According to most carmakers the lifespan of antifreeze/coolant is around five years or 100000 miles whichever comes first. Some antifreeze can last much longer. The important thing is to check your antifreeze/coolant mixture regularly and top it up when necessary.
Topping up your antifreeze/coolant mixture is important because over time the water part of the mixture can evaporate leaving the coolant unable to do its job properly. In other words it can no longer protect your engine from overheating.
If you’re topping up your antifreeze/coolant mixture more frequently than usual it’s a good idea to get your cooling system checked out by a mechanic to make sure there are no leaks.
While most carmakers say that antifreeze/coolant has a lifespan of around five years or 100000 miles there are some factors that can shorten this. For example if you frequently drive in hot climates the mixture will break down faster.
If you’re unsure about how often you should be checking and topping up your antifreeze/coolant mixture consult your car’s owners manual. And as always if you have any specific concerns it’s best to consult a mechanic.
