finally got around to fitting 2 10'' thermos in the front of the defender.
dont know if it will make a difference to the A/C system but it has to be better than one...
the OE fan is a around 11''dia, so 2 of them will not fit. but as good fortune would have it i ''happened'' to have a few 10'' jobbies ''floating'' around they fit perfect!

cheers phil
