Overview
MOTUL AUTO COOL EXPERT -37°C is a long-life, ready-to-use coolant based on Mono Ethylene Glycol (MEG), using hybrid organic and inorganic inhibitors known as "Hybrid Tech." It can be mixed with all Mono Ethylene Glycol-based coolants and is recommended for the cooling systems of passenger cars, heavy vehicles, construction and agricultural vehicles, gardening equipment, boats and stationary engines — particularly for VAG group (Volkswagen, Audi, Skoda, Seat) cooling circuits requiring a coolant meeting the VW G12 EVO (VW TL 774 L) specification.
Compatibility
Compatibility information not available.
Key Features
- Contains a bittering agent to help prevent ingestion, since coolants/antifreeze have a naturally sweet taste but are harmful if swallowed
- Protects the cooling system against water freezing and metal parts against corrosion
- Hybrid Tech (Si-P-OAT: Silicates, Phosphates and Organic Acids synergy) promotes heat transfer, improves cooling capacity, gives higher thermal stability and more efficient engine operation, with stable anticorrosive protection maintained over long periods of use
- Neutral action on gaskets, hoses, pipes and plastic components
- Meets the latest VW G12 EVO (VW TL 774 L) specification and is compatible/miscible with coolants meeting all previous VW specs: G11 (TL 774 C), G12 (TL 774 D), G12+ (TL 774 F), G12++ (TL 774 G), G13 (TL 774 J)
Applications
- Cooling systems of passenger cars, heavy vehicles, construction and agricultural vehicles, gardening equipment, boats, stationary engines
- VAG group (Volkswagen, Audi, Skoda, Seat) vehicles requiring VW G12 EVO (TL 774 L) or compatible legacy G11-G13 specification coolant
