How often should the coolant in a Teana be replaced?

Vehicle coolant generally needs to be replaced every 2 years or 40,000 kilometers, which is just a reference interval. For commercial vehicles that cover longer distances, the replacement cycle should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Regularly check the coolant level and top it up if it's insufficient. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the coolant, it should be replaced immediately, and the system should be cleaned. Functions of coolant: Coolant is a special additive-containing fluid primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and provides year-round protection against scale and corrosion. Types of coolant: Coolant is generally categorized into three types: ethanol-water, glycerin-water, and ethylene glycol-water. How to choose coolant: The key indicators for coolant are its freezing and boiling points. Available in the market are coolants with freezing points of -15°C, -25°C, -30°C, -40°C, etc. It is advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region.

Antifreeze is like the lifeblood of a car. I've been driving my Teana for ten years, and the manual clearly states it should be replaced every two years or 30,000 kilometers. I never cut corners because I once tried delaying a fluid change, which resulted in engine coolant leakage and cost me over 2,000 yuan in repairs. The Teana's cooling system is somewhat delicate, and the OEM antifreeze formula is better matched. Prolonged neglect can corrode pipes and the water pump. I recommend regularly checking the color of the reservoir—if it turns from blue to cloudy or shows rust, replace it immediately. Don't treat it lightly; freezing in winter or overheating in summer could leave you stranded. Safety is far more important than saving money. Have it changed at a professional shop; the most you can do yourself is visually check the fluid level.

As a mechanic who frequently works on the Teana, I recommend changing the coolant every two years or after exceeding 30,000 kilometers in mileage. Why? As the coolant ages, its antifreeze properties degrade, making it prone to freezing in low temperatures and potentially cracking the radiator. A common issue among Teana owners is neglecting coolant changes, leading to high-temperature warnings and engine core damage from cylinder scuffing. The replacement process isn't difficult, but it's crucial to choose the correct coolant type and avoid mixing with standard products. DIY maintenance includes checking the reservoir level and color changes each season. For a more professional approach, use a refractometer to test the antifreeze index. It's a small investment that can save you from major repair costs. Remember, driving habits also affect the replacement cycle – those who frequently drive on highways should consider changing it slightly earlier.

I've been driving my Teana for five years and stick to changing the coolant every two years. The manual clearly states it should be replaced around every 30,000 kilometers. I've seen the consequences of not changing it on time: a friend's car engine burned out due to deteriorated coolant causing blockages. Checking it yourself is simple: pop the hood and see if the reservoir is clean and clear. If it's yellowish or has sediment, get it changed at a shop immediately. Teana's original coolant is effective and durable, so don't skimp on this expense. Safety comes first—don't wait for a fault warning to act. Regular maintenance keeps your car running smoothly.
