- Can I mix coolants?
The safest answer is NO. This is because it can be difficult to know for sure which coolant is in the engine, whether it has exceeded its service life, and if it contains contaminants. The best practice is to flush the cooling system and fill it with fresh coolant. Your Natrad technician can check the quality of the coolant present and perform a full system flush if required.
- What does the colour mean?
The colour comes from an added dye that manufacturers use to identify different products. Coolant should be selected based on suitability for the vehicle, not colour. Your Natrad technician can provide advice on the best coolant for your application.
- When do I need to use antifreeze anti-boil coolant?
Antifreeze anti-boil should be used when the vehicle is exposed to extreme temperatures. For most regions in Australia, a corrosion inhibitor coolant will provide more effective cooling. Check your manufacturer’s handbook or ask a local Natrad technician whether antifreeze anti-boil should be used.
- Will replacing my vehicle's antifreeze and anti-boil void the manufacturer's warranty?
The coolant supplied by Natrad will not void any manufacturer’s warranty.
- What's the best product to use for 'top ups'?
Topping up should be done with a pre-mixed version of the same coolant already in the system. If you are unsure about the coolant in the system, top up using high quality, ideally distilled or demineralised water.
