Transmission oil for UZ-DAEWOO N - described in detail

Depending on the manufacturer and year of manufacture, a variety of oils could initially be filled into the Daewoo Nexia gearbox. Most often, this is an inexpensive mineral water; cars assembled in Korea could sometimes be filled with synthetic and semi-synthetic transmission fluids. Be that as it may, factory oil often only lasts for the break-in period, and after that it absolutely requires replacement.

How often does an oil change need to be made?

To begin with, we suggest you sort out the question of when to change and fill new fluid into a manual transmission of a Daewoo Nexia 150 2011 or another year of manufacture. According to official data from the automobile manufacturer, the oil initially poured into the transmission at the factory must be used throughout the entire life of the vehicle. But the manufacturer also does not specify what the specific service life of the car should be. Therefore, the car owner will not be able to check whether this resource has expired or not.

Nexia gearbox

In order to prevent serious malfunctions in the operation of the Daewoo Nexia gearbox and avoid large financial costs, it is recommended to change the transmission oil after 100-150 thousand kilometers. Or every 7-10 years. If there are malfunctions in the operation of the unit or difficulties with switching speeds, the fluid can be changed earlier. The best option is to replace it every 100 thousand kilometers.

Consequences of untimely replacement

8- and 16-valve Daewoo Nexia requires periodic replacement of transmission oil, since the additive package in the lubricant loses its properties over time. As a result, it becomes inoperable. Because of this, the liquid cannot provide the proper level of protection for rubbing surfaces. The loss of basic properties will lead to foaming of the working substance, which will ultimately cause scuffing of the main gear. As a result, the gears of the transmission differential will begin to hum, that is, the operation of the gearbox will be accompanied by a hum.

After 500-1000 km, the teeth on the gears will be destroyed. And this will lead to the transmission jamming. The driver will not be able to engage one or more gears. In Nexias with automatic transmissions, oil is also used to cool the unit. Failure to change the lubricant in a timely manner will result in kicks and jolts when shifting gears.

History of Nexia

This Korean middle-class car was presented to the public in 1986. The development was carried out by German specialists (). The car was created on the basis of the Opel Kadett E, which was widespread at that time. "Nexia" began to be produced for residents of developing countries. Since 1995, cars have become available to citizens of the former Soviet Union. By the way, this car is known to Korean residents under the name “Daewoo Cielo”.

Ergonomics of Daewoo Nexia

The car stood out, first of all, for its low price. It cost no more than Russian front-wheel drive VAZs. The car was quite reliable, unpretentious in use, was ahead of Russian cars in terms of these characteristics and was not inferior to imported middle-class models. Replacing broken parts was easy due to their availability. All this explains the ubiquity of this machine.

However, Nexia gradually began to lose ground. The last car of this model was released four years ago. After this, the Korean manufacturer began producing the Daewoo Gentra.

Checkpoint on the Daewoo Nexia - what will we use?

When purchasing oil, pay attention to the release date.

Despite the fact that the manufacturer declares the indefinite use of gear oil in the Daewoo Nexia gearbox, it needs to be changed.

Experts advise not to exceed the mileage before an oil change of 100-120 thousand km . Otherwise, there will be expensive repairs - synchronizers, seals, shafts will not last long on old oil.

Oil Standards

In the event of a forced oil change, the plant itself recommends using fluids of the SAE 80W , class not lower than GL-4 . In cases where the vehicle is operated in low temperature conditions, the recommended viscosity should correspond to the standard 75W-90 GL-4 .

The plant does not give clear recommendations regarding the composition of the oil, although initially it pours mainly mineral oils into the gearbox. The only advantage of mineral oils for gearboxes is the price.

Types and manufacturers

Otherwise, synthetic and semi-synthetic fluids work much better. This affects both the lubricating and washing properties of the oil and its durability. According to experts, the brand does not play a special role, although each driver has his own preferences. Castrol Syntrans 75w90 is perfect for Nexia .

Hochleistungs-Getriebeoil GL4+(GL-4/GL-5) 75W-90.

In addition to this oil, you can choose more inexpensive analogues that are no worse than the same:

Castrol DriveLine 75W-90 Syntrax Universal;
Castrol TAF-X 75W90;
Castrol SMX-S;
Hochleistungs-Getriebeoil GL4+(GL-4/GL-5) 75W-90;
Hessol Hypoid Getriebeol SAE 80 W 90 GL-5.

Nexia engine oil

As for brands that produce oil, Nexia owners have a wide choice. The manufacturer does not make any clear recommendations. The only condition is compliance with the viscosity characteristics. This indicator is determined in accordance with the climate and the level of average load on the engine.

Requirements

The engine can be filled with both semi-synthetic and synthetic oil. The use of mineral water is not recommended.
According to API standards, the oil must have a level above SM/CF.
5W-30 is used exclusively at average temperatures below -20℃.
The average climate zone allows the use of 5W-40 and 5W-50.
For southern regions, preference is given to 5W-50, 10W-40 and 10W-50.

Volumes and timing of replacement

As for the amount of oil that needs to be poured into the Daewoo Nexia engine, it is the same for both types of internal combustion engines - 3.8 liters, the only difference is that the 16-valve engine needs a little more - 150-200 grams. This is where the technological features of the engine components and assemblies affect.

The lubricant should be changed every 10 thousand km (about a year) - this is regulated by the manufacturer’s standards. Even if Nexia is idle most of the time, this does not affect the timing in any way - the oil deteriorates over time and its quality is lost.

If the car is used in harsh conditions, then the replacement period is reduced by half.

The best motor oil. does it exist?

used oil loses its original composition, loses its lubricating properties and additives
The viscosity level is significantly reduced, the oil foams and oil starvation occurs, as a result of which the rubbing parts of the manual transmission are subject to accelerated wear, and scuffing appears on the gearbox gears

To avoid the above problems, you must promptly:

checking the fluid level. This must be done when the gearbox has cooled down every 8-10 thousand km. The fluid should be level with the bottom edge of the filler hole.
checking the gearbox housing for the presence or absence of damage, oil leaks, etc. If leaks are detected, you must contact a diagnostic service
analysis of oil by color, smell and content. The liquid should not have a cloudy color, there should be no sediment or metal particles in it. You should also pay attention to whether the oil is cloudy, dark, or clear in color.

Level control and topping up

Before changing the lubricant, you need to make sure that its level is normal. If the check shows a critical lack of fluid, you need to carefully inspect the unit for leaks. Visually assess the condition of the transmission - the gearbox should not have cracks or other signs of leaks. Otherwise, the problem must be solved.

Visually familiarize yourself with the process of replacing transmission fluid in a Daewoo Nexia car in the video (author - Alexandr Borziy).

To diagnose the oil level, do the following:

Place the front left side of the car on a jack. The inspection hole is located in an inconvenient place. You can try to get to it from under the hood, but it is more difficult.
Unscrew the left wheel, if you look in the direction of travel of the car. A wheel wrench is used to unscrew the bolts.
After dismantling, next to the CV joint (constant velocity joint), you will be able to see a plug in the form of a bolt. You need to unscrew it with a wrench.
If the fluid level is normal, then after unscrewing the plug you will see grease near the lower hole.

Tools

In order to replace the fluid in the gearbox of a Daewoo Nexia, you will need the following tools and accessories:

jack;
syringe;
13 mm socket head;
17 mm socket head;
19 mm wrench;
oil directly;
transmission pan gasket;
container for draining used lubricant.

In order to choose the right gasket, it is first recommended to inspect the transmission pan from below. This is due to the fact that there are two types of pallets, having 10 or 11 holes - the number of holes must be checked before purchasing a gasket. In addition, you don’t have to buy a gasket, but remove the pan and cut it out yourself from paronite, or simply replace it with a sealant, which in practice copes well with the task.

Procedure for changing transmission lube

How to change gearbox oil? To complete the replacement procedure, you will need 10, 13, 17 socket wrenches and a nineteen millimeter wrench. You also need a jack, a bucket for draining used oil fluid, a large syringe or oiler.

First you need to change the pan lining in the transmission. Look under the car, count the number of holes in the pan. There should be ten or eleven of them. The cover you purchase must have the same number of holes. Filling requires 1.8 liters of synthetic/semi-synthetic lubricant 80W85, 75W80, 75W90.

The sequence of actions should be as follows:

This completes the procedure for changing the transmission oil. After some time, check the amount of lubricant and make sure there are no leaks. If leaks are detected, eliminate their cause and top up the oil product.

Normal operation of the gearbox is impossible without lubricant. Thanks to oil, rubbing components and transmission elements do not wear out so quickly. This is why the fluid should be changed periodically. How to change the oil in the Daewoo Nexia gearbox and what will happen if you do not replace the lubricant on time, you can find out from this material.

How to change the lubricant yourself?

You can replace the working fluid with the help of specialists at a service station or yourself. Let's look at the process of changing it yourself.

Preparation

Before completing a task, you need to prepare. Buy two liters of lubricant and prepare the tools:

a set of wrenches or socket heads (you will need tools for 13, 17 and 19);
jack;
medical or construction syringe;
new transmission pan gasket;
an old bucket, basin or cut-off bottle for collecting waste.

Before purchasing a gasket, be sure to inspect the pan on the transmission. On sale you can find two types of pallet gaskets, which are mounted with 10 or 11 bolts. Therefore, when buying a seal, make sure that it suits you. If it is not possible to purchase a gasket, you can make it yourself from paronite. As a last resort, if there is no seal, the perimeter of the pan must be coated with sealant.

Detailed instructions for changing the oil are given in the video (the material was filmed and published by the Expert R channel).

Stages of work

The replacement procedure must be performed in a garage with a pit or on an overpass:

Get under the bottom of the car. If there is protection on the engine, it must be removed. To do this, unscrew the bolts that secure it.
Using a wrench or a 10mm socket, unscrew the transmission pan screws. First remove the bolts at the front. Having done this, place a container under it. It is advisable to use a basin, as oil will begin to drain from the pan.
After draining the waste fluid, completely remove the pan. The gasket may tear; be sure to remove any remaining gasket from the area in contact with the transmission. In practice, 1.5 liters of fluid comes out of the pan, and the remaining volume remains in the crankcase. To completely get rid of used grease, lift the left front wheel with a jack. Raise it as high as possible.
Using a 13mm wrench or socket, unscrew the inspection hole bolt. It is located on the right side of the transmission when looking at the car from the front, next to the CV joint. After dismantling, the bolt should be washed from the inside. Thoroughly clean the loose magnet located in the plug.
When fluid stops dripping from the gearbox, the pan must be replaced. Before installation, clean the seat from any remaining lubricant and sealant. First, a new gasket is installed on the pan; if it is missing, use sealant. There is no need to screw the control plug back in.
The main stage is pouring new fluid into the box. To fill the transmission with oil, twist the breather located at the top of the transmission. Remove the plastic cap from this element and unscrew it with a head or a 19mm wrench. Place a funnel or watering can in the hole. And slowly pour liquid into it. Fill the oil into a syringe first, it will be more convenient. Lubricant is poured into the transmission until it begins to flow out of the control hole of the unit. Then the bolt can be tightened.
Reinstall the breather and tighten the inspection hole plug. Perform all assembly steps in reverse order. Start the engine and drive a few kilometers. Speeds should change without difficulty. After replacement, the box may be noisy for some time, but this will go away over time.

Price issue

When performing work yourself, there is no need to spend money on service stations. You just need to buy lubricant. The cost of gear oil depends on the manufacturer. For example, one liter of universal “Mannol 80W-90” costs the buyer 212 rubles on average. Castrol 80W-90 lubricant costs about 350 rubles per liter canister. The cost of original Toyota oil of the same volume is about 730 rubles.

Instructions for carrying out work

It is necessary to replace the lubricant on the overpass. The replacement operation is carried out in several stages.

If there is protection on the engine, remove it.
The transmission pan bolts will need to be loosened. Tighten the bolts in the front area of the pan and place a prepared container to drain the old “consumables”.
Once you have drained all the grease, you can remove the pan. If the gasket is not damaged, it will still need to be replaced.
As a rule, only 1.5 liters of lubricant comes out of the crankcase, approximately 200 g remains in it. If you want to perform a complete drain, you will need to raise the left front wheel as high as possible.
Unscrew the lubricant level control plug. Clean the inside of the box thoroughly. Also clean the unattached magnet located in it.
Wait until the gearbox oil stops flowing. Put the tray back. It must be installed with a new gasket. There is no need to tighten the control plug.
After this, you can pour in new fluid. To do this, you will need to twist the breather at the top of it. Unscrew the cap from the breather. You can remove it with a key number 19.
Place a funnel in the breather. Start pouring liquid until it comes out of the plug hole. After this, screw on the control plug. As a result, you should be filled with 1.5 liters of lubricant.
If in order to remove the fluid completely, you had to lift the wheel from the front, then after you close the plug, you will need to add lubricant to the required volume.
Replace the breather. That's it, the job is finished!

As you can see, there are no difficulties in changing the gearbox oil on a Daewoo Nexia. If you are a beginner, then a video that can be found on the Internet will help you. After changing the lubricant, you will need to make sure that the gear shifts easily at any time of the year. With some effort and spending a small amount of time, any motorist can replace the “consumables” in his car.

Daewoo Nexia is a car from a manufacturer from Korea. It is very popular both in the Russian Federation and in other countries of the former USSR. This is due to the low cost, good performance indicators, and long service life of the vehicle.

How much do you need to fill?

It is equally important for owners of these car models to know how many liters are poured into the transmission. Service books for cars that require replacement of this consumable usually contain a table with fill parameters. In the case of an 8- or 16-valve Nexia, there is no such information in the service manual. However, before changing, you need to consider how much lubricant to pour into the gearbox.

As for volume, the transmission of the Daewoo Nexia should contain about 1.8 liters of oil.

Engine	L.S.	Years of manufacture	Oil volume in manual transmission	Automatic transmission oil volume
1,5	75	1995-2008	1.8 l	3.5 l
1.5i 16V DOHC	85/90	2002-2008	1.8 l	3.5 l
1,6	109	2008	2 l	3.5 l

Transmission "Daewoo"

The following transmissions were installed in Daewoo Nexia:

five-speed manual;
four-speed automatic.

The production of Nexia, equipped with a manual transmission, began in Uzbekistan. What kind of oil is used in this car? SAE 80W90, SAE 75W90 lubricant is used. Only hatchbacks that were produced in 1994-1997 are equipped with automation. Only Dextron 2 is filled into automatic transmissions.

It is worth noting that, in accordance with the recommendations of the Korean manufacturer, there is no need to change the Nexia gearbox oil. Its resource should be sufficient for the entire period of operation. This is approximately two hundred thousand kilometers. It is sometimes necessary to check its quantity and, if necessary, top up.

Changing the oil in the Nexia gearbox is intended only for regions where the temperature is very low (less than thirty degrees). This is due to the fact that in low temperature conditions mineral motor oil thickens. When making a car, mineral water is poured into it to save money. In view of this, it is recommended to change the mineral oil in the Nexia gearbox to synthetic/semi-synthetic before the car has driven one hundred thousand kilometers.

You need to know how to check how many liters of gear oil are in the unit. It is recommended to check it every 8-16 thousand kilometers.

The oil in the gearbox must be poured with the same oil that is already filled.

What oil do you recommend to put in the gearbox?

The description for the car says: The gearbox oil does not require replacement for the entire service life of the gearbox. If necessary, ensure that the oil level is at the bottom edge of the filler plug. I have a 2004 car, mileage 17,700 km, I’m only going to check the oil level in the gearbox in the spring, top it up if necessary, but I’m not going to change it! If the factory instructions say so, then it’s not just a paper of morality!!!
