Checked the anti-freeze I put in a couple of weeks and realised I stuck in OAT stuff in error. Flushed the system a few times and then had a closer look at the radiator.
A few years ago it had a rebuild by a 'non-morgan' restorer, and there are aspects where I think he didn't have a clue. As a result, the radiator was raked back, so the top of the radiator was much higher than the filler cap. The triangular top mount was bent down at a 45 degree angle. So straightened the mount, unbolted and swivelled the mount bar, and refitted. The top of the radiator now gets warm!
I think that will help get rid of any airlocks in the system and hopefully get it much warmer. I imagine if I'd been running in the summer, I may have had some overheating issues.....
(and what a joy to get home in the daylight, and be able to do an hour or so of work before it gets too dark outside)
