I changed the coolant today but after removing the lower rad hose and undoing the bleed bolt on the rad I only needed about 6 litres to refill, book says 11-12 litres, what is going on? cheers, John.
Hi Andy, yes, header tank empty; I had it nose down in the driveway and thought I'd pretty-much emptied it, maybe it's worth just doing a drain-down like last time and another 6 litres; this must be close to changing the lot.
Thanks for all the advice from Dave, Dave and Dave. [Is this a coincidence and probably worth buying a lottery ticket?] Hope things work out in Germany Dave, call me when you get back, cheers, John.
