The oil pick up pipe is fitted with a mesh over one end this is to

• Prevent large foreign objects being sucked into the oil system

• To strain the oil and keep it clean

• To filter the oil down to one micron

• To increase the oil pressure

The oil pump is fitted with a pressure relief valve what is its job

• Relive pressure in the cooling system

• Relieve pressure in the fuel system

• Relieve pressure in the lubrication system

• Relieve pressure in the induction system

The oil filter cleans the oil and stores debris down too

• 3mm

• 1mm

• 0.5mm

• 1 Micron

• The oils ability to withstand heat

• How long the oil should stay in the engine

1. Tech A states thermostats in automotive engine are used to adjust the temperature of the engine. Tech B states radiators absorb heat from the air to keep the engine warm. Which Tech is correct?

• TECH A

• TECH B

• BOTH TECHS

• NEITHER TECH

The function of a radiator is:

• uses an impeller to force coolant through the engine coolant passages.

• stays closed until operating temperature is reached

• stores coolant

• primary heat exchanger for the vehicle engine

The function of a water pump is:

• uses an impeller to force coolant through the engine coolant passages.

• stays closed until operating temperature is reached

• stores coolant

• primary heat exchanger for the vehicle engine

The function of a thermostat is:

• uses an impeller to force coolant through the engine coolant passages.

• stays closed until operating temperature is reached, then allows coolant flow

• stores coolant

• primary heat exchanger for the vehicle engine

Technician A says that coolant can be a variety of colors with green and orange being common. Technician B says that coolant needs to be mixed with water to provide the best protection against freezing and boiling. Who is correct?
