What is the function of the head gasket?
to seal the engine block from the cylinders |
|
to seal the brake assembly from external contaminants |
|
to connect the transmission to the drive train |
|
to seal the exhaust system from the drive train |
A head gasket is a gasket that sits between the engine block and cylinder heads to seal the cylinders to ensure maximum compression and avoid leakage of coolant or engine oil into the cylinders.
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?
springs |
|
control arms |
|
constant velocity (CV) joint |
|
transfer case |
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.
Which of the following is not a function of a car battery?
delivers current to the ignition system to start the engine |
|
acts as an electrical reservoir for excessive current |
|
delivers supplemental current when the alternator can't handle high electrical system loads |
|
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.
Which of the following regulates the flow of coolant through the radiator?
water pump |
|
thermostat |
|
crankshaft |
|
water jacket |
The thermostat controls coolant (and, through it, engine) temperature by regulating the flow of coolant through the radiator. A bypass tube allows coolant to bypass the radiator and flow back into the water pump when its temperature is low enough that the thermostat is closed.
