Exhaust Cooling Orifice/Screen Cleaning
The exhaust pipe rubber hoses and muffler are cooled by injecting a small amount of water through an orifice from
the main cooling system into the exhaust stream. The orifice and screen should be inspected and cleaned periodically
to ensure proper cooling of the exhaust muffler and connector hoses. Be sure hoses are not restricted (kinked or
collapsed internally).
Do not enlarge the orifice or a decrease in per
formance will result.
1. Loosen clamp connecting hose to fitting and
remove line.
2. Using a deep well 9/16" socket or flare nut
wrench, remove fitting from exhaust
manifold. Inspect fitting for debris or
restriction and clean if necessary.
3. Inspect and clean orifice and screen.
4. Apply pipe thread sealant to threads of
fitting and re-install. Tighten securely.
5. Re-install air bypass hose and tighten
clamp.
