The 2019 Nissan Sentra uses Nissan DEX-COOL long-life coolant (orange), typically supplied as a pre-mixed 50/50 blend with water. This is the recommended coolant for this model.
In more detail, DEX-COOL is Nissan’s orange, silicate-free coolant designed for long life in Nissan engines. Use only DEX-COOL or an approved Nissan-compatible equivalent, and avoid mixing with green or other coolant types. Always refer to the owner’s manual for exact fill capacity and replacement intervals, as these can vary by market and engine configuration.
Recommended coolant for a 2019 Sentra
Key facts to know before purchasing or adding coolant:
- Nissan DEX-COOL long-life antifreeze/coolant, orange in color.
- In the U.S. and many markets, it is commonly sold pre-diluted as a 50/50 mix with water; in some regions you may buy the concentrate and mix it per label.
- Do not mix DEX-COOL with green or other traditional coolants; mixing can reduce protection and cause deposits.
- Use only DEX-COOL or an approved Nissan-compatible equivalent; when in doubt, check the owner's manual or consult a Nissan dealer.
- Keep the system within the recommended reservoir levels and avoid topping up with incompatible fluids.
Following these guidelines helps maintain cooling system performance, prevent corrosion, and support engine longevity.
Safe handling, topping off, and replacement steps
If you’re planning to top off or perform a coolant flush/replacement, follow these steps:
- Park on level ground and let the engine cool completely before opening the cooling system pressure cap or reservoir.
- Inspect the coolant color and labeling to confirm it is DEX-COOL (orange) before adding or replacing any coolant.
- For topping off, add DEX-COOL until the reservoir reaches the MAX fill line, then recheck after a short drive and cooling cycle.
- For a full flush/replacement, drain the old coolant from the radiator and engine block (as specified by the service manual), flush with distilled water if required, and refill with a 50/50 DEX-COOL mixture.
- Dispose of used coolant responsibly at an authorized collection/disposal facility; never pour it down a drain or onto the ground.
Always verify the correct procedure for your market and engine variant, and consult a qualified technician if you are unsure about flushing or replacing the cooling system.
Summary
The 2019 Nissan Sentra relies on Nissan DEX-COOL long-life coolant, an orange, silicate-free antifreeze designed for Nissan engines. Use the DEX-COOL coolant or an approved equivalent, prefer the pre-mixed 50/50 version where available, and avoid mixing with other coolant types. Follow the owner’s manual for capacity, maintenance intervals, and replacement procedures, and seek professional help if you’re unsure about service steps.
