At a local UK toyota dealer ,the manual recommends timing belt replacement for my 3litre Alphard every 80 to 100 thousand miles. The mechanic said they are made so well they easily last 200 thousand miles. (They wont touch imports) In America when tested on a bench the 3 litre engine was found to be " safe", with the valves not hitting the pistons if the belt snaps. (Toyota states incorrectly ,not a safe engine !!!) Even so is there anyone out there in the UK who can change my belt on a 2005 model ? Looks a fiddly job. Im in South Wales.
