The Infiniti Q30 uses Nissan/Infiniti Long-Life Antifreeze/Coolant Type 2 (LLC Type 2), an ethylene glycol-based coolant typically sold premixed in a 50/50 ratio with distilled water. Use Genuine Nissan/Infiniti coolant or an approved equivalent that explicitly lists compatibility with Nissan/Infiniti Type 2.
In practice, selecting the correct coolant matters for protecting the cooling system against corrosion and for maintaining proper freeze/ boil protection. Always refer to the owner's manual or consult a dealer or qualified mechanical professional if you’re unsure about the exact specification or service intervals.
Which coolant should you use on a Q30?
To ensure compatibility with the Q30’s cooling system and aluminum components, only coolant meeting Nissan/Infiniti Type 2 specifications should be used. The quick guidance below helps you identify appropriate options:
- Genuine Nissan/Infiniti Long-Life Antifreeze/Coolant Type 2, or an approved equivalent that explicitly lists compatibility with Nissan/Infiniti Type 2.
- Ethylene glycol-based coolant designed for long-life service.
- Most consumer products are sold premixed 50/50 with distilled water; verify the label to confirm this mix.
- Do not mix with coolant types not specified as compatible with Nissan/Infiniti Type 2 without professional guidance.
- Color alone is not a reliable indicator of compatibility; always confirm the specification on the product.
In short, stick to the official Type 2 long-life coolant for the Infiniti Q30 and avoid generic brands that do not specify compatibility with Nissan/Infiniti Type 2.
Top-up and replacement tips
If you need to top up or replace the coolant, follow these general steps while the engine is cool:
- Open the coolant reservoir cap slowly and check the level against the Min/Max marks.
- If the level is low, add the correct 50/50 premixed Nissan/Infiniti Type 2 coolant up to the fill line.
- For a full drain and fill, flush the cooling system if recommended by the service manual, then refill with the same Type 2 coolant.
- Bleed the cooling system if required to remove air pockets, following the vehicle’s service procedure.
- Dispose of old coolant responsibly and in accordance with local regulations.
If you’re unsure about the procedure or compatibility, have a professional perform the service to ensure the cooling system remains free of air pockets and properly protected against corrosion.
