Make sure all exhaust clamps are in place and secure.
Look for exhaust leaking from exhaust system components. Signs include rust and/or black streaking, water leaks, or corroded or cracked fittings.
Inspect rubber exhaust hoses for burned, cracked, or deteriorated sections. All rubber hoses should be pliable and free of kinks.
Replace exhaust hoses if cracking, charring, or deterioration is found.
Ensure that your engines and generators are properly tuned, and well maintained.
Inspect each water pump impeller and the water pump housing. Replace if worn. Make sure cooling systems are in working condition.
Inspect all metallic exhaust components for cracking, rusting, leaking, or loosening. Make sure they check the cylinder head, exhaust manifold, water injection elbow, and the threaded adapter nipple between the manifold and the elbow.
Clean, inspect, and confirm proper operation of the generator cooling water anti-siphon valve (if equipped).
