I believe that many car owners’ cars have been out of warranty and are directly maintained in the auto repair shop. However, some friends reported that the repairman forgot to install the air filter, and only discovered it a year later. So, what is the impact of running the engine without air filter for a year? Today we will talk about it in detail.

If the engine does not have an air filter, the impact can be said to be considerable, because suspended particles in the air will enter the cylinder unimpeded. Although the lubricating oil inside can indeed take away some, for some relatively large particles of impurities, it is likely that they will always accumulate between the piston and the cylinder. So when the engine is running, it will naturally aggravate the wear of pistons and cylinders. If it is serious, the phenomenon of "cylinder pulling" will occur. Whether it is the power output of the engine or the fuel economy, it will have an impact, so it must be done at this time. Install the air filter as soon as possible.

Air filterInstallstep:

1. First loosen the filter lock and remove the fixed nut.

2. Then remove the protective cover, check whether there is dirt inside and outside the filter housing, if any, wipe it off with a rag.

3. Then the air filter element can be installed. But it should be noted that the paper part of the filter element should not be touched with your hands, especially not to allow oil to contaminate the filter element.

4. Finally, install the corresponding parts in the reverse order of disassembly.

Then, some friends also asked whether the auto repair shop could be held accountable. In fact, this is really hard to say. Although forgetting to install the air filter is indeed a very big mistake, it has been a year after all, and they don't know if they have done any checks on the way. Secondly, if you want to hold the auto repair shop responsible, you must have sufficient evidence. If you are talking about yourself, it is normal for them not to admit it.
