Anything that contains real carbon fibre is always all right with us. That said, this is definitely the first time we’ve seen a coolant leak buster made of the stuff – it’s obviously the Bugatti Veyron of the additives world!

OK, maybe not. But what is special here is that the carbon replaces the copper filings that many products of this type use. So while it’ll still search out leaks to permanently seal them, it won’t clog up the rest of the system. Apparently, you can even use this as a preventative measure too.

Now what with the shitty weather, you might think cooling isn’t the biggest problem at this time of year, but it’s actually winter when most leaks rear their ugly heads.

In the vast majority of cases this is due to heavily-diluted coolant freezing and expanding, because the water is overpowering the antifreeze.

Anyway, a bottle of this stuff could get you out of trouble with any engine up to four litres, and we reckon that’s got to be worth a tenner!
