Стр.22 упр.2- прочитать инструкцию по самостоятельному ремонту системы охлаждения, ответить на вопросы теста, согласно информации в инструкции:

       Any driver can keep a cars cooling system healthy. Professionals only need to be consulted when something has to be replaced or fixed.

First, the easiest way to maintain your engines cooling system is to keep adequate antifreeze levels.

Also known as coolant, antifreeze works to keep the fluid in the cooling system from boiling or freezing. A coolant recovery system provides a reservoir for the radiator. It collects overflowing coolant that can be returned to the radiator after cooling.

Next, check the radiator. The upper radiator hose should be delivering liquid to the radiator, and the lower radiator hose should be releasing liquid from the radiator by the force of the water pump.

A serpentine belt and pulleys may power the water pump, so inspect these pieces carefully.

Also, make sure the heater hoses are connected to the heater core and that the thermostat is operating.

Finally, the fan should be pulling cool air through the radiator fins while the car is idling.

Практическое занятие №46 «Рулевое управление»

Стр.26 упр.2 — прочитать отрывок главы, посвященной устройству рулевого управления опровергнуть или подтвердить высказывания, согласно информации отрывка:

Rack and pinion steering is one of the most common steering systems used today. But few people actually know how it works. It all starts with the steering wheel. It turns a steering shaft, which is attached to the pinion.

The pinion, a gear locks with the rack, another gear. So when you rotate the wheel, the steering shaft turns the rack.

Attached to each side of the rack are inner and outer tie rods. These rods connect to the spindles. As the rack pulls and pushes the rods, they move the spindles. And it is the spindles that hold the wheels. By turning the spindle, the rods turn the wheel.

Most modern cars also have power steering. In these systems, the rack has a cylinder with a piston in the middle. The power steering pump supplies high pressure fluid to move the piston. This reduces the amount of force needed to turn the pinion gear and rack.

1 – The tie rods connect to the control arms and pinion.

2 – The tie rods turn the spindles.

3 – Power steering removes gears from a steering system.

Практическое занятие №48: «Система трансмиссии : дифференциал и основные соединения»

Стр.30 упр.2 — прочитать колонку совета для автомобилистов, согласиться или опровергнуть высказывание

. It sounds like you have a problem with your joints, which transmit the rotary motion of
transaxle to the wheels. If you have a rear-wheel  drive vehicle, you likely have U-joints.
A U-joint is essentially two connected hinges. When the connection is loose, they spin and make a
“clunk” upon meeting. On the other hand, if you have a front-wheel drive car, you probably have    CV joints. Like U-joints, CV joints produce a knocking sound when loose. However, the problem usually begins with the CV boot. A cracked CV boot lets grease escape and dirt enter. The result is
that the coupling experiences too much friction, wears-down, and loosens. But no matter what joints you have, you need to get to a mechanics before the joints completely fail and you lose control of your vehicle.
 .  1   What is the purpose of the passage?
      A  to show the steps of joint replacement
      B  to recommend switching to CV joints
      C  to explain symptoms of U and CV joint damage
      D  to describe the difference between U and CV joints

      2   Where does damage to s CV joint usually start?
   A  a worm down hinge
   B  a cracked CV boot
   C  a loose coupling
   D  a snapped transaxle
   

3. What is probably true of a car with a damaged CV boot?
   A  It needs a new U-joint
   B  It has front-wheel drive
   C  It cannot transmit rotary motion
   D  Its CV joint has completely failed
