Talk Morgan Forums Thread Like Summary - Viscous coupling

Hi, does anybody know what the part number is of the viscous coupling on a 1980 4/4 with a 1600 x-flow? Or what else it may have been used on?
Thanks
Neil

The fan is fitted in front. The original fan was removed when the alu radiator was fitted about 15 years ago. I don't really know how often the fan comes on, but afaik there have been no cooling problems.
