About This Quiz

We love our cars, don't we?

There is nothing better than getting in your car over the weekend and taking a cruise! Along coastlines, or through a mountain pass. Just taking it all in as our vehicles do all the work.

But then... a clunk, whizz, and vrrrrr come from the engine... what could be wrong? Can I fix it? And more importantly, how much will it cost? It stands to reason. Cars are made up of many, many thousands of parts all working in perfect harmony to get us from A to B. And when things go wrong, we get worried!

Luckily, we are far better off now than in the past. Cars are just infinitely more reliable now than they were 60 years ago. They also have so many more onboard systems that help detect problems even before they can become something more serious.

That said, do you think you have what it takes to troubleshoot a range of common car problems? In this quiz, we will give you a scenario or question and test your knowledge of what the likely cause of the problem is.

Sounds easy, doesn't it? Let's hope you know you catalytic converters from your oil pumps!

Good luck!

Your car won't start. It is totally dead and the engine won't even turn over. What do you check first?
The terminals on the battery as one may be loose
Whether it has gas or not
The sparkplugs
The carburetor
Correct Answer
Wrong Answer

An engine that is totally dead and won't turn over could have a number of causes. The first thing to check is that the terminals are connected to the battery. You won't believe how easily these can actually come off.

Put in more gasoline
Stop the car and check the oil level. Put in oil if necessary
Check the coolant level in the car
Check the brake fluid level

Your engine is on fire, put it out!
You don't need to fix it. This means your engine is running clean.

Your engine has started making a high-pitched squeaking sound. The first thing you should check is the ___________
Oil filter
Fuel filter
Crankshaft
Fan belt or other belts

Oh, no! Your car won't start. It won't turn over, and the dashboard lights don't even come on. And it's a brand new battery you have only had for a few months. What should you now check?
Distributor cap
Alternator
Hi-tension leads
Engine block
Correct Answer
Wrong Answer

The alternator helps keep your battery charged. If it is not working, the battery will slowly drain of power. A dead alternator will eventually mean a car that is going nowhere. Luckily, they are fairly easy to replace.

Approaching your car, you notice a puddle under the engine. What should you check?
Check the coolant level in your radiator. It is probably leaking
Check the brake fluid levels
Check that your oil or fuel filter is not leaking
Don't check anything, it's nothing to worry about
Correct Answer
Wrong Answer

A leaking radiator is a massive problem. If not fixed, coolant levels will drop, your engine will overheat and could seize. A quick fix is to use a radiator sealant, but ultimately, it will need to be replaced.

Check the oil level
You are running out of gas
Your car's engine is overheating
It's not serious, ignore it
Correct Answer
Wrong Answer

An overheating engine is no joke. If the radiator has no leaks and you cannot see coolant on the ground once the car has been standing, then the problem could like with the thermostat. This helps to regulate the engine temperature and if broken, can make the engine overheat.

Your car is pouring black smoke out the exhaust. What should you check?
The fuel/air mixture. The car engine is running too rich.
Make sure the engine is not on fire
The catalytic converter
None of the above

Your car has a lack of power and you notice the smell of gasoline. What should you check to fix this?
The oil filter
The sump
The carburetor
Sparkplugs
Correct Answer
Wrong Answer

A problem with the fuel/air mixture could mean that the engine runs poorly. The carburetor regulates this and should be the first thing you check.

Sump
Crankshaft
Pistons
Distributor cap
Correct Answer
Wrong Answer

A spark is needed for the engine to turnover as this helps ignite the fuel/air mixture. The broken distributor means that the spark won't happen.

Your vehicle is suddenly very loud, especially underneath along the length of the tailpipe. What should you fix?
The fuel filter
The oil filter
Hi-tension wires
The muffler
Correct Answer
Wrong Answer

Mufflers suffer wear and tear doing their job of keeping your car quiet. If they get a hole in them, they no longer do their muffling, hence a louder engine noise as the gases escape down the tailpipe.

Stop using higher octane fuel.
You have an oil leak, fix it.
None of the above
Correct Answer
Wrong Answer

Yes, a faulty ignition coil can cause a car to run, even though it has been switched off and the key removed. No, it's not the previous owner's ghost.

A car engine that has seized has done so why?
Not enough gas
The gas filter was clogged
Spark plugs broke
Not enough oil for lubrication
Correct Answer
Wrong Answer

It's that simple. A car engine uses oil for lubrication. If there isn't enough, thanks to an oil leak perhaps, the engine will seize. Sadly, there is no quick fix and hopefully it was noticed in time.

Check oil light
Brake warning light
Catalytic converter failure
None of the above
Correct Answer

The car heater
The water pump
The cabin air filter
None of the above
Correct Answer
Wrong Answer

The cabin air filter is found in the glove box in most vehicles. It helps clean the air coming into the cabin but can be clogged up with all sorts of nasties and then will start failing in its primary task. It is easy to replace.

Advertisement

If you are replacing the oil in your car, what else should be replaced at the same time?
Sparkplugs
Gas injection system
High tension leads
Oil filter
Correct Answer
Wrong Answer

As the new oil will flow through the oil filter, it too will need to be replaced to ensure the new oil stays clean and effective at lubricating the engine.

The front right hand tire is wearing excessively on the right hand side. What is wrong?
It is not a radial tire.
It is overinflated.
Your wheel alignment is out.
It needs a new inner tube.

You notice a rattling sound coming from underneath your car when you are driving. What is the likely problem?
The honeycomb mess within the catalytic converter has come loose
Worn tires
Your rims need replacing
None of the above
Correct Answer

Sump
Fuel pump
Crankshaft
Pistons
Correct Answer
Wrong Answer

A car needs fuel to start, it's part of the ignition process. If a fuel pump has failed, it will not be pushing fuel into the ignition system and the car won't start.

When starting your car at night, you notice that the interior lights dim. What could be the fault?
Starter motor
Pistons
Spark plugs
None of the above
Correct Answer
Wrong Answer

If there is a fault within the starter motor, it can often drain power during the startup process. That would cause the interior lights to dim. Replace it before it becomes something more serious!
