Since last proper update, it has had its new box fitted (thanks Laidback66, JamesV6CDX, Tunnie, and Ronnie McB for various help
).
I have not yet had the head off (working up the courage!).
However, this is where the plot thickens.......
I have just taking it out, and ragged the chuff off it for 20 odd miles. Villages aside, my foot was hard on the floor, either on accelerator or brake.
Yet I couldn't get the temp to go above 97 on gauge :-/
Before, if I had done that, it would be way up the gauge after 2 or 3 miles. OK, the temperature is down a couple of degrees (currently 18C), and the A/C isn't working - could the condensor be creating too much heat? :-/
Bizarre...
