Coolant, part of the Lubricants & Fluids range, is a heat transfer fluid used in vehicle cooling systems to regulate engine and component temperatures. Circulating through the engine block, radiator, and heater core, coolant absorbs heat from the engine and dissipates it, preventing overheating and maintaining optimal operating conditions for passenger cars and commercial vehicles. Formulations typically consist of water and ethylene glycol or propylene glycol, with added corrosion inhibitors to protect metallic components. Different vehicle manufacturers specify unique coolant formulations, requiring the use of compatible products to ensure system longevity and performance; examples include Febi coolant (MPN 24196, 01089, 02374) and coolants designed for Volvo Trucks and Volvo Construction Equipment (MPN 11715725). Maintaining the correct coolant level and using the specified type is crucial for reliable vehicle operation.
