The 2010 Nissan Murano is designed to use Nissan Genuine Long Life Antifreeze/Coolant (LLC), a 50/50 ethylene glycol solution formulated for Nissan engines. Use Nissan LLC or a coolant that explicitly meets Nissan’s LLC specification, and always mix with distilled water if you’re using concentrate. Do not mix incompatible coolants, and consult the owner’s manual or a dealer if you’re unsure.
Which antifreeze should you use in a Murano?
When selecting coolant, look for the Nissan Long Life Antifreeze/Coolant specification on the label and ensure the product is suitable for aluminum engines used in the Murano. Below are the common options and what to watch for on the label.
- Nissan Genuine Long Life Antifreeze/Coolant (LLC) – Ethylene glycol-based coolant designed for Nissan engines; typically sold as a 50/50 premixed solution with distilled water.
- Universal HOAT/OAT coolant that explicitly states compatibility with Nissan Long Life Coolant or Nissan vehicles – ensure the product lists Nissan LLC compatibility and follow its mixing instructions (premixed or concentrate to be diluted with distilled water).
For simplest, safest service, sticking with Nissan Genuine LLC is recommended. If you use a substitute, verify compatibility on the label and follow the manufacturer’s mixing directions exactly.
Maintenance and replacement tips
Below is a standard approach for draining, flushing, and refilling the Murano’s cooling system. This guide helps ensure you’re using the correct coolant and maintaining proper system pressure and air bleeding.
- Ensure the engine is completely cool and position the vehicle on a level surface with a drain pan underneath.
- Open the radiator drain plug and allow the old coolant to drain completely.
- Optionally flush the cooling system to remove residue, then close the drain plug.
- Fill the system with the appropriate coolant mix (generally 50/50 Nissan LLC; use distilled water if you’re working with concentrate).
- Start the engine with the radiator cap removed and the heater set to hot to bleed air from the system; recheck and top off as needed.
- Inspect for leaks and recheck the coolant level after the engine has cooled for a period of time.
Always use distilled water to dilute concentrates if you’re not using premixed coolant, and avoid mixing coolants with different chemistries. If you’re not comfortable performing a drain/flush, a professional service can ensure proper bleeding and avoiding air pockets.
Bleeding the cooling system
Bleeding is important to remove air pockets that can lead to overheating. After the fill, run the engine with the expansion cap off (careful for hot coolant) until the thermostat opens and the coolant level stabilizes, then replace the cap and perform a final level check once the engine has cooled.
Summary
In short, a 2010 Nissan Murano uses Nissan Genuine Long Life Antifreeze/Coolant (LLC), typically as a 50/50 premixed ethylene glycol solution. Use Nissan LLC or any coolant explicitly labeled as compatible with Nissan LLC, and follow the manufacturer’s mixing and replacement guidance. Properly bleeding and maintaining the cooling system helps prevent overheating and corrosion, keeping the Murano’s engine running smoothly.
