The cooling system’s job is to keep the engine at the right temperature for optimal performance. The engine’s pipes and ducts are continuously supplied with coolant by the mechanically driven water pump.
After the first 210,000 km (140,000 miles) or 120 months, the coolant should be changed. Thereafter, it should be changed every 30,000 km (20,000 miles) or every 24 months.
We’ll look at the causes of coolant leaks in cars in this article, along with how frequently they occur. Along with that, we’ll examine the consequences of not changing your coolant on schedule.
How Long Does Coolant Last
The lifespan of the car’s coolant is typically 40000 to 50000 km (24000 to 31000 miles) or 2-5 years, depending on the coolant’s type and color. You should visually inspect the engine for impurities while performing the overhaul and check the coolant level in the tank. Turbidity and a shift in color denote the presence of foreign materials in the coolant or a modification of the composition’s properties.
The following signs indicate the need to clean the cooling system and replace the coolant:
- Frequent overheating and boiling of the coolant
- Continuous operation of the internal combustion engine at a critical temperature
- Interruptions when starting a hot engine
- The rheostat’s response changed, and the pump had issues running.
Anytime this happens, or if the coolant starts to turn reddish, the cooling system needs to be cleaned right away, and the coolant needs to be changed.
You must take your car in for maintenance after a certain amount of miles have been covered or when cooling system issues are discovered. Are you interested in learning how long a car’s coolant lasts? You can discover a thorough response by reading on.

What Are the Factors That Influence the Coolant’s Lifespan?
The frequency of changing a car’s coolant should be based on information provided by the automakers, but adjustments must be made while taking into account the unique features of each vehicle. When addressing this issue, it is necessary to take into account the following:
- Type of fuel.
- operating circumstances of the car.
- The car’s total mileage.
- the automobile’s mechanical state.
- the kind of oil used—mineral, synthetic, or semi-synthetic.
- The engine capacity.
- Generally speaking, the coolant change interval is influenced by how the car is used.
How Long Does Coolant Last Depending on Its Color?
Radiator fluids coming in various colors is another perplexing aspect. The color convention was introduced for several reasons:
- To provide a clear and simple indication in the event of refilling or changing the coolant
- to offer a cooling system of higher quality.
Naturally, each color has a unique meaning and a different chemical makeup, making it appropriate or inappropriate for particular car models.
Pink Coolant
This is one of the contemporary fluids used as coolants. The organic technology used to create the pink coolant, which is compatible with the G12, is based on carboxylic acid.
The pink coolant liquid can be used as an enhancement or a complete renewal to increase efficiency. Although the average lifespan is supposed to be 5 years or 130000 miles (210000 km), the pink coolant’s lifespan varies depending on the operating conditions.
Purple Coolant
This is a synthetic, high-performance radiator coolant that is compatible with G13, a more recent antifreeze type used in contemporary cars, and it lowers engine heat by loosening the fluid tension in the radiator to improve heat transfer.
It encourages the best possible coolant flow by preventing the buildup of scale deposits in radiators. A typical lifespan of 3 to 5 years, or 150 000 miles (240 000 km), is given by the purple coolant liquid.
Green Coolant
It is a silicate-containing liquid with an ethylene glycol base that Renault primarily uses, though Nissan, Citroen, and Hyundai engines occasionally use it as well.
Overall, it is a liquid that the market does not have much demand for. Be very careful not to become confused because this liquid typically has a light green color that leans toward yellow. Your green coolant should be changed every three years, depending on the environment in which your car operates.
Red Coolant
The red liquid, which has become more common in recent years and is used in all contemporary engines, was first introduced to the market in 1997. The additives in this new liquid are one of its main distinctive features.
It does not contain silicates or phosphates, unlike blue/green and yellow liquids, which do. Organic additive technology, also known as technology with organic additives, is the abbreviation used to refer to it. The typical lifespan of red coolant fluid is two years.
Orange Coolant
The orange coolant, which is typically a blend of IAT (Inorganic Acid Technology) and OAT (Organic Acid Technology), lasts for five years or 150000 miles (240000 km) on average.
How Often Should I Put Coolant in My Car?
How often should coolant be topped off? | Jerry, I just topped off my coolant, but the temperature readings on my car’s thermometer are absurdly high. Am I supposed to add more coolant? How frequently should coolant be refilled? Since you should still have coolant for another year, your high temperature readings are a little concerning.
- You typically need to flush and fill your coolant every two years or 30,000 miles,
- It’s possible that a leaky gasket or a damaged hose is causing coolant loss if you notice higher-than-normal readings on the thermometer in your car.
- In that situation, you ought to visit so that they can perform diagnostics.

Is Coolant a Lifetime?
When a good coolant turns bad: The ethylene glycol in most coolants degrades over time, primarily into glycolic and formic acids. Electrolytic corrosion begins to eat away at the metal inside the engine and radiator as corrosion-inhibiting chemicals run out.
Engine metals are susceptible to corrosion when a coolant has deteriorated and the pH has fallen. Motor Werke is all about preventative maintenance, as many of you are aware. Most manufacturers recommend coolant replacement between 3-4 year intervals; some manufacturers call their coolant “lifetime” but this can be quite misleading.
Final Thoughts
The proper operation of the engine in your car depends on coolant. In light of this, it’s time to have your car’s coolant flushed if you notice any of the warning signs listed above.
If necessary, a mechanic will be able to flush the system and check the coolant’s level and condition. A sufficient amount of coolant must be in your car before the winter.
FAQs
How Often Should I Put Coolant in My Car?
Every 30,000 miles or two years, you should flush and refill your coolant. If the temperature readings on your car’s thermometer are higher than usual, you may be losing coolant due to a leaking gasket or a frayed hose. So that they can perform diagnostics, you should visit a mechanic right away.
How Does Coolant Run Out Fast?
Age and dirty coolant are the two most frequent causes of antifreeze leaks, though other factors can also contribute. Dirt or oil in your coolant can hasten system wear and cause leaks at gaskets, o-rings, or water pumps. The best way to stop this kind of leak is by flushing your cooling system.
Can a Car Run Out of Coolant?
Can a car operate without coolant for how long? Without coolant, progress will be difficult. If so, the engine will begin to overheat after a few miles and may shut off automatically to prevent internal parts from being damaged by heat. You run the serious engine risk of driving it if it doesn’t have this safety feature.
