How to Diagnose Problems with Your Exhaust System


Exhaust system

   Exhaust system is a tricky thing which replace often costs a lot of money. Fixing of a problem with your exhaust system when it just first appears is much less expensive than waiting for the broken exhaust to cause further problems elsewhere in the engine. The exhaust is a vital part of the car’s internal workings. It not only reduce the noise of your engine, it also makes sure that the fumes generated from burning petrol are kept away from the passenger cabin. More so, it ensures the smooth running of the engine, maintains maximum fuel efficiency and reduces the quantity of harmful emissions generated by the truck.


Engine noise

   One of the easiest ways to see that your exhaust system needs repair is a loud noise coming from the engine. If the noise your engine makes changes dramatically then you should always take your truck for inspection by a professional as this is almost always a sure sign of a serious internal problem.


Rattling noise

   If you hear a persistent rattling noise coming from the exhaust area when the engine is running, this is a straight indicator that your catalytic converter is failing. This is one of the most expensive components of the exhaust system and is often a target for thieves. If you hear the rattling then it is definitely still in position, you need to replace it almost immediately.



   If you feel vibrations when you use the pedals which are new or stronger than usual, this could be an indicator that there is a leak somewhere in the exhaust system. If the hole is large then you might also hear a low rumbling noise whenever the engine is switched on. Look out for pools of fluid underneath the truck and take your truck to the service as soon as possible.


Visual checks

   Some problems are very easy to spot simply by looking at your exhaust pipe. Heavily rusted and split exhausts are easy to see from the outside. These problems can be just as serious as any of the internal problems which can affect your exhaust and should be given the same amount of attention. If you see that your exhaust has become heavily rusted then there are steps which you can take to try and clean off the majority of the rust. If you see that you have a hole in your exhaust or if the pipe is split then you should take your truck into a service to repair it by a professional.


Fuel efficiency

   If you suddenly find that you are having refuel more often than usual, it may be that you have a problem with your DPF. Moreover Alpha Fleet Service provide 2-stage DPF Cleaning which you can order simply by filling an appointment form or by calling our number 253-231-5500 .

The problem might not be to do with your exhaust, but any of the changes listed above tend to be indicators that there is something wrong with your engine which requires immediate attention and repair.
