## Questions & Answers

**Q: Is this compatible with mercedes benz 325 ?  its for a 2012 s350 bluetec.**
A: Yes it should be absolutely fine and ideal for every radiator as its just detergent based and not acidic and therefore not harmful. Domt run the engine for too long with it in there 10-20 mins max.

**Q: I’ve not done a coolant change on my 2013 Audi A5 since 2016, this good to put in before changing coolant? Cars done 40k since last coolant change**
A: Yes good product works wonders, make sure to flush twice with clean water after use before filling with coolant

**Q: Will this remove head gasket repair fluid lurking after failed head gasket sealing attempt?**
A: It could start leaking if the cooling system was sealed. I’m not a scientist but it is recommended to keep the sealing agent in the coolant. Not necessarily to flush. Just change.

**Q: my engine takes around 17ltr of coolant how many bottles would i need ?**
A: It’s detergent. The foam does it’s job. You can pour 2 if you want. Just run it 30 min if it is very dirty coolant.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked well for me!
*by  on Reviewed in the United Kingdom 6 June 2026*

I had a Discovery 4 with a blocked Heater Matrix, I stuck this in the system the day before power flushing the sytem, heater perfromance was restored. Very easy to use and much cheaper than replacing a radiator - Should probably be used every time one changes the coolant.

### ⭐⭐⭐⭐⭐ Effective cooling system flush
