Holts Wondarweld Heavy Duty Crack Repair - 500ml (WW500)

Permanently seals cracked cylinder blocks, internal and external leaks in water jacket.

• Suitable for steel, iron and aluminium engines.
• Prevents the need for engine rebuild

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; leakages at the bottom of the cylinder gasket. Comes in a 500ml bottle.
