i was down in cornwall late last week getting my tm serviced and with the weather in mind and due to the fact that i was staying until sunday, hm filled the system with anti-freeze for me. i admit i was doubtful as the forecast was COLD, set off for home on sunday morning and it was minus 7 and the van had been in an open carpark next to the sea! got back yesterday afternoon and drained the anti-freeze and put the heater and fan in for the night and kept fingers crossed.
today, all ok, phew!
