A donut gasket is ofttimes used to seal a vehicle's front exhaust main and manifold connexion. On the other hand, there can be donut gaskets used in other locations downstream in the exhaust development of trustworthy vehicles. The shape of the gasket resembles a donut and it seals the exhaust pipe that has a ball flared head.
Instructions
1. Lift the vehicle all the conduct up on the vehivle lift.
2. Situate on the safety glasses and collect all the tools you obligation and accommodation them in a handy aim near you under the vehicle.
3. Arbitrate provided the front exhaust conduit is a Y-pipe. This would scrimpy that it attaches to the engine at dual manifold locations on both the left and fly side, then downstreams into a unmarried Hospital ward channel. Provided this is the event, you Testament demand to remove both front flange-to-manifold connections. Provided it is onliest a single-chambered main, you Testament alone commitment to remove the unmarried flange-to-manifold connexion.
4. Set up the ratchet, extension and appropriate sized socket for the nuts on the manifold studs and make sure the ratchet is set in the reverse position.
5. Light the torch, choose one manifold stud nut to heat and heat it to a cherry red color.8. Allow the pipe and manifold to cool down some. Remove the old gasket and insert the new one.
Remove all the nuts from the manifold studs using this procedure. Take your time and be careful not to break any studs.
7. Put on the safety gloves and back the front pipe away from the manifold. Use the pry bar for leverage to help. In order to accomplish this, you may have to remove some of the hangers downstream on the exhaust system To admit some movement and flexibility.
Quickly shut off the torch and apply the ratchet, extension, and socket to the nut and back it off the stud. If you feel any resistance, relight the torch and re-heat the nut some more so you do not break the stud.6.
9. Rethread or chase the manifold studs (once you've allowed them to cool) To cleanse the threads on them before replacing new nuts onto the studs.
10. Replace the nuts and tighten with the ratchet, extension, and socket.
