do you have to flush after ? Or can you just leave in?

You rinse the cooling system with water, flush it out, then refill

how large a radiator does this product clean?

It is based in total coolant volume. If your vehicle's coolant capacity is higher than the recommended maximum dilution quantity, you will need to purchase another.

Is this a 10 minute flush or does it stay in longer?

Follow the instructions on the bottle. It is not recommended to drive with it in nor have multiple engine on/off cycles. Letting the car idle at least 10-15 minutes will not hurt the system, but do not be excessive.

منتج جيد

جيد في تنظيف دورة التبريد الراديتر ، ولكن لاتنسى تسويله فلش بعد التنظيف بالماء المقطر ( لانه مركب شبه صابوني) ويترك اثر رغوه في حال عدم تنظيف مرتين على الاقل بعد الاستخدام.
