Purpose and Specifications

MOTUL INUGEL EXPERT ULTRA is a concentrated antifreeze coolant designed to protect your engine's cooling system year-round. This product must be mixed with soft water before use—it is not ready to use straight from the bottle.

This coolant works in passenger cars, commercial vehicles, and heavy-duty equipment. It protects against freezing in winter and provides excellent heat transfer to keep your engine running at the right temperature. The formula is nitrite-free, amine-free, and phosphate-free, making it compatible with modern engine materials including aluminum radiators, seals, hoses, and plastic components.

Key Protection Features:

• Prevents freezing down to temperatures depending on your water-to-concentrate ratio (typically -25°C to -37°C when properly mixed)
• Stops rust and corrosion on metal engine parts
• Improves cooling efficiency for better engine performance
• Contains a bitter agent to prevent accidental ingestion
• Boiling point of 174°C (345°F) for high-temperature protection

Color: Dark blue-green

When to Use / Replace?

Replace your coolant every 2 years or 40,000 km, whichever comes first. If your vehicle runs hotter than normal, loses coolant frequently, or shows rust-colored deposits in the radiator, change it sooner. Always check your vehicle's owner manual for specific intervals.

This concentrate is ideal for spring and fall maintenance when you're preparing for seasonal temperature changes. Mix it properly with distilled or soft water according to your climate—colder regions need higher concentrate ratios for better freeze protection.

Frequently Asked Questions

Q: Can I mix this with my current coolant?
A: Yes, INUGEL EXPERT ULTRA can be mixed with other monoethyleneglycol-based coolants. However, for best results, perform a complete coolant flush and refill rather than topping off with a different brand.

Q: What ratio of water to concentrate should I use?
A: This depends on your climate. Refer to the product's mixing chart on the label. Typically, a 50/50 mix provides freeze protection to around -37°C and boil protection to 174°C. Colder climates may require up to 60% concentrate.

Q: Is this safe if accidentally ingested?
A: No. The product contains ethylene glycol, which is toxic. The bitter agent added helps prevent accidental swallowing, but keep it away from children and pets. Seek medical attention immediately if ingested.
