LIQUI MOLY Pro-Line Radiator Stop Leak K | 250 ml | Cooler additive | SKU: 5178, red

Great product worked really quick I had a hair line crack in a plastic water pump housing sealed it up in seconds easy to use and wasn’t that expensive either

Used on Hyundai i40 1.7 cdti that had a very irritating slow leak from somewhere not obvious. I have no intention to plough money into this car.. it's a mobile tip! First time using anything like this as it goes against my inside engineer.... But to be fair, it's been a few months now since adding it and the coolant leak appears to be sealed!

Easy to use and work done 💯, Very happy and value for money.

Seems to have stopped the leak. Always good value if it works. Suppose it depends on how big the mystery hole is.

Stopped the leak and 6 months on, there is no leak. I used it on a 3ltr diesel engine which would have cost hundreds to fix at the garage. It’s best to put it in and go on a long journey to get the system really warm.

It works. Highly recommend.

I bought two bottles because I thought one might not be enough. I poured the first one in, it didn't work, so I poured the second one in, and nothing happened either. Waste of time and money.

We had a 17 told car that had a leaking radiator but we only needed to patch it up to sell it so used this. One thing led to another and a half a year later we still had the car and the liqui moly was still doing it’s thing. £20 or £400 to fix the radiator and this stuff worked wonders!

Aracımda 3-4 günde bir 200ml civarı su eksilmesi oluyordu, ustam bu tip bir ürünün durumu kesebileceğini söyledi, denemek için aldım ve uyguladım, şimdilik su seviyesi aynı görünüyor, eksilme olmamış gibi. Yalnız, alışveriş sayfalarında Türkçe kullanım yanlış yazılmış. Motorun ısınmasını bekleyip sıcak suya konulması gibi bir durumdan bahsediliyor. Nasıl yapacaksınız? :) Ki ürünün arkasında zaten "add to cold cooling liquid" gibi bir ibare yer alıyor. Yani soğukken soğutma sıvısına ekleyeceksiniz. Kalorifer açmaya çok gerek var mı bilmiyorum, maksat araç optimum sıcaklığa ulaşsın, fan açsın ve ürün tüm sistemde dolaşsın, minimum 10dk dolaşın uyarısı bu yüzden.
