Getting the optimal performance out of your car can mean spending vast amounts of money at garages that do not always solve the problems. Sometimes simply cleaning and protecting your car's various systems can have a dramatic performance effect. Radweld is the UK's number one leak repair product. Used to stop leaks in radiators and hoses, it also contains anti-corrosion properties to offer long lasting protection. Unaffected by anti-freeze, there is no need to drain the system and is safe to use with rubber hoses. Radweld is suitable for all cars and all anti-freeze, and is the number one product for sealing leaks in your radiator system. Founded in the United Kingdom more than 65 years ago, Holts has become an industry leader in the manufacture and global distribution of automotive aftermarket products.
