All Power America Exhaust Leak

Generator runs but there is a loud hissing sound and possible exhaust leak near the engine.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Cracked exhaust manifold, Loose exhaust flange bolts, Damaged exhaust gasket, Rusted muffler

Safety first: Shut down the generator and allow the exhaust system to cool completely before touching any components.

Inspect exhaust joints: Check the manifold-to-head and manifold-to-muffler connections for soot marks indicating leaks. Tighten bolts evenly.
Replace gaskets: If gaskets are burned or missing, replace with OEM exhaust gaskets for your All Power America model.
Check muffler: Inspect the muffler for rust holes or cracks. Replace the muffler if damaged.
