On an old 2007 Hyundai Accent I have my granddaughter using she ran over a clump of grass that was hiding a rock, and ripped out most of the exhaust pipes. I got two pipes, 2nd cat converter (missing in action) and muffler, then went to my favourite mechanic to have him remove the seized flange bolts that held the front half of the first pipe to the outlet of the combo exhaust manifold/1st cat converter. He found that units' outlet flange had broken off, and the stub of pipe left was 'way too short to try to weld a new one back on. So now I'm waiting for delivery of a new one of those combos, plus the 2nd Oxygen sensor to fit into the first pipe. Replacing literally the entire exhaust system.
Meanwhile my granddaughter was using my 2014 Mazda 3 and it stranded her with multi warning messages, starting with major failure of charging system, pull over and do not drive. With a little thinking I realized the serpentine drive belt had broken off. So I drove over in her noisy car to "rescue". My wife and I drove next day to the stranded Mazda with new belt and tools. But the belt tensioner unit you have to move with a 17mm wrench is in such a bad location you cannot get a socket onto it. I drove around to several stores looking for just the right tool, had to settle for a common 17mm combination wrench. Turned out the tensioner was not too hard to turn with that plus a rod to push it in a tight space. Many wriggles of the belt in tight quarters got it in place and the tensioner released. All good! Now I'm thinking that the related belt that drives the water pump probably is just as weak! To replace that I'll have to remove and re-install that same serpentine belt!
