[Daily car maintenance] Cadillac XTS is deeply maintained, and the entire operation process is here!

10 Hello everyone, this is a column focusing on car repair and maintenance. There are car mysteries you don’t know, and it will teach you how to avoid the big pits on the road of car ownership. I believe that not only you but also many people have a certain sense of obscurity about the car aftermarket, which will help you uncover the unknown stories of car repair and maintenance.
As a medium and large luxury model under Cadillac, sales of the XTS have been crushed by the German troika. But does sales really speak for itself? Today, I had a close contact with XTS. I will explain this XTS in more detail when doing major maintenance.
There are surprises everywhere. I saw a manual sunshade in the window of the rear door. The configuration is quite high. This is unlikely to be seen in BBA models, especially if the sunshade is electric.
Then we started to change the oil.
Thanks to the power system layout of the front drive, the XTS engine cabin is designed to be very full. But fortunately, there is no messy layout, and the overall visual sense is very good. The 2.0T turbocharged engine is used in many of its models.
The air filter element is very large, so as to ensure a relatively high output power. Let’s make a comparison between the old and the new, the dirty air filter will seriously affect the air intake efficiency, insufficient air intake, how to release a strong power.
For the new oil filter elements, American models rarely use paper oil filter elements, and most of them use iron oil filter elements.
The engine oil uses Castrol multipole protection model is 5W-30. This oil cannot be used in extremely cold areas, not in the northeast. Because the mobility of low temperature is very general, in the cold north, the winter temperature can reach an astonishing 30 degrees below zero. At this time, the oil will become very sticky.
XTS has a very strong Yuanbaoliang. In fact, I feel that the power unit of the front drive platform is very difficult to layout, the whole weight ratio and handling of the car body can not be compared with the rear drive model, and what is even more annoying is the smaller steering angle. The main reason why the major manufacturers are still developing models of the front-drive platform is mainly because of the cost.
Oil release, gravity oil change is now mainly applied to the oil change process. At present, another method in the post-repair market is to use a pumping unit to extract the residual oil from the engine, and the effect is very good. But the prerequisite is that the hole in the oil ruler is big enough.
Start to change the gearbox oil, although the cycle machine is used to replace the gearbox oil. But it is best to release the oil deposited inside the oil pan of the transmission first. Because the gearbox oil deposited at the bottom of the oil pan contains a lot of impurities, the impurities can be released by inertia by using this gravity method.
As much as five liters of gearbox oil was released by gravity. This mass is large enough for a general-purpose gearbox. It is common for many models, including the LaCrosse, to be able to release about two liters of fuel.
Whether it is engine oil or gearbox oil, the temperature requirements are extremely strict, it can be said that it is very sensitive to temperature. This is why many cars have oil radiators, power oil radiators, gearbox oil radiators. The goal is to have only one. Keep the oil at a constant temperature. On the water tank of XTS, the radiator of gearbox oil is integrated, and the gearbox oil is cyclically replaced through the heat dissipation pipeline.
Install the special hose for the gearbox oil circulation machine, and the other end is directly connected to the circulation machine.
The old oil and the new oil that need to be filled are clearly marked.
The power supply of the circulation machine uses the 12V power supply in the car, which can be directly linked to the terminal post of the battery when it is replaced.
The whole operation process of the circulation machine greatly saves the labor intensity. Now only one person can do it, and can achieve higher replacement efficiency.
This is when changing the gearbox oil, see the embodiment of the contrast oil, is not very intuitive. In fact, the working principle of the whole machine is very simple.
In fact, the displacement of this engine is not American, at least more than 5.0 to really have the spirit of the United States. Maybe even deep-pocketed Americans can’t bear the global energy crisis. However, seeing the latest news that oil may become a renewable resource, if it can be realized, then the era of high emissions will come back.
