XADO Radiator Leak Repair & Antifreeze Protector 250ml – Cooling System Sealer for All Engines

One Bottle. Zero Leaks. Full Cooling System Protection.

Coolant leaks don’t fix themselves — and ignoring them leads to overheating, engine damage, and repair bills that dwarf the cost of prevention. XADO Radiator Leak Repair & Antifreeze Protector (250 ml) is a high-performance cooling system additive that seals leaks at the source and fortifies the entire circuit against rust and corrosion — no draining, no disassembly, no downtime.

Seals Leaks Across the Entire Cooling Circuit

Once added to the coolant, the formula travels through the full system and bonds to leak points on contact:

• Radiator hairline cracks, pinholes, and seam leaks
• Hose fittings, pipe joints, and connection points
• Head gasket seepage and cylinder block gaps
• Water pump housings and internal coolant passages

Key Benefits

• Fast, Permanent Leak Sealing — targets and closes active leaks throughout the cooling system
• Rust & Corrosion Inhibitor — long-term protection for metal surfaces between coolant changes
• 100% Material Safe — will not harm rubber seals, hoses, gaskets, aluminum, plastic, or steel components
• Universal Engine Compatibility — works in gasoline and diesel engines across cars, trucks, vans, and equipment
• Reduces Repair Costs — a cost-effective alternative to radiator replacement or head gasket repair in many cases
• Use Preventively — add after every coolant flush to protect the system before leaks develop

How to Use

1. Warm the engine to normal operating temperature — warm, not hot. Turn it off.
2. Shake the bottle thoroughly before opening.
3. Pour the entire 250 ml into the radiator tank or coolant expansion reservoir.
4. Start the engine and idle for 5–10 minutes with the cabin heater on full to circulate the product through the complete cooling circuit.
5. Return to normal driving — the sealing action continues during operation.

⚠ For best long-term results, apply immediately after each coolant change to prevent leaks before they start.
