timing belt or chain - 2/19/2007 5:08:27 PM    woodsballr   Posts: 211 Joined: 1/6/2007 Status: offline as you can see i have a 91 s10 blazer. i was reading thru Popular Mechanics and they had a DIY thing on replacing timing belts. well that got me to thinking and i said "self, i don't remember the timing belt having been changed since we've had it. that could be worth looking into." and then i said "self do i have a timing belt or timing chain?" and then i said "self i am hungry." okay my question is do i have a timing belt or chain. whoda thunkit? and also when should it be changed as i have almost 210K miles on my blazer? thanks _____________________________ 1985 GMC High Sierra 1500 w/a 5.7L V8 + a 4-barrel carb. ~~"Live like you ain't afraid to die"~~the late, great Chris LeDoux Post #: 1

Basically, don't worry about it until it happens, lol _____________________________ (in reply to swartlkk) Post #: 4
