On this one the power steering is right up on the top of the engine. Alternator belt tensioner is the one on the bottom. It has 70,000 miles on it. I figure the Timing Belt does maybe need to be replaced, but I don't have the Bucks for that right now. I know if it happens to break it is gonna cost a WHOLE LOT MORE. I plan on having it done the first of the year after Christmas. And although I completely rebuilt the 302 in my old ford I don't think i want to undertake the timing belt job myself! I am just replacing these because the guy at Goodyear when they put the tires on there pointed out to my wife that the belts were cracked and with us fixing to have to go on a trip my wife wanted them replaced. So I told her I can do that myself. Thanks for the warning about the bottom tensioner.
