Coolant M77

Gartz M77 – OAT G12+ Coolant for Modern Vehicles

Gartz M77 is an OAT-based (Organic Acid Technology) coolant premixed with distilled water at a 1:1 ratio, meeting OEM standards.

It provides:

• overheating protection
• corrosion resistance
• scale prevention
• long service life

Signs of degraded coolant

Over time, coolant loses its effectiveness.

Common symptoms include:

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

Causes of cooling system inefficiency

Real-world driving conditions:

• heavy traffic
• high temperatures
• lack of maintenance

can cause coolant to:

• oxidize
• lose corrosion protection
• form deposits

This leads to:

• radiator blockage
• reduced cooling efficiency
• engine overheating

Applications of Gartz M77

Compatible with:

• Mercedes-Benz
• BMW, MINI
• Volkswagen G12+
• Toyota, Lexus
• Hyundai, Mazda

Suitable for:

• passenger cars
• European vehicles
• high-performance engines
• light commercial vehicles

Key performance characteristics

OAT coolant technology offers:

• extended service life
• reduced deposits
• improved heat transfer

It also features a high boiling point (~135°C), improving thermal stability.

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 M77 helps:

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

Gartz expert insight

In real garage conditions:

• many vehicles use plain water instead of coolant
• lack of maintenance leads to corrosion

In hot climates and heavy traffic:

• cooling systems are under constant stress

Using proper coolant significantly reduces the risk of overheating and expensive repairs.

Conclusion

Coolant is not just water, but a critical protection system for the engine.

Gartz M77 ensures:

• stable temperature
• corrosion protection
• long-term reliability
