Ford Focus ecoboost leak Ksealed
I have a Ford Focus ecoboost 999c which I understand is prone to overheating and hairline cracks in the engine block This happened to mine My engine overheated and lost a large amount of coolant and I had to top it up and was using 1-2 litres per week Online investigation revealed the fault with the model and the large cost of repair even if possible As a last resort I tried Kseal it worked immediately and sealed the problem That was two years ago Unfortunately a few weeks ago the leak returned On contact with the company under their guarantee a new bottle was sent out within 3days On using the leak has been repaired again if it lasts a further 2 years saving me S I will be pleased Excellent product

Beast in a Bottle
Basically I m an 70-80s old school mechanic and I ve found that mechanics in a bottle usually don t work BUT KSeal sealed an unrepairable head leak without some serious for a disassemble and rebuild which the young lady did not have my buddy tossed me a little bottle of KSeal and in 15 minutes of running it sealed A while back I seen her in that old B M W I asked her how the leak was she replied it never leaked again Bravo to you KSeal IT REALLY WORKS

It worked to seal coolant leak
One day I found coolant level was getting low on my 03 Forester Upon inspection I found coolant was leaking around the water pump housing It was like a drop every 3 sec Replacing water pump was a huge hassle so I decided to try K-seal and bought one from Walmart I removed the radiator cap while the engine was cold connected a funnel put some K-seal and started the engine While the engine was idling I kept putting K-seal in the radiator directly and checked the leak In few min the drop rate started to slow down like a drop every 5 sec and after like 30 min it became like a drop every 20 sec or so I left the car idle for an hour and since then I don t seem to lose coolant anymore at least it wasn t noticeable I don t know whether this is a permanent fix and that s something I will see but for now I am pretty impressed

100 Worth It
This product was 29 99 and saved my engine from thousands of dollars in repairs I was so sure my cracked head gasket was going to fail that I began to look for a new car This product completely sealed it and now my heat gauge never exceeds 40 even driving hundreds of miles on hot days I would definitely recommend Even if you re crack is too big to be fixed it s worth the 30 gamble

Sceptical but worked
I had a serious leak from my Renault megane 2008 After driving for just a few miles engine would over heat and water coolant was on empty As a sceptic I thought this so called liquid treatment surely can t fix the problem however added this magical stuff to my water coolant and it worked No more leaks and driving long distances without problems Great product
