The Murano generally uses Nissan Long Life Antifreeze/Coolant (LLC), a HOAT ethylene glycol-based formula, typically sold as Nissan Genuine Long Life Coolant and usually provided pre-mixed 50/50 with water.
What your specific Murano needs can vary by model year and engine, so consult your owner’s manual or a Nissan dealer for the exact specification. In practice, LLC formulations are standard across most Murano models built in recent decades.
Recommended coolant type for Nissan Murano
To keep the cooling system protected and operating correctly, use only a coolant that meets Nissan’s LLC specification. This is designed for Nissan aluminum engines and cooling-system components and is typically sold as Nissan Genuine Long Life Coolant or an equivalent labeled to meet Nissan LLC requirements.
- Nissan Genuine Long Life Coolant (LLC) or another coolant that explicitly meets Nissan LLC specifications. This is the safest choice for compatibility and warranty considerations.
- Ethylene glycol-based HOAT coolant formulated to the LLC standard. Do not substitute with coolants that are not labeled for Nissan LLC, as mismatched inhibitors can cause corrosion or deposits.
- Most Murano models use a pre-diluted 50/50 mix (coolant to water). If you buy concentrate, mix it to the 50/50 ratio with distilled or demineralized water as directed on the product label.
- Avoid coolants not approved by Nissan for LLC. Mixing incompatible chemistries can lead to cooling-system problems and potential warranty issues.
Conclusion: Sticking to Nissan-approved LLC coolant ensures proper protection for the cooling system, especially in aluminum components and heat-exchanger regions.
Choosing the right coolant and how to verify
Verifying compatibility is important if you’re buying coolant from a parts store or online. Look for explicit labeling that the product meets Nissan Long Life Coolant specifications and is suitable for your Murano’s year and engine.
- Always check the product label for “Nissan Long Life Coolant” or LLC compatibility with Nissan specifications.
- When in doubt, ask a parts counter associate or your dealer to confirm the exact LLC specification matches your model year.
- Follow the dilution recommendations on the bottle; if purchasing concentrate, use distilled water to achieve the 50/50 mix.
- Do not mix LLC with non-compatible coolants unless the product explicitly states it is compatible with Nissan LLC; otherwise, flush the system before refilling.
Conclusion: Correct verification helps avoid incorrect inhibitor chemistry that can lead to corrosion, deposits, or reduced cooling performance.
Maintenance tips and service intervals
Regular checks and follow-up service are essential for maintaining your Murano’s cooling system. Adhere to the maintenance schedule in your owner’s manual and use the LLC coolant specified by Nissan.
- Check coolant level when the engine is cold and topped up with the same LLC type; never mix different coolant types in the system.
- Have the coolant system flushed and refilled with LLC at the interval recommended by Nissan for your model/year, or sooner if you notice overheating, leaks, or a drop in coolant level.
- Use distilled or demineralized water if you’re preparing a 50/50 mix from concentrate to prevent mineral buildup.
- Inspect hoses, clamps, and the radiator cap during routine maintenance for signs of wear or leakage.
Conclusion: Following the manufacturer’s maintenance guidance helps ensure long-term reliability and prevents cooling-system problems that can arise from incorrect coolant use or aging fluid.
What to do if you can’t find Nissan LLC coolant
If a Nissan LLC product isn’t readily available, contact a Nissan dealership or trusted auto parts retailer to confirm an equivalent that meets Nissan LLC specifications. Some reputable brands offer coolant formulated to be compatible with Nissan LLC; ensure the product clearly states compatibility with Nissan Long Life Coolant and your Murano’s year.
- Ask for a coolant that explicitly meets Nissan LLC requirements and is recommended by Nissan for your model year.
- Provide the service advisor with your Murano’s year, engine, and whether the system has ever been flushed or replaced.
- Never use a coolant labeled for other manufacturers unless it clearly states compatibility with Nissan LLC; if in doubt, have the system flushed and refilled with LLC at a shop.
Conclusion: When LLC isn’t available locally, seek official or dealership-approved equivalents to avoid compatibility issues and protect the cooling system.
Summary
The Nissan Murano typically calls for Nissan Long Life Antifreeze/Coolant (LLC), a HOAT, ethylene glycol-based formula, usually pre-mixed 50/50. Use Nissan Genuine LLC or an equivalent that explicitly meets Nissan LLC specifications, and follow the owner’s manual for maintenance intervals and replacement. If you can’t source LLC locally, consult a Nissan dealer to obtain an approved equivalent and have the system serviced accordingly. Regular checks and proper dilution help protect the engine and cooling system over the life of the vehicle.
