Car is leaking coolant regularly. Have to top up every hour when driving. Garage wanted £400 for parts and labour for a pipe and water pump housing. The car only cost me £1000 decided to just top up coolant every time I drive. Saw this product on amazon. Followed instructions. Didn't have high expectations but thought would give it a go. And so far so good. 3 weeks since I used it and seems to have fixed the leak.

Had to keep filling my coolant up every week, got told it was probably from the water pump. Added this and leak is no longer there 😁

It has worked that well, that I had forgotten I had a leak on the water pump. Now completely gone, no water under car anymore. There’s nothing more to say really, I’ve been driving now for over a month without a problem. I only remembered when Amazon prompted me to write a review for my purchase. I can’t promise it will work for everyone, but it’s worth a go. My leak was visible and now it’s completely gone. Easy to use, I just followed the instructions that came with it. Very happy.
