Well it would seem the old girl has had a slight issue since I have had her

and I put it down to being a diesel and taking ages to warm up, circa 8-9 miles.

but the thermostat hasnt been fully closing for a fair while going by the marks inside

and had then failed fully open on satdee.

So today I had a new one fitted, some nice fresh anti freeze, and they even fixed the seeping from the bleed point

Bang goes this months overtime money
