    Rated 1 out of 5 by It did nothing Slight leak on hose fat hose that feeds the radiator and after following instructions to the letter and driving over 50 miles it's made no difference at all. £4.99's worth of brown liquid. 06 June 2015
    Rated 4 out of 5 by Holts Radweld Did exactly what it said it would it blocked up a leak and was able to use my car until I got a new radiator following week 02 December 2013

    Rated 5 out of 5 by Excellent Product Bought this product as had small crack in heater matrix which was allowing / causing smoke to come into car through air vents when I had the heaters on. Used this product, followed instructions and so far so good. No more problems. Would thoroughly reccomend. 26 October 2012
    Rated 4 out of 5 by Cheaper than a radiator!!! I had quite a severe leak and didn't have the money or time to fix it. Poured a bottle of this in the radiator and it stopped leaking! I know its only a temporary fix but it done the job! 26 June 2012
    Rated 5 out of 5 by amazing product, perminent seal for me! I had a small crack in my radiator after a cold night and I lost almost all coolant in a few hours so it was pouring fast. This product did what it says and after using a bottle and running the engine idle and a quick drive around the block the leak competely stopped and ive had no problems since i used it december 09. I trust this product, an amazing and a money saver. My car is 13 years old and apparently the formula reactivates so it may help seal other weaknesses in the radiator system. 11 October 2011

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.
