## Questions & Answers

**Q: Can this be mixed with tap water or is distilled water necessary?**
A: De ionised water is the best bet. Tap water especially hard has minerals that after a while can clog your radiator

**Q: can you mix the speed flush in the system with new coolant for long period**
A: This item is for flushing the system, not for mixing like radweld

**Q: Is it possible to flush out 100% of liquid? if not is it ok to have a small amount of holts cleaner left in the cooling system? thanks!**
A: Hi, how much you get out is dependant on the cooling system design, but you can just keep running water through until it's clear. A small amount left shouldn't affect the new coolant.

**Q: How good is this removing oil from the coolant ?**
A: It’s a waste of money does not work
