Hey Owain,
Not sure about the BMR, but the Dales ones were actually Fluidyne
radiators.
The Griffin ones were a separate company and IIRC had the glued together
cores.
I hear different things about evans.. one of the things i have heard is
that the coolant runs hotter, but that it doesn't boil, so i guess to ask:
Apart from it registering physically hotter, was it suffering any adverse
effects?
Did it start vaporising the fuel?
Did it start running rough?
Did it puke the coolant?
