So I've been researching the timing belt for my new 99 Runner, and have decided to do it myself. My 4runner has 125000 miles, and no maintenance records, so I figured it needed it. However, looking under the hood today I see a sticker that says a Gates timing belt was installed at "blank" miles, at "blank" location. Nobody bothered to fill It out. Does this mean it was done, or is this sticker here for when it is done? Seriously, how hard is it to pull back the cover so I can see the belt to inspect it, cause I'm not sure what to think here?
