FAQs
How often should I use Radiator Relief Flush?
It is generally recommended to use a radiator flush as part of a routine cooling system maintenance, typically every 2-3 years or when replacing coolant, or if you notice signs of reduced cooling performance.
Can I use tap water instead of distilled water?
While the product will function with tap water, using distilled water is recommended for best results as it prevents introducing additional minerals into the cooling system.
How much product do I need for my vehicle?
The 473ml bottle is typically sufficient for a standard passenger vehicle cooling system. Always refer to the specific instructions on the product label for exact dilution and application.
Will this flush remove permanent coolant?
This product is designed to remove rust, mineral deposits, and oily buildup. It should be used as a cleaning step before refilling with your new, appropriate coolant.
Is this product safe for all cooling system components?
The biodegradable formula is designed to be safe for typical cooling system components when used as directed. However, it's always good practice to consult your vehicle's service manual.
What should I do with the old coolant and flush mixture?
Dispose of old coolant and flush mixture responsibly according to local environmental regulations. Never pour it down drains or onto the ground.
Troubleshooting
Cooling system still overheating after flush
Ensure all air pockets were purged from the system after refilling. Check for other potential cooling system issues like a faulty thermostat, water pump, or radiator fan.
Flush fluid not circulating
Verify the engine was run with the heater on high and that the thermostat opened, allowing the flush to reach all parts of the system.
Cloudy residue remains after flushing with water
Perform additional flushes with distilled water until the water runs completely clear. Ensure all drain plugs are properly reseated.
