Important Things to Know About Landfill Gas. Important Things to Know About Landfill Gas is available in Portable Document Format (PDF, 160KB, 2 pg.) Summary. Landfills can produce objectionable odors and landfill gas can move through soil and collect in nearby buildings. Of the gases produced in landfills, ammonia, sulfides, methane, and carbon dioxide are of most concern. Ammonia and hydrogen sulfide are responsible for most of the odors at landfills.
With the ignition on and the engine not running, disconnect the gauge wire (yellow with red stripe) from the sending unit in the coolant outlet on the cylinder head. On 16-valve engines, the sending unit is on the driver's-side end of the cylinder head. Ground the wire. This simulates a high engine temperature signal to the gauge. If the gauge needle moves upward, the sending unit is faulty and should be replaced. If the needle still does not move, either the wire to the gauge is broken (open circuit) or the gauge is faulty.
How to Check Your System. 1  The first thing to do is to check the engine mounts. 2  Conduct a back down test. 3  Observe the shafts while running at two speeds, idle and cruise.  Many boat yards think that the way to check shaft alignment is to disconnect the coupling and check the flange clearance with a feeler gauge. That's only part of the story. Before doing this, with the vessel hauled, check the position of the shafts relative to the bearings.
