YANMAR YG30R Ultralife ELC Antifreeze Coolant 1 Gal Red — 50/50 Pre-Diluted Nitrite-Free Extended-Life

YANMAR YG30R Ultralife ELC is a factory-grade, 50/50 pre-diluted red coolant engineered for Yanmar equipment that offers nitrite-free extended life protection and includes a bittering agent for safety.

This product is the original-equipment coolant specified by YANMAR (OEM part YG30R). It arrives ready to use—no mixing required—and is formulated to provide corrosion and freeze protection appropriate for engines and cooling systems designed for extended-life, nitrite-free coolants. The red formula helps technicians and owners quickly identify the correct fluid during service.

What makes this coolant different from generic antifreeze?

YG30R is a manufacturer-recommended formula developed to meet YANMAR's performance needs and material compatibility. Unlike generic concentrates, this one is factory pre-diluted 50/50 for immediate use and is nitrite-free to suit systems requiring extended-life chemistry.

• OEM YANMAR part number YG30R ensures exact specification match
• Pre-mixed 50/50 concentration—no on-site dilution
• Nitrite-free extended life chemistry for compatible cooling systems
• Distinct red color for quick identification

How do I use this coolant safely and correctly?

Drain and flush the cooling system per your equipment manual before adding this coolant to avoid contamination. Because it’s pre-diluted, pour directly into the radiator or coolant reservoir and top to the fill mark; follow torque and bleed procedures recommended by YANMAR.

• Refer to the original equipment owner's manual for compatibility and service intervals
• Use as supplied—no additional water needed
• Dispose of old coolant according to local regulations
• Contains a bittering agent to discourage ingestion—store securely

What protective performance can I expect in equipment service?

This coolant provides corrosion inhibition and freeze/boil protection consistent with YANMAR’s extended-life specifications. It’s formulated to protect engine metals and cooling system components when used as directed in compatible YANMAR machinery.

• Engineered for metal compatibility in YANMAR cooling systems
• Helps prevent scale, rust, and electrochemical degradation
• Stable pre-mix reduces error from improper dilution
• Extended-life formulation lowers frequency of full coolant changeouts when maintained properly

Can I mix this with other coolant brands or types?

Mixing different coolant chemistries risks reducing effectiveness and may harm system components. Only mix with products explicitly labelled compatible with nitrite-free, extended-life red coolants; when in doubt, perform a full system flush and refill with YANMAR YG30R.

• Avoid mixing unless compatibility is confirmed by the manufacturer
• Flushing the system prevents cross-contamination and ensures performance
• Use identical YG30R replacements for consistent chemistry

Who is this for: YANMAR YG30R Ultralife ELC is intended for owners, technicians, and fleet managers of YANMAR engines and equipment that require OEM-specified, nitrite-free extended-life coolant. It’s ideal for service shops, agricultural, marine, and industrial operations seeking a ready-to-use, manufacturer-approved coolant in a 1-gallon size.
