What antifreeze should I put into this thing? AIUI, they're somewhat fussy (the 2.5l aluminium straight-6) and the earlier 3l had an infamously poor reputation for block leak problems, whether caused by poor castings or by incorrect antifreeze.
Unipart have just given me the "They're all the same, guv" response. They also offered an OAT, which could have been made from oatmal for all the advice the guy in the shop could offer.
I'm loathe to go and buy Volvo's magic fluid, because I doubt very much if it's any better than many other equally comparable products -- but how to tell ? Is there any standard quality rating system for antifreeze? What is the Volvo stuff anyway, just a corrosion inhibited ethylene glycol with a low phosphate content?
Even my Bosch handbook seems quiet on antifreeze grading. Is a more recent edition (6th or 7th) any more informative?
Thanks for any advice
