Test Your Automobile Knowledge Quiz

1. What will happen if your constant velocity or cv joint is going bad?

Your vehicle backfire upon starting.

There will be a burning smell upon driving.

Your vehicle will produce smoke upon driving.

Your wheels will make a clicking sound upon turning the wheels.

Your vehicle shake upon backing up.

If your constant velocity (CV) joint is going bad, your wheels will make a clicking sound upon turning the wheels. The CV joint is responsible for transferring power from the transmission to the wheels, allowing them to turn at different angles. When the CV joint starts to fail, it can cause a clicking or popping sound, especially when making sharp turns. This is usually a sign that the CV joint is worn out or damaged and needs to be replaced.

2. What will happen if you place the spark plug wires out of origional order?

Your vehicle will backfire upon driving.

Your vehicle will backfire upon a complete stop.

Your engine will stall upon driving.

Your engine will backfire upon starting.

Your engine will misfire upon starting.

If the spark plug wires are placed out of their original order, it can disrupt the firing sequence of the spark plugs. This means that the spark plugs may not ignite the fuel-air mixture in the correct order, leading to a misfire. A misfire occurs when the fuel in the cylinder does not ignite properly or at all, resulting in a rough running engine or even stalling upon starting.

3. What will happen if your wheel barrings need tightened?

Your wheels will rust and decay upon driving.

Your vehicle will not ride smooth upon driving.

Your tires will fly off of the wheels upon driving.

Your tire will have blowout upon driving.

Your engine will stall upon starting.

If your wheel bearings need to be tightened, it means that they are loose. When wheel bearings are loose, they can cause vibrations and wobbling in the wheels, which leads to an uncomfortable and rough ride. This can affect the overall stability and control of the vehicle while driving. Therefore, the correct answer is that your vehicle will not ride smooth upon driving.

4. What will happen if you do not screw your spark plugs in tightly or correctly?

The plug will blow out with a pop and the engine will turn off immediately after starting.

Your vehicle will smoke soon after starting.

Your plug will rust and decay after driving.

Your vehicle will shake badly after driving.

Your plug will fall out soon after driving.

If the spark plugs are not screwed in tightly or correctly, there may be a loss of compression in the cylinder. This can result in a backfire, causing the plug to blow out with a pop and the engine to turn off immediately after starting.

5. What are parts of a distributor?

Rotor and drum and rod.

Camshaft and throttle and gasket.

Filter and gasket and rod.

Cap and rotor and camshaft.

Drum and throttle and pump.

The correct answer is "Cap and rotor and camshaft." In a distributor, the cap is responsible for distributing the electrical current to the correct spark plug at the right time. The rotor spins inside the cap and transfers the current to the appropriate spark plug wire. The camshaft, on the other hand, is responsible for controlling the opening and closing of the distributor's points, which regulate the timing of the electrical current. Therefore, the cap, rotor, and camshaft are all essential parts of a distributor.

6. What do you do and in what order if your brakes go out while driving an automatic?

Emergency brake only.

Emergency brake then first gear then second gear.

Second gear then first gear then emergency brake.

First gear then second gear then emergency brake.

Emergency brake then second gear then first gear.

In the event of brake failure while driving an automatic transmission vehicle, take the following steps in this order:

Emergency Brake: Apply the emergency brake (parking brake) immediately to initiate braking.

Second Gear: Shift to a lower gear, usually Second (2), to engage engine braking and further slow down the vehicle.

First Gear: If needed, shift to the lowest gear, often First (1), to maximize engine braking for additional stopping power.

This sequence helps regain control, slow down the vehicle, and address the brake issue safely by utilizing both the emergency brake and engine braking mechanisms.

7.

What will happen if your catalytic converter is going bad?

Your vehicle will shake upon driving.

Your vehicle will produce smoke upon starting.

Your engine will turn off or stall upon a complete stop.

Your vehicle will backfire upon driving.

Your engine will have a loud ticking sound upon driving.

If the catalytic converter is going bad, it can cause a restriction in the exhaust system, leading to poor engine performance. This can result in the engine stalling or turning off completely when the vehicle comes to a stop. The catalytic converter plays a crucial role in reducing harmful emissions, and if it is failing, it can disrupt the proper functioning of the engine.
