My car is a 1972 782 cc car. I have looked in the pretty comprehensive Franzose catalogue, and it shows 7 inline thermostats. There is an 83 deg thermostat for the 782cc car, but no higher temperature type. The 86 deg thermostats are for 745cc , 845cc , 956cc and for the 1108 cc engines, with no mention of the 1126 model or the 782 engine. I am advised on the forum that the 83 deg might be too low for the UK. Can anyone advise please. Thanks as ever.
