Coolant doubts?

Engine coolant is a heat-transfer fluid (glycol + water + inhibitors) that circulates through the engine and radiator. It prevents overheating, freezing, rust, scale and foam — jobs plain water can’t do.
Mostly yes. “Antifreeze” is the concentrate; “coolant” is the ready-to-use fluid in your radiator. All F Frost series are ready-to-use — pour direct, no mixing needed.
General guide: conventional green every 2 years / 40,000 km; long-life red/OAT every 4–5 years as per manual. Top up if below MIN, and always check hoses, cap and fan if the level drops repeatedly.
Don’t. Mixing green + red or different chemistries can gel, drop protection and void benefits. If switching, drain fully, flush with clean water, then fill one F Frost grade.
Pick by colour: daily car/taxi → Green Series All-Season RTU. Truck, bus or tractor → Blue Series Heavy-Duty. Modern turbo/BS-VI engine needing long life → Red Series Long-Life. Special or purple-spec application → Purple Series. Unsure? WhatsApp your model + year to +91 70164 14787 and we’ll confirm free.
Retail: 1L, 3L, 5L in every colour series. Dealers and fleets can ask about case and bulk options.
No — and with F Frost you never need to. Every series is pre-mixed RTU: pour direct from the bottle, never add tap, borewell or any other water.
