Your Volvo or Toyota Exhaust System Explained

  • Friday, August 03, 2018

Here at ACC UK Ltd, multi award winning Independent Volvo and Toyota Service, Repair & MOT garage based in Farnborough, Hampshire, we like to bring you handy hints and tips on how to maintain your Volvo or Toyota and how to save money on your annual car running costs. We also like to keep you informed of changes to laws relating to driving and car ownership.

The blog this week is about the role your exhaust system plays and the issues to look out for that indicate there could be a problem. Read below to find out more.

Depending on the make and model of your vehicle, your exhaust system will vary with regards to where it is positioned and how it has been designed. However the purpose and functionality are essentially the same. This is to take the emissions from the front of the vehicle away from the car and into the atmosphere. If your exhaust system is damaged – usually through corrosion (rust), this could potentially lead to harmful gases entering your Volvo or Toyota. This is not a desirable situation to be in as it could cause serious health problems for all those inside the vehicle.

So what are the basic components that make up the exhaust system?

The Exhaust Manifold: it transports the gases from the engine into the exhaust system via the cylinder heads.

The Catalytic Converter: this takes the harmful exhaust gases (such as carbon monoxide and hydrogen monoxide) and converts them into water vapour and carbon dioxide. These in turn pass through a silencer.

The Oxygen Sensor: also known as a lambda sensor, (See previous blog) works out how much oxygen is located inside the exhaust, your Volvo or Toyota computer can then determine how much fuel should be added for optimum fuel efficiency.

The Exhaust Pipe: this part of the system which you can see at the rear carries the gas from the engine and releases it from the back of your Volvo or Toyota at street level.

If you notice rust or corrosion you should seriously think about having your exhaust replaced at your local independent garage. During servicing and MOT’s the garage can inspect the exhaust when it is up on a ramp. It is difficult for you to inspect this part due to its proximity to the ground. That is why it is important to maintain regular servicing of your Volvo or Toyota. It is possible to weld patches over holes and corrosion, however this is likely to be a very temporary fix as the corrosion can return. The corrosion can occur because of the elements – your exhaust is near a wet road and exposed to grit and salt etc – over time these parts will perish – it is inevitable. If you feel your Volvo or Toyota has become noisy, there could be a hole in the system or damage to the silencer. If you notice poor fuel economy there could be an issue with the oxygen sensor, a hissing noise could be a cracked exhaust manifold, a knocking noise could be a broken bracket or a pipe that has become disconnected from the box. This could occur when going over large speed humps or parking on kerbs. None of these issues will resolve themselves. It is much more prudent to take your Volvo or Toyota to your local independent garage for further investigation. An honest garage will tell you exactly what the problem is, how to remedy it and how much it will cost. Don’t ignore it as you do not want to expose yourself or your passengers to the possibility of harmful gasses being brought into the car because there is a fault in the exhaust system.
