simonpelly Posted March 30, 2021 Share Posted March 30, 2021 Hi Folks, Need to remove the viscous fan from our 300 Tdi. I have an order outstanding with Bearmach, BA4912, which keeps being extended out (now 6 weeks) - Perhaps it's somewhere in a container in the Suez canal 🙂 In any case, would be interested to know what other tool options are. Not clear to me yet what is entirely involved. Thanks, Simon... Quote Link to comment Share on other sites More sharing options...
simonpelly Posted March 30, 2021 Author Share Posted March 30, 2021 Think I've answered my own question with more web searching - 32mm thin profile spanner, left hand threaded nut? Simon... Quote Link to comment Share on other sites More sharing options...
monkie Posted March 30, 2021 Share Posted March 30, 2021 I have something like this. I can't remember exactly, but yes I think it maywell be left handed thread - you'll soon find out! Quote Link to comment Share on other sites More sharing options...
simonb Posted March 30, 2021 Share Posted March 30, 2021 Yes LH thread, - in other words it undoes the "wrong" way. Strike the end of the spanner with a hammer, which should shock the nut undone. Refit just finger tight otherwise you will never get it off again. Quote Link to comment Share on other sites More sharing options...

Northwards Posted March 30, 2021 Share Posted March 30, 2021 I bought one of these purpose-built viscous coupling spanners, and the jaw bent open first time I tried to use it. They are pretty thin, but maybe that one was especially cr@p. For whatever reason, I couldn't wait for a replacement so I just took a grinder to a 32mm spanner I had and made it into a 'thinner profile' one. It gets in there Ok and does the job fine, and I don't think its strength has been significantly affected. Maybe another option depending on circumstances, and what you have to hand.
