Changing the oil in the gearbox of the popular Opel Astra H car is a very popular procedure that is quite feasible with self-service. In addition, the possibility of carrying it out on their own has long been appreciated by the owners of supported Astra H models, who, in fact, do not need expensive repairs in the absence of a warranty. In this article, we will consider in detail how to replace gear oil in an Opel Astra H manual transmission.

The manufacturer claims that the factory grease in the Opel Astra H box is designed for the entire life of the car. Whether this is so depends on climatic and road factors. In Russia, for example, it is necessary to regularly monitor the level, as well as the state of the quality of the liquid. Very often, the oil has to be changed after 30 thousand kilometers, or even earlier.

What kind of oil to fill

Opel has set the following oil parameters suitable for the Opel Astra H transmission:

• API Standard: GL4
• SAE: 80W-90 and 75W-90

Checking the oil level

Before making sure that a fluid change is necessary, you first need to check the level of remaining lubricant. For this procedure, you will need socket wrenches for 13 and 17. In addition, you must have a syringe for filling the transmission fluid - if you still need a regular topping up, and not a complete replacement. So, the procedure for checking the oil is as follows:

1. The car is installed on a flyover or lift. In extreme cases, a jack will do.
2. Go under the car and find the gearbox housing located on the side of the checkpoint. There is a control hole in the crankcase, which is tightly closed with a stopper. If small oil smudges are visible near the hole, then the oil level is normal and nothing needs to be filled. If no traces of oil are found, and the edges of the drain hole are completely dry, then you will need to add oil. In addition, there is only sense in a regular bay if the current oil level is clean enough, and also devoid of any mud deposits and metal chips. Chips and dirt usually appear at high mileage, and then a complete oil change may be necessary, along with draining the old oil.
3. After making sure that the factory oil is clean enough, unscrew the drain plug and add new fluid until the oil starts to pour out. The liquid is poured using a filling syringe.
4. As soon as the oil began to flow out, at this moment we immediately wrap the drain plug back. This completes the oil filling process successfully.

Procedure for a complete oil change

This procedure is slightly different from the above process, and consists of the following steps:

1. The first step is to prepare materials: a container for draining used oil, a set of tools, including wrenches and heads, as well as rags, a filling syringe, rubber gloves, new gaskets and 2 liter gear oil.
2. Warm up the engine and the oil in the box in advance so that the liquid becomes more fluid. This will speed up the draining process.
3. The machine is mounted on a lift
4. In the upper part of the gearbox housing, the gearbox filler plug is unscrewed
5. In the lower part of the gearbox housing, the gearbox drain plug is unscrewed, the old fluid is drained into a pre-prepared pan. If access to the plug is difficult, then you will have to remove the pan and gasket. The gasket will then need to be replaced with a new element. Sealant can be used instead
6. After draining the used oil, we proceed to the next step - filling in fresh oil. We leave the pit, and using a syringe, fill in new oil. The liquid should appear from the control hole, after which the oil change process in the Opel Astra H manual transmission can be considered successfully completed.
7. Now it remains to tightly tighten all the holes, including the filler plug, then you can take a test drive and measure the fluid level. Within 2-3 weeks, the oil may need to be topped up a little.

Hi all! In this article we will tell you how the oil is changed in the Opel Astra manual transmission. This procedure is very simple, but if you are doing it for the first time, it is better to familiarize yourself with our manual first. So let's go.

The frequency of changing the oil in the manual transmission Opel Astra J (H)

On the Opel Astra J or H, the F17 manual transmission is installed, which is maintenance-free. In other words, the oil in this box does not change and is designed for the entire life of the car. That's what the regulations say. Yes, and you can verify this just by looking at the box itself, on which there is not even a drain plug. However, as experience shows, the oil in any gearbox ages and loses its properties over time. This leads to premature wear of manual transmission parts, which over time threatens either to replace the assembly as a whole or to overhaul it. To avoid all this, it is better, contrary to the instructions of the manufacturer and authorized dealers, to replace the manual transmission fluid. We will describe how this is done below.

What is required for an independent oil change in a manual transmission Opel Astra H (J)?

First you need to decide on the place where the work will be done. A good option would be a garage equipped with a pit. Everything can be done on the overpass. And you can at worst use a jack. The last option is not the most convenient, but it is the place to be if you are not afraid of difficulties. We did all the work in the pit.

Secondly, we will need tools for filling and draining oil from the box. For filling, we used a simple funnel and a thin hose, one end of which was inserted into the filling hole, and a funnel was simply inserted into the other. It turned out a simple funnel extension. All for convenience. To drain mining, we need any convenient container. For example, a basin, a cropped canister, a PET bottle from an anti-freeze or water. Look in the garage. I think there is always something.

Thirdly, we will need tools. This is a 10" ratchet socket and a 19" open end wrench. You will also need a flathead screwdriver.

Fourth, we will need new oil in the box and a differential pan gasket. As for the oil, you will need 1.6 liters of transmission fluid for manual transmission GM 80W article 1940182.

Do-it-yourself oil change in a manual transmission Opel Astra

1. We drive the car into the pit, warm up the engine and turn off. We go down under the car. If an engine protection is installed on the car, then we dismantle it. Then we unscrew the 10 bolts securing the differential pan. Keep a container handy for working off, as oil will pour out.

2. When the oil has stopped flowing, we remove the old gasket and install a new one in its place. We put all the bolts in place and stretch.

3. Open the hood and disconnect the battery. Additionally, you will need to dismantle the battery pad.

4. We will pour oil into the box through the breather. But in order to do this, you need to unscrew it. We take a 19 "key and unscrew the breather. Insert a hose into the hole formed, and a funnel into it and fill in about 1.5-1.6 liters of gear oil.

5. We check the oil level at the control hole. We turn the steering wheel all the way to the left and find the control plug. We turn it out. At this point, oil should flow. When the oil has finished flowing, we wrap the control plug in place.

6. Reinstall the breather and battery pad. We connect the battery.

That's actually all. The oil change in the Opel Astra manual transmission is considered complete at this point. As a result, you will extend the life of the manual transmission, and also get a nice bonus in the form of a reduction in the noise of the box. That's all, thanks for your attention.

Cars belonging to the Opel Astra family are distinguished by their endurance, equipped with power plants that have a long working life. The engine capacity on the Opel Astra H model varies from 1.2 to 2.2 liters, on the Opel Astra J from 1.4 to 2.0 liters. Mechanical and automatic transmissions are found on each of these modifications. Also, Opel Astra H supports the installation of a robotic version.

Transmission oil change procedure

Automatic transmission Opel Astra H does not have a drain hole. To replace the fuel, it is required to remove the liquid through the sump. Especially for this, it is necessary to loosen the fixing bolts. From improvised items you will need: a set of wrenches, a hexagon, empty containers, rags, a syringe with which oil will be added to the manual transmission or other box. In addition to this, a special sealant may be needed (an alternative to a pan gasket).

The position of the control and drain holes

The main stages of changing the oil at the checkpoint in the Opel Astra:

1. The machine warms up to ensure the best fluidity of the fuel.
2. Opel starts up on a flyover to open access to the drain plug, which must be unscrewed.
3. The fill plug is loosened.
4. A container is placed under the pallet, fixed on the fixing bolts, which must be loosened.
5. The pallet is removed from the regular place, the gasket that is present here is removed.
6. The pan must be cleaned, if there is no new gasket, sealant should be applied.
7. The pallet is installed in place.
8. The oil level control plug is unscrewed with a hexagon. Due to this, the old oil drains.
9. Using a filling syringe or a funnel with a hose, new fuel is added.
10. New fuel is added to the level of the filler neck.
11. Open holes are twisted.

At the last stage, the car starts, warms up, the driver must alternately change speeds several times. After that, you again need to check the oil level in the gearbox Opel Astra J, H or another modification. As a rule, it is necessary to add it again.

About 4 liters of new transmission fluid is poured into the gearbox. Changing the oil in a manual transmission may well be carried out independently.

Gearbox Oil Selection

Caring for any transmission option consists in the control of the oil level in the gearbox by the car owner, as it loses its working properties over time. According to the established regulations, this procedure should be carried out every 15,000 km. Changing the oil in the gearbox is relevant if problems in the operation of the gearbox have begun to be noted, for example, difficulties with shifting gears.

Castrol 75 W-80 Liqui Moly

What kind of oil to fill? Whenever the question arises of changing the oil in an Opel Astra in a box, it does not matter which model it is H, J or Astra G, you should opt for the original options. It is recommended to purchase the following transmission fluid options for the Opel Astra gearbox: GL-4 with a viscosity of SAE 75W-90, 80W-90 (Castrol, Liqui Moly). Their distinctive feature is that such fuel will not lose its properties when exposed to high temperatures.

By performing a timely oil change, the owner of the Opel will extend the gearbox life.
