Silverhook D/ISHA1 Concentrated Antifreeze Coolant - Blue - 1 Litre

Silverhook Fully Concentrated Antifreeze Blue is a year-round engine coolant designed to regulate temperature and protect against extreme temperatures. This concentrated formula provides protection from freezing down to -36°C and from boiling over in high heat. Composed of ethylene glycol with a high-performance additive package, it offers corrosion inhibition to protect all engine metals, including full-aluminium blocks, and helps prevent rust, scale buildup, and internal wear within the cooling system. The low-viscosity fluid supports efficient heat transfer and maintains system cleanliness through detergency, reducing the risk of water pump seizure and protecting rubber components from drying and cracking. Suitable for all engine types, this BS6580:2010 compliant antifreeze supports reliable year-round operation and helps maintain stable engine temperatures and cooling-system longevity.
