How long does Hyundai coolant last?
Newer coolants use an Organic Acid Technology (OAT) and last up to twice as long as older coolant. In some cases these long-life coolants can last over 5 years or 100,000 miles.
How often does coolant need to be replaced?
Periodically Change Your Car’s Radiator Fluid Most car manufacturers recommend that you change the radiator fluid in your vehicle every 24,000 to 36,000 miles, or every 24 to 36 months. However, your personal driving habits will also determine the frequency of needed radiator fluid changes.
How do I know when my coolant needs to be changed?
here are some telltale signs that your vehicle’s coolant is likely past its prime, and needs to be replaced:
- your coolant is dark, murky, smelly or full of debris. if your coolant looks (or smells) bad, it’s way past its useful life.
- your temperature gauge reads higher than normal.
- your engine overheats.
How often should engine coolant be changed in years?
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. You can tell which type of coolant you have by the color.
Do I really need to change my coolant?
The simplest way to avoid overheating is to service the system every two years. Flushing the coolant and replacing it with fresh fluid every two years or 30,000 miles is a good rule.
What happens if you never change coolant?
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.
Does engine coolant expire?
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.
