Hi, I have a 97 grand caravan 3.3 with only 43,000 miles and not even close to the replacement miles for the belt which just fried because the single bolt for the tensiner just broke on start up with a big squeal and then a pop and then a bunch of smoke with out warning and could leave you stranded anywhere on the highways or in the country.I open the hood and the tensioner was just laying there and the broken bolt was on the ground. Had the van towed to the dealer for repairs because my 7/70 warranty is still good and will take care of the tensioner but not the belt or the tow. the manual says check at 50,000 mi and then replace at 70,000 mi if not changed at 50,000 mi. Very funny that the van only has 43000 mi. on it and goes even before the belt is soposed to be checked for wear. tensioner on these vans go before the scheduled replacement of the first belt because of a bad design and a weak bolt! Asked dealer if the bolts have been upgraded and he said no they are the same. Seem like manufactures should learn from there mistakes! any one had these same kind of experiences with these poor designs and know if there is any recalls yet. thanks for any info!
