The particle filter is a fairly new invention that aims to take out harmful particles from the exhaust gases of modern diesels. It has long been discovered as the miracle solution to these pollution complications. However, it doesn’t work as well as designed and triggers more complications than it solves, which is why we will see in this article when changing the particulate filter of a Lexus ES? . To achieve this, to begin with, we will identify what the particle filter on your motor vehicle is utilized for, and then when to change the particle filter on your Lexus ES.
What’s the purpose of a Lexus ES’s particulate filter?
So we start our article with the reason to do this component recently built in into diesel vehicles. As we mentioned quickly in the introduction, the goal of this filter was to solve the complications of pollution and harmfulness of exhaust gases from Lexus ES vehicles. Its operating principle is to store exhaust gases that are unburned or that still contain harmful particles, and when it is at a adequately high temperature to cause a second combustion that will finish burning and eliminate all these carcinogenic particles. Unfortunately, to reach this very high engine unit temperature, you have to be on the highway or have your Lexus ES engine unit revving up. So we have realized with time that vehicles that are mainly on short trips or in the city do not enable the particulate filter to burn these gases and we will see in the next section that these complications can force you to change the particulate filter of your Lexus ES .
When to change the particulate filter of a Lexus ES?
In this section we will identify what you are certainly drawn to here, whether it is required to change the particulate filter of a Lexus ES and if so, when?
Is it required to change the particulate filter on Lexus ES?
There are 2 types of particulate filter for vehicles, a particulate filter with additive, which does not concern the Lexus ES, but which needs to be recharged every 120, 000km with an additive that enables the regeneration of the particulate filter and consequently to burn all those harmful soot. The second one, the one we are enthusiastic about in this article, works with precious metals that will produce a chemical reaction at high temperature and cause the regeneration of the filter and the evacuation of the carcinogenic materials. However, as mentioned earlier, it necessitates very high temperatures, if these are not reached the filter will clog. If the filter is not regenerated manually, drive at high speed for about 20 minutes to reach this temperature and thus regenerate your filter, you will clog it and risk damaging your turbo, your EGR valve or your engine unit. If you need to clean the EGR valve of your Lexus ES due to your particulate filter, do not hesitate to look at our content page on this subject to identify what the procedure is.
When to change the particulate filter of a Lexus ES?
As we explained before, a particulate filter is designed to last the life of the car, however some of you may wonder when it is required to change the particulate filter of its Lexus ES? Be aware that this part is extremely expensive, labor is not the main problem because it is easy to access. But the component itself will vary enormously in price depending on your motorization, you can still count a range between 700 and 2000€. This change should just be considered in the case of a completely clogged particle filter. If you don’t repeatedly take the motorway, we advise you, every month to drive 10 minutes on the motorway at least 3000 rpm . In spite of everything, the current particulate filter have not been well designed and remain troublesome, it is considered that due to the lack of a sufficiently regular temperature rise and other design complications, you should start planning to change your particulate filter from 200, 000km if you have a use of your XX that is more urban and a little more if it is mixed .
