I was thinking the same.
Interesting your thoughts on the fracturing.
AFAIK its not an issue in Defenders, as they are pin mounted top and bottom in rubber bushes so float.
I bought an OEM one, Glasgow Radiators, I think, from Roverlord. This was in January, I'll let you know what it's like when I fit it[biggrin]
All good advice, but I feel no wiser. [ I was a bit like that at school, too.[smilebigeye]] My concern with the D2 radiator is the plastic sides. That's where my first one leaked, just ever so slightly. I just recalled that MR Auto bought in a few fully welded aluminium ones from China. They were going to do a trial on them, but I didn't bother to find out if they were any good. I still have this anti-China bias, probably wrongly. Might just check up on them. Don't sell yourself short Tombie. Leave that up to the dibbies.
