Another dentist's appointment on Friday, so back out to Mum and Dad's place again. On saturday, when I'm supposed to be recuperating, we get the genius idea of swapping out the radiator on Dad's sprinter so I can have his old one while I get mine looked at.
It didn't take that long to swap everything out, but we stopped for a coffee break half way through. After that, just before lunch time, we filled it up with coolant mix and idled it for a bit to bleed and check for leaks.
Then we took it for a spin the Talbot block and the temperature stayed perfectly flat - I'm very impressed.
I wish I'd made enough money this year to warrant just buying a brand new radiator already.
