Comma XSG405L Xstream G40 Antifreeze and Coolant Concentrate, 5 Liter, Violet

No problems with this coolant, works well. Concentrate proves to be much better value than ready mixed.

Sorry but this really annoys me that Amazon ask you to review stuff and then ask you to rate the flavour. In the past week I’ve been asked to rate the flavour on coolant for cars (sorry I don’t drink coolant or antifreeze) Rate the flavour on dogs sausages treats (sorry my dog doesn’t talk, or at least not to me) Also rate the flavour of a dog chew, well it didn’t taste of much really apart from dog slavours, plus I picked it up just after the dog had been chewing it leaving a sharp bit and nearly cut my mouth wide open so I will not be trying that again, sorry. Anyway I use this coolant a fair bit as for some reason my car loves to go through it and I would recommend it. Nothing has ever frozen and my car still works so it’s all good for me. Also it was cheaper from Amazon than anywhere else so all good!!

Good Quality and Competitively Priced, not much more expensive for this concentrate than the equivalent ready mixed G40 from Comma.

It's anitifreeze and coolant. It works. Happy days. Nothing else to say. Smells quite nice if you like that kind of thing. Sturdy bottle too.

I am a regular purchaser of this item (unfortunately) due to my coolant disappearing from my reservoir on a regular basis 😆 I prefer this brand to a Halfords branded one. I find it thicker perhaps, not that I would notice any difference in the performance of my car 🤷🏼‍♀️

The coolant in the wife's car is now five years old and the anti corrosion additives dont last forever so I decided to drain the old stuff and replace with this. Good value for money.
