Regular maintenance is key to keeping your radiator working properly. Here’s why radiator cleaning is essential for keeping your car on the road.

The safest answer is no. Not all coolants are compatible. Mixing the wrong coolants can degrade corrosion inhibitor performance and in some cases result in chemical reactions that cause blockages in the cooling system. If you’re uncertain about the specific coolant in your system, it is best to use distilled water for temporary topping up. If draining and replacing coolant, the entire system must be flushed to remove all traces of old coolant.

If you’re not sure what coolant your system uses, it’s worth checking out our guide on how to check your car’s coolant level.
