## Questions & Answers

**Q: There is no dosage guide it just says treats 50 litres, does that mean if my system takes 10 litres I add only a fifth of the bottle**
A: it will do a 50 litre system, but if you only have 10 litres to do i would use just over a 5th as you have plenty to make sure it does a good job

**Q: Is this added to only water? I thought that would make the cooling system boil, which the steam would build too much pressure**
A: Worked well for me when used as per instructions

**Q: Is this added to coolant or water? Surely adding it to water only would make it boil.. And the steam would build excess pressure in the system**
A: Empty your coolant out, fill with water and flush, run car for half an hour or so and then flush it all out
