The Nissan Maxima generally requires Nissan Genuine Long Life Coolant (LLC) Type 2, a HOAT ethylene glycol coolant. It is typically supplied as a 50/50 premixed solution or as concentrate to be diluted with distilled water. Always use coolant that meets Nissan’s Type 2 specification and confirm with your owner's manual or a dealer for your exact year and market.
Coolant specification for most Maxima models
Understanding the official coolant specification helps ensure the cooling system stays protected against corrosion and overheating. Nissan’s modern vehicles, including the Maxima, are designed around their own Long Life Coolant formulation, commonly referred to as Type 2. This coolant is formulated to meet Nissan engine materials and cooling system tolerances and is typically HOAT-based.
- Nissan Genuine Long Life Coolant Type 2 (LLC Type 2): The recommended coolant for most current Maxima models. It is available as premixed 50/50 and as concentrate that must be diluted with distilled water to the same 50/50 ratio.
- Non‑Nissan brands: Only use an approved equivalent that explicitly meets Nissan Type 2 specifications. Do not use Dex-Cool (GM) or other brands unless they are certified to meet Nissan Type 2 requirements.
- Color and labeling: Coolant color can vary by batch and market. Do not rely on color alone to determine compatibility; always verify the part specification matches Nissan Type 2.
- Mixing and compatibility: If you buy concentrate, mix with distilled water to achieve a 50/50 solution. Do not mix different coolant chemistries unless the product explicitly states compatibility with Nissan Type 2.
In short, the safest and most reliable choice is Nissan Genuine Long Life Coolant Type 2, used according to the label instructions and your vehicle’s year-specific guidance.
Maintenance and replacement guidance
Maintaining the correct coolant type and mixture helps protect the cooling system from corrosion and overheating. Here are general guidelines to follow, while always consulting your owner’s manual for year-specific intervals.
- Check the coolant level when the engine is cold. The reservoir should read between the "MIN" and "MAX" marks.
- If topping up, add 50/50 Nissan LLC Type 2 coolant until the level is within the recommended range.
- If you suspect a leak or the coolant looks contaminated, have the system pressure-tested and flushed by a qualified technician.
- When replacing coolant, drain the old coolant, flush if needed, and refill with 50/50 Nissan LLC Type 2 solution. Run the engine to operating temperature, then recheck levels and top up as necessary.
- Dispose of old coolant properly and never mix different coolant chemistries without explicit compatibility guidance.
For model-year-specific requirements, always refer to the Nissan owner's manual or contact a Nissan dealer or certified mechanic. They can confirm whether your particular Maxima requires Type 2 coolant and the exact mixing ratio for your locale.
Summary
Most Nissan Maxima models take Nissan Genuine Long Life Coolant Type 2, a HOAT ethylene glycol coolant. Use either premixed 50/50 or concentrate diluted to 50/50 with distilled water, and avoid non‑approved universal formulas. Always verify the exact specification for your year and market in the owner's manual or with a dealer, and follow proper maintenance procedures to keep the cooling system performing reliably.
