Statistically speaking, the Renault 5 type in-hose thermostats perform better than the 'most' standard diesel ones. Of these alternatives the ones branded FirstLine, Wahler and Gates are the best performers. They are known to be watertight when shut, which is important for diesels. You should try to get one with a nominal setting as close to 90C as possible. There are 89C ones available if you search. The 86C one you link to wouldn't be my recommendation.
