What are the part numbers for the highlighted sections of exhaust heat shield? They've started to get worn out and fall down.
Parts.Toyota USED to be a good resource; been hooped since a revision a few months back. Some of it here? Are you near a dealership? Ask the parts guy? That’s their bread-and-butter. All that said, is it just fasteners missing, or the holes torn out? Fender washers (purchased or cobbled from some sort of sheet metal), and new fasteners as needed, may be all it takes.
Let them go you'll never even notice that they're missing other than the absence of the noise. Your floors get hot in the Prius regardless they do in my Corollas too He shields in place or not The temperature of the floor is the same It's been that way since the cars were cleared for production or what have you so the heat shields not really doing anything for you. But if you're willing to buy by all means purchase heat shields from Toyota. Like Mendel said usually fender washers and a bolt or two will clamp them back up and make them quiet some of them in some other vehicles aren't even metal anymore they're like aluminum foil and chicken wire squished together and they use these bolts with little fender washers if you will to hold them in place and then the chicken wire fails and they fall right off of the little washers built to the bolts and then eventually slide around the pipe and fall on the ground I just got rid of several of these on a couple Suzuki cars. Given the fact that I'm in the southeast United States by the time these fail rattle and fall off here the car is been ready for the junkyard generally speaking but as long as I keep cars some of these things are removed rather than replaced.
