This is why drivers need to pay attention to warning signs so they don’t end up paying thousands of dollars in repair bills.

The experts at Collision Motoring Services have listed the key points you need to know so you can keep driving stress-free.

The car’s engine light lights up

The first indication that something might be seriously wrong is when your car’s engine light turns on.

This is perhaps one of the most dreaded signs that any driver can see, but it does not necessarily mean that there is a serious fault.

It could be on due to something small, like a loose gas cap.

Although it shouldn’t be ignored as it could be something big.

A car’s engine light can come on for many reasons having to do with your engine, including the transmission, exhaust system, electronic powertrain controls, air/fuel delivery, or ignition system.

The experts say that while low engine oil can be a serious problem, it shouldn’t trigger the check engine light.

You should still be able to drive your car with the lights on, although this is not recommended unless you notice other signs, such as: B. a loss of power or a strange noise.

However, drivers are advised to have their car checked by a professional as soon as possible to avoid further damage.

Overheating is a constant problem

Car engines that need to be repaired or even replaced are particularly susceptible to overheating.

If your car is constantly overheating, it could be due to a variety of reasons. It is recommended to see a professional immediately.

One of the many reasons could be a faulty engine block. While cracks in it can be repaired, the entire engine may need to be replaced.

A loss of power

One of the most obvious signs of a problem with your engine is a noticeable loss of power.

The experts say immediate action is needed to prevent major problems from occurring and ensure your car functions as it should.

Ignoring the problem may result in you potentially having to replace the entire engine in the not too distant future.

The engine oil contains some additional ingredients

This states the obvious, but no matter what engine your car has, it needs oil to function properly and perform optimally.

If you have a warranty on your car, not using the correct engine oil for your type of vehicle could also void your policy.

The amount of time between an oil change varies depending on the make and model of your car

Advances in modern lubricants mean that these days a change typically takes place between 5,000 and 7,500 miles, with some taking up to 15,000 miles.

Your driving habits – such as whether you take long or short journeys or regularly drive stop-start or carry heavy loads – can also have an influence.

The weather conditions in which you typically drive can also affect how often you change your oil.

When changing your engine oil, watch for signs that the engine may have a problem.

You need to watch out for metal shavings in your engine oil. These chips are parts of your engine that have dissolved in the oil.

This is a problem that cannot be fixed.

Changing the oil helps keep the engine running smoothly, but it has no cleaning effect.

The experts recommend cleaning the engine thoroughly with a car engine cleaner.

A knocking noise comes from your engine

Drivers need to be aware of what is known as “rod knock.”

The constant, deep knocking noise is caused by the pistons in the cylinder hitting and is due to worn connecting rod bearings.

The noise often becomes more frequent at higher speeds, but persists even after the engine has warmed up.

Drivers should get this fixed as soon as possible as it can cause serious damage to the cylinder block and leave you with a hefty bill.

There are a lot of fumes coming out of your exhaust

Checking the condition of your car’s exhaust fumes will help you determine whether your vehicle has engine failure.

Black fumes could mean too much fuel is being burned, while blue or gray fumes could indicate a large oil leak.

White fumes could be caused by a coolant leak.

The experts once again warn that the continuous emission of exhaust gases must urgently be checked by a specialist in order to avoid costly repairs.
