[928uk] Overheating

[Max via 928uk]

Well, looks like a survey coming up...

My gauge reads 2/3 and gets there fairly quickly.
The system was checked out fairly recently by Mr.PA, so I expect that 
it's normal.

Interesting, my GT reads just over as well, about 2/3. I was a little
worried too,however the previous owner replaced the thermostat and
must have acknowledged that its nothing to be concerned about. Is he
right I wonder?
