How Often Should I Top Up Coolant/Antifreeze?

You should check your level of coolant regularly and top up as necessary. Check your vehicle’s handbook for more information on this. If you find you have to top up the coolant every day or every week, you might have a leak and should have it checked by a trained professional mechanic just to be on the safe side.
