In most Murano models, you should use Nissan Genuine Long Life Coolant (LLC) that meets Nissan specifications, typically a 50/50 premixed solution or a concentrate that is diluted with distilled water. Always verify the exact specification in your owner's manual or with a Nissan dealer.
The Murano’s cooling system relies on a long-life coolant designed to resist corrosion and maintain effective heat transfer. While formulations can vary by model year, the safest approach is to use Nissan LLC or an equivalent coolant that explicitly states compatibility with Nissan Long Life Coolant. The following guidance covers what to use and how to replace or top off coolant correctly.
Choosing the right coolant for your Murano
Before selecting coolant, understand the available options and how to use them properly. The goal is to maintain the factory-standard protection for the cooling system and engine materials.
- Nissan Genuine Long Life Coolant (LLC) premixed 50/50: ready to pour into the reservoir and a common choice for most Murano owners.
- Nissan Genuine Long Life Coolant Concentrate: must be diluted with distilled water to achieve a 50/50 mix before use, following the label’s instructions.
- Approved non-Nissan coolants that clearly meet Nissan specifications: if you cannot obtain Nissan LLC, you may use a high-quality coolant that explicitly states compatibility with Nissan Long Life Coolant, but verify with a dealer or service manual before using.
Whichever option you choose, ensure the coolant meets Nissan’s specification and is used at the correct 50/50 dilution (if concentrated). Do not mix different coolant chemistries unless you have verified compatibility with Nissan’s guidelines, as improper mixtures can cause corrosion or deposits in the cooling system.
How to fill, bleed, and maintain the Murano cooling system
When replacing or topping off coolant, follow proper steps to prevent air locks and overheating. The procedure below is a general guide; consult your owner's manual for model-specific instructions.
- Ensure the engine is completely cool before opening any caps to avoid scalding or pressure release hazards.
- If performing a flush, place a drain pan under the vehicle and drain the old coolant according to local disposal regulations.
- If using concentrate coolant, mix it with distilled water to a 50/50 ratio as directed on the product label.
- Pour the prepared coolant into the reservoir slowly, stopping at the recommended level on the reservoir’s markings.
- Run the engine with the heater set to hot to circulate coolant and help bleed air from the system; monitor for leaks and watch the level in the reservoir.
- After the engine reaches operating temperature and the initial bleed is complete, re-check and top off the coolant if necessary.
- Inspect hoses and clamps for signs of wear or leaks and recheck the level after a day or two of driving.
Concluding: Properly filled and bled coolant helps maintain consistent operating temperatures and protects the cooling system from corrosion. Monitor levels and signs of leaks after service.
Frequently asked questions about Murano coolant
Can I mix different brands of coolant?
Mixing different brands or chemistries is not recommended unless both products explicitly state compatibility with Nissan Long Life Coolant. If you’ve mixed something inappropriate, flush the system and refill with the correct Nissan LLC or an approved Nissan-specified coolant.
Is coolant color a reliable indicator of compatibility?
No. Colors can vary between manufacturers and batches, so always verify that the coolant meets Nissan’s specifications rather than relying on color alone.
Summary
For a Nissan Murano, use Nissan Genuine Long Life Coolant that meets Nissan specifications, typically a 50/50 premixed solution or a concentrate diluted to 50/50. Follow the owner’s manual for exact part numbers and procedures. If you’re unsure, consult a Nissan dealer or qualified technician. Proper coolant selection and maintenance protect the engine and cooling system over the vehicle’s life.
