1. Genuine Nissan Coolant: It's always advisable to use genuine Nissan coolant as it's specifically formulated to meet the requirements of Nissan engines and cooling systems. Genuine Nissan coolant provides excellent corrosion protection, heat transfer, and long-term stability.
2. Ethylene Glycol-Based Coolant: Nissan Primera cars typically require ethylene glycol-based coolants. Ethylene glycol is mixed with water in specific proportions (usually 50/50) to provide antifreeze and corrosion protection. Ensure that the coolant you use contains a corrosion inhibitor package suitable for aluminum engines. Some recommended types of ethylene glycol-based coolants include:
a. Extended Life (Long Life) Coolant: These coolants offer extended service intervals (such as 5 years or 100,000 miles) and provide advanced protection against corrosion and deposits. They are often referred to as "long-life" or "extended-life" coolants.
b. Conventional Coolant (Green/Blue): Conventional coolants are more traditional types of ethylene glycol-based coolants. They come in colors like green or blue and typically require frequent replacement (around 2 years or 24,000 miles).
It's essential to avoid mixing different types of coolants unless explicitly recommended by the manufacturer. It can lead to compatibility issues, reduced performance, or harm to the cooling system components. Always follow the prescribed coolant change intervals mentioned in your vehicle's maintenance schedule.
