Inspection is to include: | checking for coolant leaks in radiator (core and tanks) and radiator hosesvisually check that the coolant level is correctchecking for coolant leaks in water pumps, thermostats (housing) or from hoses associated with the jacket water cooling of air compressors, manifolds, manifold/conditioner adaptor pipes, etcchecking that the hoses are in a good condition, correctly fitted, clamped and restrained checking that the radiator core is clean |
Testing may include: | checking the proper operation and function of the coolant loss detection sensor, and record the time taken to cause the engine to shut downChecking the proper operation and function of the coolant over-temperature sensor, and record the coolant temperature at which the engine shut down. NOTE Testing this sensor by defeating other sensors and overheating the diesel engine system may be hazardous or cause damage to the diesel engine system. It is recommended that the sensor be removed from the engine and tested in heated water while remaining connected to the engine shutdown system. |
