Coolant G12+

Gartz G12+ – OAT Coolant for Modern Engines and Aluminum Systems

Gartz G12+ is an Organic Acid Technology (OAT) coolant designed for modern cooling systems, especially those using aluminum components.

It meets VW TL 774 D/F standards and is widely used in modern vehicles.

Unlike traditional coolant, G12+:

• does not contain silicates or phosphates
• provides targeted corrosion protection
• reduces deposit formation

Signs of degraded coolant

Common symptoms include:

• discolored coolant
• overheating engine
• cooling fan running continuously
• coolant loss

Causes of cooling system failure

Real-world conditions such as:

• heavy traffic
• high temperatures
• lack of maintenance

cause coolant to:

• oxidize
• lose corrosion protection
• form deposits

This leads to:

• radiator blockage
• reduced cooling efficiency
• overheating risk

Applications of Gartz G12+

Suitable for:

• modern vehicles
• European cars
• aluminum cooling systems

Compatible with brands like:

• Volkswagen, Audi
• BMW, Mercedes
• Toyota, Hyundai

Key performance characteristics

G12+ coolant provides:

• corrosion protection
• long service life
• improved heat transfer

It also:

• increases boiling point
• lowers freezing point
• operates across a wide temperature range

Proper usage recommendations

To maintain cooling performance:

• replace coolant every 40,000 – 80,000 km
• avoid using plain water
• do not mix incompatible coolant types

Gartz G12+ helps:

• stabilize engine temperature
• prevent overheating
• protect the cooling system
• extend engine life

Gartz expert insight

Using incorrect coolant in modern engines can cause:

• corrosion
• sludge formation
• cooling system failure

G12+ is not optional, but essential for modern vehicles.

Conclusion

Gartz G12+ is a critical solution for modern engine protection.

It ensures:

• stable temperature
• long-term reliability
• reduced maintenance costs
