What happens if you don’t change the coolant in your car?

The coolant can become more acidic over time and lose its rust-inhibiting properties, causing corrosion. Corrosion can damage the radiator, water pump, thermostat, radiator cap, hoses and other parts of the cooling system, as well as to the vehicle heater system. And that can cause a car engine to overheat.What happens if you dont change coolant? The coolant can become more acidic over time and lose its rust-inhibiting properties, causing corrosion.

How long can you go without changing coolant?

Regular flushing keeps the coolant clean and prevents blockages. HOW OFTEN SHOULD YOU FLUSH THE COOLANT? Depending on the vehicle and the coolant, the average time between flushes is two years or 30,000 miles for silicated coolants and up to five years or 100,000 miles for an extended drain coolant.

Does coolant really need to be changed?

The simplest way to avoid overheating is to service the system every two years or according to your car manual recommendations. Flushing the coolant and replacing it with fresh fluid every two years or 30,000 miles is a good rule.

What happens when coolant gets old?

Yes, engine coolant does go bad. Older fluid may cause acid buildup, may become contaminated by rust or scaling, and may have reduced resistance to boiling and freezing. Deteriorated coolant/antifreeze may cause your engine to run hotter than normal or keep the engine from starting in colder temperatures.

Can coolant last 10 years?

For normal driving of 12,000 to 15,000 miles per year, five years will pass long before the odometer hits 150,000 miles. So, for most applications, five years is the recommended service interval for changing the coolant.
