The radiator is responsible for tranferring heat from the coolant to:
outside air |
|
thermostat |
|
engine block |
|
cylinder heads |
The radiator is responsible for tranferring heat from the coolant to the outside air. Radiator hoses transfer coolant to and from the engine to the radiator and a radiator cap maintains pressure in the cooling system to increase the boiling point of the coolant mixture and thus allow it to absorb more heat.
Control arms connect a vehicle's suspension to the frame. The connection to the frame uses:
bushings |
|
knuckles |
|
pins |
|
ball joints |
Control arms (upper and lower) connect a vehicle's suspension to the frame. The connection to the wheels is through ball joints which allow the control arms to turn and move up and down simultaneously. The frame connection uses bushings.
Which of the following transfers the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension?
constant velocity (CV) joint |
|
transfer case |
|
springs |
|
control arms |
Constant velocity (CV) joints are located at both ends of a half shaft and their purpose is to transfer the torque from the transmission to the drive wheels at a constant speed while accomodating the up and down movement of the suspension. The inner CV joint connects the shaft to the transmission and the outer CV joint connects the shaft to the wheel.
The primary purpose of the muffler is to:
quiet exhaust |
|
remove harmful gases from the exhaust |
|
reclaim unburned fuel |
|
cool the exhaust |
The muffler follows the catalytic converter and absorbs sound to help quiet load exhaust. It is followed by the exhaust pipe which is the final exit point for exhaust gas from the vehicle.
Which of the following is not a function of a car battery?
delivers supplemental current when the alternator can't handle high electrical system loads |
|
acts as an electrical reservoir for excessive current |
|
delivers current to the ignition system to start the engine |
|
acts as a supplemental source of energy to moderate engine performance |
The lead-acid battery is the core of the electrical system, providing current to the ignition system to start the engine as well as delivering supplemental current when the alternator can't handle high electrical system loads and acting as an electrical reservoir for excessive current.
