Longlife Universal Antifreeze 1L (U913) – Ready-to-Use OAT Coolant

Part Number: EXPU913S1L

Monoethylene glycol–based, ready-to-use engine coolant using Organic Acid Inhibitor Technology (OAT). Free from nitrites, amines, phosphates, borates and silicates (BTC Type 4E), it provides excellent and sustained corrosion protection for modern mixed-metal cooling systems under demanding conditions. Proven long-life performance up to 5 years (≈250,000 km passenger cars / ≈500,000 km commercial vehicles) when used as directed.

Key Features

• Ready-mixed — use as supplied, no dilution required
• OAT long-life corrosion protection; very low inhibitor depletion
• Hard-water stability; compatible with MEG-based coolants*
• NAP-, borate- and silicate-free (BTC Type 4E)
• Colourless for easy leak detection on dyed systems

Applications

• Passenger cars, vans and light commercials
• Aluminium and ferrous cooling systems
• Top-ups and full fills where a ready-mix is preferred

Directions

1. For top-ups, check level when engine is cold; add product undiluted.
2. For full fills, drain/flush per OEM guidance, then fill as supplied.
3. Bleed air, heat-cycle, cool and recheck level.

*Compatible with other MEG coolants; if mixed with traditional (IAT) coolants, service life defaults to the traditional coolant.
