Phil,
It seems that you have the same coolingfan setup as a Deauville.
Last month I replaced my 2 thermoswitches for the coolingfans since the old ones were bypassed by the previous owner.
The top one I replaced with a Facet # 75004, 67-70 degr. celsius. This one is for the primary fan. The bottom one I replaced with a Facet # 75018, 80-85 degr. celsius for the secondary fan.
After this simple and cheap, about € 30 for the 2, it now cools as it should!
They are nothing special and off the shelf since they are used in also in several Peugeot, citroen and VW cars.
