Citroën BX - Thermostat replacement & End

The thermostat was still the original one, from 1984 - no wonder it had finally seized and led to overheating. Thankfully, replacing it is a simple job and it seems no harm as been done - I got out of the motorway as soon as I heard the coolant spraying in the engine bay.
After this, the car has successfully gone for a MOT and it's been sold. I'm already missing it!
