VP Racing Madditive Cool Down Coolant Additive – 473ml (16oz) • 2085

VP Racing Madditive Cool Down is a specialist cooling system performance additive designed for compatible liquid-cooled petrol and diesel engines, including road, performance and motorsport vehicles. Formulated to improve heat transfer and cooling efficiency, Cool Down helps manage engine temperatures under demanding operating conditions.

Its advanced formula reduces coolant surface tension, helping transfer heat more efficiently from hot engine components into the cooling system. VP Racing reports reductions of up to 30°F (approximately 17°C) in coolant temperature and up to 75°F (approximately 42°C) in cylinder head temperature under suitable conditions.

In addition to its cooling benefits, Cool Down lubricates vital components including water pumps and seals, while helping protect cooling-system metals, particularly aluminium, against corrosion and electrolysis.

Suitable for use in compatible antifreeze/coolant mixtures or straight-water cooling systems, Cool Down is particularly useful where improved thermal management is required during spirited road driving, racing, track days or extended high-load operation.

Fitment advice: Cool Down is a universal cooling-system treatment rather than a vehicle-specific replacement component. It is suitable for compatible liquid-cooled petrol and diesel engines where supplementary coolant additives are permitted. Always follow the vehicle manufacturer's coolant specification and maintenance requirements, particularly where a specific long-life coolant formulation is required.

Other items to consider: When servicing the cooling system, you may also want to consider purchasing the correct engine coolant, replacement radiator caps, cooling hoses, thermostat assemblies, hose clamps and other cooling-system service components.

Useful tools / consumables: Suitable filling funnel, protective gloves, coolant measuring equipment, clean cloths, coolant tester and a suitable container for collecting drained coolant where required.

Difficulty guide: DIY Difficulty: Easy. The additive is introduced into the engine cooling system according to the manufacturer's dosing instructions. Allow the engine to cool completely before opening the cooling system.

Why VP Racing? VP Racing is an established motorsport fuels, lubricants and additives manufacturer. Its Madditive Cool Down formula is developed to improve heat transfer while providing additional cooling-system lubrication and corrosion protection. It offers a practical performance-focused treatment for compatible vehicles operating under demanding thermal conditions.

What's in the bottle: 1 × 473ml (16 US fl oz) bottle of VP Racing Madditive Cool Down Coolant Additive.

Installation / service notes: Add Cool Down according to the manufacturer's instructions and total cooling-system capacity. One bottle is intended for approximately 11.4–18.9 litres of cooling-system capacity. For straight-water applications, the manufacturer recommends 50% more additive than the standard treatment quantity. Do not open the cooling system while hot or pressurised. Ensure sufficient space is available before adding the treatment and maintain the correct coolant concentration where antifreeze is required. Cool Down is not a replacement for repairing defective cooling-system components or maintaining the correct antifreeze protection. Follow the manufacturer's recommended treatment interval of one year or 30,000 miles, whichever comes first.
