These little guys basically provide a sealing surface between the exhaust flange and the exhaust manifold or pipe. They help distribute the clamping force from the nut or bolt evenly, creating a tight seal. Sometimes they act like a shield, protecting the threads from heat and corrosion too. You’ll find them used with exhaust manifold gaskets, downpipe connections, and anywhere exhaust components bolt together. Think of your exhaust system as needing to be completely sealed to keep all those nasty gases contained and directed away from you and the engine. These washers are a small but crucial part of that sealing process. Without a good seal, you’ll have exhaust leaks. They’re positioned between the bolt head or nut and the exhaust component itself to ensure a solid connection. Exhaust leaks aren’t something you want to mess with. They can sound really annoying, of course, but more importantly, they can reduce your engine’s performance. Leaks throw off the oxygen sensors, messing with your fuel economy. Also, exhaust gases are, well, toxic. You don’t want those fumes getting into the cabin of your vehicle. Over time, a corroded or missing washer can cause bolts to loosen and even break. You’ll notice if you have an exhaust leak because you’ll usually hear it – a ticking or puffing sound, especially when the engine is cold. We carry a pretty good selection of these at Fixparts Online, and getting the right size and material is key. Usually copper or aluminum are the most common, but it depends on the application.
