I'll have a look when I get it back, hopefully this week. They tested the fan and it worked. I had to top up the header tank on way home with a couple of litres of water when the temp rocketed to about 150 which brought the temp down and also had a good effect on oil pressure, but about 5 miles later as I pulled into my street, the thermos housing cracked and water went everywhere. So for the cost of an £8 radiator cap, it's ended up costing about £500 😭
