Tis I. I didn't realise your 740 was a TD

Thinking more about that, lack of that blocking disk would worsen an overheat situation more than underheat.
RE: correct orientation, that disc should be facing into the head, with the peaked part of the tstat facing outwards. Then the rubber seal (hope you did install that?) is sandwiched between the tstat and the bolt-on flange, as shown in this dwg. |
Thank you - I am pretty sure I've installed it correctly. I wouldn't be certain that I fitted the O ring on the correct side - I will pull the 'stat out again, test it, and re-fit ensuring everything is correct.
Thanks
