• ✅ Protection up to -35°C – effective operation of the cooling system even in extreme winter conditions.
• ✅ Compatible with aluminum and steel elements – prevents corrosion, scale formation and rust formation.
• ✅ Stable G11 formula – traditional silicate fluid recommended for older engine types and copper radiators.
• ✅ Extended engine life – protects pumps, seals, radiators and hoses.
• ✅ Color: blue-green – makes it easier to recognize and control the level in the tank.
• ✅ Safe for the environment – does not contain phosphates, amines and nitrites.

Application

STAPAR G11 fluid is perfect for:

• passenger cars, vans and trucks,
• agricultural and construction machinery,
• motorcycles and garden equipment with liquid cooling.

The product can be used in most cooling systems requiring G11 class fluids (compliant with VW TL 774 C / MB 325.0 / MAN 324 Typ NF standards).

⚙️ How does STAPAR G11 fluid work?

The ethylene glycol-based formula lowers the pour point and raises the boiling point of the coolant, providing stable engine cooling in all conditions . Anti-corrosion and anti-sludge additives create a thin protective layer on the system walls, preventing metal wear and microcracks.

FAQ – Blue coolant G11 –35°C 5L STAPAR

1. What is the G11 –35°C STAPAR coolant used for?

G11 coolant is used to cool and protect the cooling system of gasoline and diesel vehicles. It prevents engine overheating, protects against corrosion and deposits, and protects the system from freezing down to -35°C.

2. Is G11 -35°C fluid suitable for every car?

G11 fluid is suitable for older and newer cars that specify G11 fluid in the manufacturer's specifications (typically cars manufactured before 2008–2010).
Not recommended for cars requiring G12, G12+, G12++ or G13.

3. Can G11 be mixed with other coolants?

• Can be mixed with other G11 fluids (silicate-based).

• Mixing with G12/G12+ fluids (based on organic acids) is not recommended as this may impair the protective properties and lead to the formation of deposits.

4. What freezing point does STAPAR G11 fluid provide?

The fluid offers full protection against freezing down to -35°C , which is fully sufficient for Polish winter conditions.

5. Is this liquid ready to use?

Yes. The blue G11 STAPAR 5L liquid is ready to use – it does not need to be diluted with water.

6. How often should the G11 coolant be changed?

Most manufacturers recommend changing the G11 fluid every 2-3 years or 50,000-60,000 km .
It is worth checking the exact recommendations for a specific car model.

7. Does the fluid protect the cooling system against corrosion?

Yes. G11 STAPAR fluid contains anti-corrosion additives that protect:

• water pumps,

• radiator,

• engine block,

• cables and metal components of the system.

8. Can it be used in aluminum radiators?

Yes – G11 STAPAR fluid is safe for aluminum, copper and brass radiators.

9. What should I do if there is a different fluid in the system?

If you are unsure what fluid is in the system, it is recommended to:

1. Flushing the cooling system.

2. Pouring new G11 fluid.

This way you will avoid the risk of sediment formation or chemical incompatibility.

10. Can I refill the system with water?

Only in an emergency. Water will lower the freezing point and reduce its anti-corrosion properties.
For longer use , refill only with G11 -35°C fluid .

11. How to store coolant?

• at a temperature of 5–25°C,

• tightly closed,

• away from children,

• in a cool and dry place.

12. How do I check if G11 fluid is suitable for my car?

Check your vehicle's manual or service sticker. If it says G11 , STAPAR 5L -35°C is the right choice.

13. Is STAPAR fluid safe for the water pump?

Yes – lubrication and anti-corrosion additives extend the life of the water pump and protect its seals.

14. What does a temperature of -35°C do?

This means that the fluid remains fluid even in extreme cold, ensuring that the cooling system functions properly and is not damaged.

15. Can the fluid "wear out"?

Yes. Over time, it loses its anti-corrosion and protective properties. Changing it every 2-3 years is necessary to protect the engine.
