    I had researched this product and was sceptical as i read a few fiesta owners of which i am one, saying the product had caused a few other issues, psrticularly i their heating system in the car. I was losing an incredible amount of coolant with a leak somewhere, i decided to take a chance. I've given it a month to see exactly what it did to the car. In my opinion it is absolutely amazing. I use my car all day every day, no coolant added since i got this product. Amazing thank you

    Much prefer this product as in my opinion it's far better and less messy than Radwell. Did a cracking job. After doing my water pump properly and still having a bit of a leak seal nailed it.

    The cheeper quicker hassle free alternative

    This was something recommended to me by a friend. and now my car love's me again. it's fantastic easy to use small enough to keep in your car as an emergency tool. if you're car is getting hot under the collar, try k-seal before going to a garage and it may save you hundreds in labour and parts and a lot of time too. all instructions for use are easily understandable, (warnings too) I wish I'd invented it.

    K seal

    Used in my ford mondeo mk4 diesel. and ended up choking up my radiator and heater matrix giving me bad back pressure and causing low or no flow through coolant system forcing coolant out expansion bottle also had no heating as heater matrix got choked up with the k.seal. ended up having to flush out full coolant system and radiator and matrix as was loosing coolant due to blockage and forcing coolant out of expansion bottle .maybe work for other cars but wouldnt recomend for mk4 mondeo 1.8tdci as caused a small coolant leak to turn into major problems before i added to coolant system could run car for 150 to 250 miles before adding coolant and after adding k.seal car overheated on a 2 mile run .

  • No fix because..

    Perhaps its a nice product but in my occasion did nothing because i had the type of head gasket problem that exhaust gases mix with coolant so because of the pressure no k-seal mixed with coolant can reach the head gasket leak

  • Tried them all

    Yes I've tried them all over the cars I've owned, I won't mention any brands, but this is the only one that jot only works, permanently works! Or at least plenty long enough to save up the cash to fix the job properly. Don't waste your time with others, this is the best!

  • Excellent if used correctly!

    If used correctly this works great this saved me over £1000 used on a super bike, will only seal small leaks so don't moan if it don't seal a massive hole , mix with coolant 1st and put directly in to radiator and DONT use too much, less is best I used just under half a bottle on a massive 1448cc superbike, those that moan about it clogging up parts used too much 👍
