- While diagnosing an engine that overheats after frequent hard accelerations: Technician A checks for a collapsed lower radiator hose. Technician B checks the cooling fan electrical circuit. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardTrue or False? To eliminate the drain of engine power during times when cooling fan operation is not needed, many of todays belt-driven fans have a fan clutch that prevents the operation of the fan when the engine and radiator are heated up.arrow_forwardWhich of the following statement is correct according to the Wind Energy Conversion System? O a. Low speed high torque shaft is connected to wind turbine, high speed low torque shaft is connected to generator O b. Low speed high torque shaft is connected to generator, high speed low torque shaft is connected to wind turbine O c. Low speed high torgue shaft is connected to wind turbine, high torque low speed shaft is connected to generator O d.

- Technician A says that black exhaust smoke is an indication of a too-rich air-fuel mixture. Technician B says that white smoke (steam) is an indication of coolant being burned in the engine.arrow_forwardTechnician A says that you may be able to smell antifreeze from a leaking heater core. Technician B says that you may be able to hear a loose belt when the engine is running. Who is correct? Select one: a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardA vehicle has had several radiator replacements, and each time there has been pinhole leaks in the aluminum. Technician A states that the engine coolant may need to be exchanged more often. Technician B states that the engine grounds should be inspected closely since this could be the cause. Who is correct? Select one: a. Technician A only b. Technician B only c. Both Technicians A and B d. Neither Technician A nor Barrow_forward
- The diesel engines operates with low pressure than petrol engine a. FALSE b. TRUEarrow_forwardTechnician A says that liquid cooling an engine helps to maintain a consistent operating temperature. Technician B says that oil is circulated through the cooling system to remove heat from the engine's parts. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardWhich of the following is not a true statement about thermostats? Faulty thermostats are often the cause of air pockets in the coolant passages. They can also cause an increase in fuel consumption and poor engine performance. If the thermostat is stuck open, the coolant may not reach the desired temperature because it is cooled before it gets hot If a thermostat is stuck closed, coolant will not flow between the engine and radiator and the engine will quickly overheatarrow_forward
