What coolant does the Discovery Sport use?
2 Answers
The Discovery Sport uses a coolant composed of 50% water and 50% antifreeze that meets the Jaguar Land Rover specification STJLR.651.5003. It is recommended to choose a coolant with anti-corrosion and anti-scale properties. Anti-corrosion: Corrosion in the cooling system can cause failures in the radiator's lower tank, fuel injector sleeves, cooling pipes, joints, and radiator tubes. Additionally, corrosion products can clog the pipes, leading to engine overheating or even complete failure. If corrosion causes perforation, coolant leakage into the combustion chamber or crankcase can cause severe damage. When coolant or water mixes with engine oil, it creates sludge and deposits, weakening lubrication and causing valves, hydraulic valve lifters, and piston rings to stick. Therefore, coolants contain a certain amount of anti-corrosion additives to prevent corrosion in the cooling system. Anti-scale: The coolant should minimize scale formation during circulation to prevent clogging of the pipes and maintain the cooling system's heat dissipation efficiency.
What coolant does the Discovery Sport use? I've driven this car for several years, and it requires an ethylene glycol-based Organic Acid Technology (OAT) type coolant, typically the Land Rover specified specification, such as G12-compatible. I always check the owner's manual during maintenance—it clearly states which coolant to use. Don’t buy the wrong one casually, as it can easily corrode the radiator or pipes. The replacement interval is roughly every two years or 50,000 kilometers, depending on the vehicle's usage intensity. Be sure to check the coolant level before summer or winter—too high or too low affects cooling efficiency. If unsure, use a test strip to measure concentration and ensure the antifreeze point suits local temperatures. I opt for the OEM brand—affordable but with good compatibility—to avoid mixing different types and causing sediment. Routine maintenance is simple: regularly check for color changes in the coolant; if it turns from pink to cloudy, it’s time for a replacement. Safety first.
