Description
Overview:
The 4.5L Silverhook Concentrated Blue Antifreeze & Summer Coolant is a glycol-based concentrate designed for water-cooled engines in cars, vans, plant machinery and garden equipment such as ride-on mowers and compact tractors. Mixed with clean water, it circulates through the cooling system to manage engine temperature and provide year-round protection. The blue inhibitor package helps guard against rust and corrosion across common cooling system metals, supporting reliable operation over time. When diluted as directed, it offers effective freeze protection down to -36°C and stable cooling performance in warmer weather. Supplied as a concentrate, it allows you to set the mix ratio to suit local conditions and manufacturer guidance. Colour: blue for easy identification. Manufacturer Part Number (MPN): OPTCAFB5V.
