## Description

Liqui Moly Radiator Cleaner | 300 ml | Cooler additive | SKU: 2051

Review: Easy cooling system flush that removes sediment and improves circulation - I added this Liqui Moly radiator cleaner during a coolant flush on an older vehicle. The additive mixes quickly, and after letting the engine run, I could see the old coolant draining out with noticeably more debris than a water flush alone. The bottle is the right size for a single treatment, and the instructions are clear. After flushing and refilling with fresh coolant, the engine temperature held more consistently, especially during longer drives. Minor note: it’s important to run the heater while circulating the cleaner so it reaches the full system — not really a con, just part of the process. For anyone doing DIY coolant maintenance, this helps get a more thorough clean.

## Questions & Answers

**Q: do you have to flush after ? Or can you just leave in?**
A: You rinse the cooling system with water, flush it out, then refill

**Q: Can this be used with aluium rad**
A: Yes

**Q: how large a radiator does this product clean?**
A: 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.

**Q: Is this a 10 minute flush or does it stay in longer?**
A: 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.
