How do I know when my car coolant needs to be changed?
It is normal practice for the interval to be every 24 to 48 months, however your vehicle’s service manual will show the recommended coolant changing interval. It is important that you use coolant that adheres to the specifications recommended by the manufacturer. In most cases you will be able to use coolant that has the same specifications as the manufacturer-branded coolant, but is generically labelled. In any case, it is also important not to mix two different types of coolant.
