Gartz G11 – Conventional Coolant

Gartz G11 – Conventional Coolant for Engines and Traditional Systems

Gartz G11 is a conventional coolant based on IAT (Inorganic Acid Technology), using silicate additives to provide immediate protection.

It is designed for:

• older vehicles
• copper/brass radiators
• traditional engine systems

Signs of degraded coolant

Common symptoms include:

• discolored coolant
• deposit formation
• overheating
• cooling fan running continuously

Why G11 degrades faster

G11 coolant contains silicate additives that:

• provide fast protection
• but deplete faster over time

Typical service life:

• 2–3 years or ~60,000 km

Applications of Gartz G11

Suitable for:

• older vehicles
• traditional cooling systems
• light-duty trucks
• legacy engine designs

Key performance characteristics

G11 coolant provides:

• immediate corrosion protection
• compatibility with older materials
• fast protective coating

However:

• shorter lifespan
• higher risk of deposits over time

Proper usage recommendations

To maintain cooling performance:

• replace coolant every 30,000 – 50,000 km
• avoid mixing with OAT coolants
• do not use plain water

Gartz expert insight

Mixing G11 with modern coolant types can cause:

• sludge formation
• blockage
• overheating

Using the correct coolant type is critical for system longevity.

Conclusion

Gartz G11 is a practical solution for older vehicles and traditional cooling systems.

It ensures:

• reliable protection
• cost-effective maintenance
• system compatibility
