Antifreeze – Complete Guide to Choosing Coolant

What is antifreeze and why it matters

Antifreeze isn't just cold weather protection – this coolant safeguards your cooling system from corrosion, overheating and scale buildup year-round. Quality products like TOTAL ANTIFRIZ GLACELF AUTO SUPRA 2F 5/1 ensure optimal engine performance in temperatures ranging from -40°C to +108°C. Regular antifreeze replacement extends the lifespan of your water pump, thermostat and radiator.

G11, G12, G12+, G13 – understanding the specifications

G11 is traditional silicate-based antifreeze in blue or green, suitable for older vehicles. G12 and G12+ use organic acid inhibitors (OAT technology), typically red or pink, and last longer – up to 5 years. G13 is an environmentally friendlier glycerol-based alternative to ethylene glycol, purple in color, and compatible with most modern engines.

Concentrate vs ready-mixed coolant

Antifreeze concentrate must be diluted with distilled water in ratios depending on required protection – usually 1:1 for standard conditions or 60:40 for extreme winter. Ready-mixed solutions are more convenient but less flexible. Always check your vehicle manufacturer's recommendations before adding – mixing different types can cause precipitation and loss of protective properties.

How to choose the right antifreeze for your vehicle

Never select antifreeze by color alone – verify the specification in your vehicle's manual (e.g. VW TL 774-D, MB 325.0, Renault Type D). Brands like Antifriz offer formulations that meet various OEM standards. For modern vehicles with aluminum engine blocks, avoid old silicate-based formulas.

Signs it's time for replacement

Replace antifreeze if you notice color change to dark brown or rust, sediment appearance, or oil contamination in the expansion tank. Most manufacturers recommend replacement every 40,000-60,000 km for organic antifreeze, or every 2 years for older silicate-based formulas. Testing pH value and glycol concentration reveals the true condition of the fluid.

Safety and handling antifreeze

Antifreeze is poisonous – keep it away from children and pets. Ethylene glycol-based products have a sweet taste making them particularly dangerous. Clean spilled antifreeze immediately as it damages asphalt and vehicle paint. Never dispose of old antifreeze in drains – take it to authorized recycling centers or auto service shops.
