am hoping that these two factors (opening later and no by-pass hole) will mean that my car will warm up more quickly so I'll no longer be getting P0128 codes and, hope against hope, the car will cease occasionally not restarting when hot.
All thoughts welcome, please.
Meanwhile I'll be attempting to put it all back together over the next few days.
