Checking the level and topping up the engine cooling liquid Opel Astra II G (Classic) 1998 - 2009

Parts and consumables:

• rags
• Funnel (if needed)
• Coolant GENERAL MOTORS DEX-COOL LONGLIFE - 93170402

Notes:

Checking the coolant level in the expansion tank of the cooling system should be carried out at each inspection of the car before driving and always in case of engine overheating and the associated release of fluid from the system. Its sharp decrease or increase should be a signal for an immediate check of the engine cooling system. 

Use only the correct mixture of ethylene glycol and distilled water (approximately 50/50) to correct the fluid level. Remember that the frequent use of plain water for this purpose leads to a gradual dilution of the antifreeze and the loss of frost resistance and anti-corrosion properties of the mixture. You should also not abuse various types of additives.

Do not mix liquids of different colors and different manufacturers. If you do not know the brand of the liquid filled in, and the liquid needs to be topped up, then a complete replacement of the Opel Astra G antifreeze  in the cooling system is necessary.

Only use products from trusted manufacturers. Remember that the use of poor quality coolant leads to costly engine repairs.

The coolant is toxic, so be careful when handling it.

Check the coolant level of the Opel Astra G  only on a cold engine. 

1.  Park the vehicle on level ground, allow the engine to cool, and  open the hood.  The coolant expansion tank is located on the left side of the engine compartment in the direction of the vehicle.

2.  Visually check the Opel Astra G  coolant level in the reservoir. With a cold engine, it should be slightly above the  KALT / COLD mark on the expansion tank of the Opel Astra G. 

3.  If the liquid level has dropped below the  KALT/COLD mark , then it is necessary to add coolant. 

4. To top up the coolant, turn it counterclockwise and remove the cap from the reservoir.

Warning:

In no case do not remove the cap from the filler neck of the expansion tank when the engine is hot!

5.  Add coolant to the required level.

Warning:

Do not fill the fluid reservoir  above the KALT/COLD mark as the fluid volume increases when the engine is running. When starting the engine, the expansion tank cap must be closed.

Coolant that has fallen on engine parts or paintwork must be removed with a rag.

6.  Close the coolant expansion tank cap tightly. Remove spilled liquid with a rag.

Warning:

When the engine is running, the expansion tank is under pressure, so coolant may leak from under a loosely wrapped plug or the plug may be torn off.

Notes:

If the coolant that you just filled in suddenly suddenly turned brown quickly, it means that you were sold a fake, in which they "forgot" to add corrosion inhibitors. Change the fluid as soon as possible before it has had time to corrode the cooling system.

If the coolant level in the expansion tank is constantly decreasing, then the engine cooling system is most likely leaking, so it is very important to immediately check its tightness and repair the malfunction.

Do not allow antifreeze to come into contact with exposed areas of the body and painted surfaces of the car. Accidental splashes should be washed off immediately with plenty of water. Remember that  Opel Astra G antifreeze  is a highly toxic liquid and getting it into the body, even in small quantities, is fraught with the most serious consequences (up to death).

Never leave antifreeze stored in a loosely sealed container and clean up spilled coolant on the floor without delay. Remember that the sweet smell of antifreeze can attract the attention of children and animals.

Never drain old coolant down the drain and onto the ground!
