Caleb Wilson asked 4 months ago
I own a 21 Nissan Rogue with around 20,000 miles on it. It's been about 1.5 years since I've serviced the car, particularly for the coolant system. Recently, I noticed that the coolant level is slightly below the minimum line. I've never added coolant myself, nor has the dealership topped it off during this period. Is this drop in coolant level normal for a car that hasn't been serviced in a year and a half? Your guidance would be greatly appreciated. Thanks!

Hello there, Caleb! Great question! Monitoring the coolant level in your car is indeed important for maintaining engine health. Here’s some advice tailored to your situation, from what I can tell based on your descriptions:
  1. Normal Coolant Levels: It's not unusual for coolant levels to fluctuate slightly over time due to factors like evaporation or minor system seepage. However, a noticeable drop below the minimum line, especially in a relatively new car like your 2021 Nissan Rogue, warrants attention.
  2. Checking for Leaks: Cars shouldn't regularly lose coolant. If you're having to add coolant frequently, it's likely due to a leak. Inspect hoses, the radiator, and connections for signs of leakage.
  3. Coolant Top-Up: For now, you can top up the coolant to the appropriate level. If you're in a region without harsh winter temperatures, using distilled water is a temporary solution. However, if you're approaching colder months, it's better to use the appropriate coolant mixture to maintain the correct freezing point.
  4. Service and Maintenance: Given your car's age and mileage, it's a good idea to adhere to the manufacturer's recommended service schedule. While coolant doesn't typically need frequent topping up, it should be replaced according to the schedule to ensure optimal performance and longevity of the engine.
  5. Monitoring After Top-Up: After topping up, keep an eye on the coolant level. If it continues to drop, it's crucial to have your car checked by a professional to diagnose any potential issues like leaks or cooling system problems.
  6. Importance of Regular Checks: Regular checks of all fluid levels, including coolant, are vital. These checks can prevent more significant issues down the line and ensure your vehicle runs smoothly.
