I HAVE done just more than 100,000km trouble-free in my 2001 Toyota Avalon. I noticed in the owner's manual that the cam timing belt should be changed at either 150,000km or after six years, but when I spoke to the service manager at Toyota I was told not to worry about it, as he has never seen a broken belt and there is enough valve clearance to avoid any damage. Does this seem OK?
IT IS unusual a service manager would advise against changing the belt for starters. He's right that there is enough clearance so there is unlikely to be any internal damage, but if it does break you will be left stranded. Car companies are generally conservative when it comes to service on items like the cam timing belt, but I'd err on the side of caution and have it replaced.
