Description

Ravenol OAT coolant for Td5 and later Land Rover cooling systems

Ravenol OTC C12+ is a concentrated OAT coolant for Land Rover vehicles that specify STC50529 coolant. It is the correct coolant type for Td5 cooling system service work and other Land Rover applications that require long-life organic additive technology coolant.

Use this coolant when refilling the system after radiator, water pump, thermostat, hose or general cooling system work. It is also suitable for a full coolant change where the existing coolant is old, contaminated or of unknown type.

This is concentrate, not ready-mixed coolant. For most Td5 and Land Rover use, mix 1:1 with distilled water to make approximately 10 litres of mixed coolant from this 5 litre container. Before filling, flush the system, check for leaks and avoid mixing different coolant types unless the system has been properly cleaned out first.
