Exhaust Manifold - Inspect - Water Cooled Exhaust Manifolds
Normally, water cooled exhaust manifolds do not require maintenance unless excessive deposits build up in the exhaust passages. Buildup of deposits cause an increase in back pressure that will cause the following conditions:
- Increased fuel consumption
- Reduced boost pressure
If excessive deposits build up in the exhaust passages, clean the passages in order to remove the deposits.
In landfill applications, the composition of the gas can corrode engine components such as the water cooled manifold. Inspect the manifold. Repair the manifold or replace the manifold if any of the following conditions occur:
- Cracks in welds
- Cracks in the base material
- Coolant leaks
- Exhaust leaks
