When a crack appears it should be dealt with straight away, left untreated a small issue could develop into needing a whole new engine block. It would be great if you were able to replace these problems rather than replace the part. This is where Holts have invested their technological know-how to come up with a modern and practical solution. Wondarweld is designed to repair cracks in a car's engine block. Suitable for steel, iron and aluminium engines, it prevents the need for an engine rebuild whilst resisting high temperatures, water pressure and vibrations. Wondarweld can solve several types of engine problems including external cracks, which occurs when the coolant fluid leaks (either because the engine has frozen or there is damage to the head gasket); internal cracks (gas mixing with water resulting in bubbles entering the expansion chamber, white smoke at the exhaust, hardening of flexible pipes (due to the contamination between the compression in cylinders and the coolant system) and leakages at the bottom of the cylinder gasket. Comes in a 250ml bottle. 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.
