Detailed strategy for 80,000 major maintenance

September 5, 2024

My car has been taken good care of, although it has reached more than 80,000 kilometers, but it still does not diminish my care for him. How should the maintenance be the most thorough when it comes to 80,000 kilometers? How can you really make your car look like a new car? The next personal post allows me to share your unknown secrets with my friends from the perspective of the old Prado owners.

What is the maintenance of 80,000 kilometers of Prado?

Combined with the maintenance manual, the oil and water of the whole vehicle with 80,000 kilometers of maintenance should be replaced, and at the same time, the spark plugs should be replaced, and the specific contents should be combined with their own car conditions. I roughly put the contents of their own maintenance to do a collation for your reference.
1. Change gearbox oil.
2. Replace the inner filter of the gearbox. (this will be described in detail later on why I have to change this.)
3. Change the brake oil
4. Change the front transfer tank oil (also known as front axle oil)
5. Change the antifreeze
6. Clean ternary catalysis clearly (whether you can do it or not, depending on your car condition)
7. Clean the carbon deposit in the engine cylinder.
8. Clean the fuel injection nozzle
9. Replace the spark plug
10. Change the oil (Castrol 0W40)
11. Replace the gasoline filter

The carbon accumulation in the cleaning cylinder mentioned earlier can actually be omitted. You can find a small shop outside to do it, but why do I do it in the SSSS store? The main reason is that I replaced 6 spark plugs, and when I removed them, I could wash the carbon deposits in the cylinder, so I did this project. It needs to be noted that this cleaning agent is not added to the gasoline tank. It is foamed by the machine and hit in the cylinder, and then it is sucked out after a period of time, and then washed clean with an air gun, so this needs everyone’s attention.

Brake fluid is general-purpose by Lexus, about 3 vials will be enough.

There are roughly these, and the oil and gearbox oil have not been changed.

The gasoline filter element still needs to be replaced. Prado’s design is still relatively humanized. It is in the cabin. The external filter element is relatively convenient to replace, and it is not difficult. The reason for replacing this is that the domestic oil products are not good. In one, this filter element is very small, and it is good for the car to use about 20,000 yuan. Generally speaking, in addition to having a good look at the oil road, there are all kinds of filter screens.

I changed the spark plug for 80, 000 kilometers. I personally suggest that everyone run and change it again. RAV4, the eldest brother next to him, has already run 140000 before he begins to change the spark plug. Judging from the spark plugs I replaced, they are basically fine, and it’s absolutely no problem to run to 100000, so if you want to save some money, it’s okay to change it later. Officially, it seems that 8-100000 is being replaced.

To explain here, the spark plug must choose the same spark plug with the original car, try to make the rules and parameters consistent, not the more expensive the better, suitable for their own is the best.

Spark plug this is the brand of electric post, you will find that the original model is 16, now the new model is 20, SSSS store explained that there is no difference, before the old model also had three on the left and three on the right with a different brand.

When I changed the rear axle oil, it was already gray when I changed it for 40,000 kilometers, indicating that it had already been filled with water. During this replacement of 80,000, I also took a special look at it. There was no water in it, and the oil was good. So remind everyone not to wade frequently, because there are air vents at the top, it is easy to enter the water when the wading is too deep, which leads to the mixing of oil and water and the decline of quality.

It’s already dark, but it’s still very liquid.

2. Where can I save money?

Where can I save it? In fact, as long as the money is in place, there is nothing wrong with changing it. From the economic cost point of view, to maximize the service life, thus saving costs, there are still some places to save money.
1, all kinds of cleaning, these projects can actually be done outside, and the price is much cheaper than inside the store, these contents can be done outside a suitable and reliable storefront.
2. [noteworthy] three-way catalytic cleaning, Prado model disassembly three-yuan is more painstaking, if there is no lack of money can be dismantled to clean, that is the cleanest, the cost is about 80-1500. If you don’t want to take it down, hit the bottle and clean it. It should be noted that excessive detergent, oxalic acid and other substances are easy to damage the sensor inside, you should pay attention to this, and if you do not disassemble for a long time, the sensor is easy to rust.
3, spark plug, run a full kilometer and then change, to avoid excessive maintenance, I belong to over-maintenance.
4, gearbox filter, change it according to your own situation, which will be introduced in detail later.

3. Is it necessary to replace the gearbox filter for 80,000 km maintenance?

Many riders will ignore the replacement of the gearbox filter during major maintenance. This thing, in fact, a lot of major maintenance will tell you that you do not need to be replaced, such as maintenance-free, my personal view still needs to be replaced, of course, this replacement requires a price of money, the filter screen is 460 yuan, the gasket is about 100. The reason for the change is that whenever it is a filter screen, its function is to filter impurities. If these impurities are not replaced for a long time, the gearbox will be damaged, and the iron filings in one will never be replaced. So I decided to replace the gearbox strainer at 80,000 kilometers at this point. This really found a lot of dirty impurities in the actual replacement process, it should be noted that my maintenance oil and water are all replaced in the SSSS store, so there is no problem of bad oil products. In a situation where I usually cherish the car and do not have a big throttle to pull the rickshaw, the road condition of commuting to and from work is also very good, so my own filter can be removed. But if the situation of cross-country or long-term traffic jams is better than mine, the filter may be dirtier.

This is a new gearbox filter. You can see that there is a thin layer of iron mesh inside, which plays a filtering role. There is a filter of cotton material on the market, and this needs to be paid attention to. For example, Audi cars and Volkswagen cars all have cotton strains. the filtering effect will be better, but at the same time, the cotton material is also easy to cause valve body blockage, which needs to be watched when you choose and buy. I strongly recommend that you buy this material of iron net here.

Gasket, replace the necessary gasket.

This is the gearbox oil replaced by my gearbox. We found that we don’t have to change it. The color is very good. This may be the reason for my replacement of 50,000 kilometers.

In the close-up of the new filter, it is worth noting that this mouth is an oil suction hole, from which the gearbox oil is sucked up.

This is the oil outlet, through which the filtered oil enters the valve body.

Here comes the point! Look, this is the oil pan of the gearbox within 80,000 kilometers of my car. Have you found that the square part has been wrapped in iron filings impurities, indicating that there are indeed a lot of impurities in it? just because my car usually drives more carefully, there are not a lot of impurities. The function of four iron absorbers is to absorb impurities and prevent iron filings from overflowing. This design is still very scientific. Is that where the guidance is? That’s the four little squares.

If you draw it casually with your hand, you can see that there is a layer of impurity on it. This impurity is precipitated in the bottom shell all the year round.

All right, this is the filter screen of the original factory, above is the valve body, understand where the oil suction hole I mentioned earlier is.

Take a look at how many impurities are on the magnet? This can not be replaced through the gearbox circulation machine, only by hand. And the gearbox filter needs to be replaced.

Clean, look comfortable, now replace the gasket, tightly sewn.
What we need to pay attention to here is where is the oil dipstick in our gearbox? How to tell if there is more or less gearbox oil? All right, just in time you see the protruding pipe in the oil pan of the gearbox. Its design has a protruding table. When the oil volume is too full, the excess oil can be released by gravity. At the same time, the amount of oil in the gearbox of the whole car is consistent. This design is really smart. I didn’t know how to measure the gearbox oil before, but I learned it this time, so do you have such a professional and standard maintenance master when you are outside? Too much oil in the gearbox and less fuel in the gearbox really has a great impact, and the damage to more cars is also great. Have you learned this little secret?

4. What are the details of domestic Prado 4000 that you don’t know?

The first little secret is that there are iron filings in the oil pan of the gearbox, which needs to be removed manually before it can be removed, so it is recommended that you replace the gearbox filter during major maintenance.

2. Only the domestic car has a temperature distributor. When the temperature of the gearbox is too cold, the valve body of the distributor is closed, so as to protect the gearbox and let her temperature rise as soon as possible. When the temperature is too high, the distributor valve will be opened, thus taking away the excess temperature and protecting the gearbox.
