How Much Coolant Should Be Added to a Land Rover Discovery Sport?

For the Land Rover Discovery Sport, coolant should generally be filled up to the "MAXT" mark on the reservoir. The steps for replacing coolant are as follows: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with particular attention to the five-way hose. The five-way hose is named for its five connections to different parts of the vehicle, and coolant is distributed to various sections of the car after flowing through it. If there is any coolant leakage in this area, replace the hose or resecure the connections as needed. Drain the old coolant, then flush the fluid channels with clean water. Add clean water to the coolant reservoir and continue filling until water flows continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may have a faint pink tint. Keep adding clean water until the outflow is clear. Remember to disconnect the heater hose and drain the water from the heater core. After draining for about an hour, add new coolant through the radiator hose to allow it to flow quickly into the radiator. Then, pour another container of coolant into the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. As some air is expelled from the cooling system, the fluid level will drop slightly. Top up the coolant again until it reaches the "MAXT" mark on the reservoir.
I often top up the coolant in my Discovery Sport by myself, and I've learned the amount isn't a fixed number. The key is to refer to the MIN and MAX lines on the coolant reservoir. When I add coolant, I usually use a 50% antifreeze and 50% distilled water mixture, filling it up to the MAX mark. The total capacity is roughly 5 to 7 liters, but the actual amount depends on the current fluid level—don't just memorize numbers. The Land Rover owner's manual has specific details; I recall it being around 6 liters for my 2018 model. I always do this when the engine is cold to avoid burns and wear gloves for safety. Getting the mixture ratio right ensures optimal antifreeze performance. Overfilling can cause the liquid to expand and overflow, damaging the system. I change it every two years to clean out sediment and prolong engine life. This method has worked well for me over the past three years—no cooling issues and it saves a bit of money too. Very practical.
After driving this car for over a decade, I've learned that coolant level isn't just a random number. First, check the expansion tank's marked lines - usually LOW and FULL - filling to the FULL position is most stable. While the manual specifies a capacity between 5 to 7 liters, don't rely solely on that. I always mix 50% coolant with 50% distilled water to maintain proper ratio. Check and top up only when the engine is cold for safety - never rush. Overfilling can cause boiling overflow and pipe corrosion. I perform quarterly maintenance checks to prevent winter freezing or summer overheating. Always use dedicated green coolant and avoid mixing brands or colors. Following these practices kept my engine running efficiently for 6 years without major repairs - sharing with fellow car enthusiasts.
