Red OEM Coolant is a GENUINE GLYSANTIN® G40® Original Equipment Manufacturer (OEM), fully licensed and warranty approved, type "A" ethylene glycol, anti-freeze anti-boil coolant as used in initial manufacturer factory fills. It uses a technically advanced Si-OAT (Organic Acid Technology) based inhibitor system that is Phosphate, Amine, Borate and Nitrite free. The extended long life inhibitor formulation prevents rust, corrosion, cavitation and degradation of the cooling system for 8 years or 500,000km. It is available in both concentrate and premix formulations.

PLEASE NOTE: Red OEM Coolant Premix replaces 8 Year 500,000 KM Red Coolant Premix and 6 Year Extended Drain Anti Freeze Anti Boil Coolant


Red OEM Coolant is suitable for the cooling systems of petrol, LPG, light and heavy duty diesel engines that require full Si-OAT Type A anti-freeze / anti-boil / anti-corrosion properties.

Red OEM Coolant is suitable for cars, 4WD's, motorcycles, light & heavy duty commercial vehicles, construction and agricultural equipment. It is especially suited to vehicles of European origin such as Audi, Bentley, Bugatti, Lamborghini, VW, Seat and Skoda (all 2008 on), MAN trucks (Dec 2011 on), Mercedes-Benz trucks (Oct 2011 on) and Porsche (911, Boxster, Cayman, Cayenne, Panamera) 1997 onwards.

Red OEM Coolant provides extended long-term protection against rust and corrosion for all materials used in the engine and in the cooling system construction. It protects cast iron, aluminium, copper and solder alloys as well as the hoses, seals and plastics. It is especially effective in all aluminium engines that are under load or used in extreme hot and cold climates. It may be used in all types of vehicles that use red, magenta or orange coloured initial fill coolants and it is also suitable for use in out of warranty service to maintain OEM performance. It is also ideal for motorcycles.

Red OEM Coolant Premix is a 50% concentration formulation and is ready to use directly from the container. It is pre-mixed with Penrite De-Mineralised Water and can be poured directly into the cooling system. No further dilution is required. It can be used as a complete service refill, top up or is safe to mix with compatible type A coolant. Penrite recommend that a 50% concentration level should be maintained for maximum, performance and longevity of the coolant and protection of the cooling system.


Penrite recommend flushing the cooling system prior to a complete service refill. Penrite Radiator Flush effectively cleans the system in 7 minutes and prepares the cooling system for new coolant.
