Q: Is ArctiFlow really non-toxic?
A: Yes. ArctiFlow is built on USB-Grade Propylene Glycol (PG) — the same pharmaceutical-grade ingredient classified as GRAS (Generally Recognized as Safe) by the FDA under 21 CFR 184.1666. It contains zero ethylene glycol, zero DEA (diethanolamine), zero boric acid, and is NOT on the California Proposition 65 list. It's the world's first high-performance antifreeze built entirely on a non-toxic base.
Q: Can I use ArctiFlow™ in my car / truck / SUV?
A: Yes. ArctiFlow LD Desert meets ASTM D3306 — the standard specification for passenger car and light truck antifreeze — along with D4340, D4985, D1384, D2570, JIS K-2234, MIL-A-11755, and MIL-PRF-11352. Use the Vehicle Finder to confirm compatibility with your specific year, make, and model.
Q: What's the difference between LD and HD?
A: LD (Light Duty) products meet the standard passenger car, SUV, and powersports antifreeze specifications (ASTM D3306 and related). HD (Heavy Duty) products add ASTM D6210 and D6211 compliance — required for diesel engines in Class 8 trucks, tractors, heavy equipment, and commercial vehicles. HD also adds enhanced inhibitor protection for diesel cylinder liners, wet sleeves, and heavy-duty aluminum components.
Q: What's the difference between Desert and Arctic?
A: Desert (50|50 pre-blended) provides freeze protection to −34°F / −37°C — ideal for most of North America, automotive, and standard powersports use. Arctic (60|40 pre-blended) provides freeze protection to −76°F / −60°C — the world's first antifreeze rated to this level. Arctic adds MIL-C-11750 military extreme cold specification. Choose Arctic for snowmobiles, extreme cold environments, northern fleets, and any application where temperatures drop below −34°F.
Q: Is ArctiFlow pre-mixed or concentrated?
A: ArctiFlow Antifreeze (LD Desert, LD Arctic, HD Desert, HD Arctic) is pre-mixed and ready to use — no water needed. ArctiFlow Racing Coolant is a concentrate — mix 1 Liter with 49 Liters of HIGH QUALITY R/O water only.
Q: What water should I use with Racing Coolant?
A: High Quality Reverse Osmosis (R/O) Water ONLY. Do NOT use tap water or deionized water. If you question your water quality, contact us at customerexperience@speedteq.com or visit www.speedteq.com.
Q: Is ArctiFlow™ compatible with my existing coolant?
A: We strongly recommend a complete cooling system flush before converting to ArctiFlow. Use ArctiFlow Cleanser (Step 1) — a citric acid dissolvable tablet that removes scale, deposits, and old inhibitor residue — before filling with ArctiFlow™. Do not mix ArctiFlow™ with ethylene glycol-based coolants in service.
Q: What is the ArctiFlow Cleanser and do I need it?
A: ArctiFlow Cleanser is a citric acid dissolvable tablet that prepares your cooling system for ArctiFlow. Drop it in your existing coolant, run the engine to operating temperature, drain, flush with R/O water, then fill with ArctiFlow. We recommend it for every conversion — it's the same cleaning chemistry recommended by Volvo Penta in their official service bulletin.
Q: Is ArctiFlow™ FIA legal?
A: ArctiFlow Racing Coolant Concentrate is FIA compliant and legal in all pavement motorsport series including Formula 1®, IndyCar®, MotoGP®, NASCAR®, NHRA® Drag Racing, club racing, and karting. NOTE: ArctiFlow Racing Coolant CONTAINS NO ANTIFREEZE and is not suitable for applications requiring freeze protection.
Q: Is ArctiFlow safe for Marine use?
A: Yes — and it's actually the safest antifreeze for marine applications. ArctiFlow™ Desert is built on USB-Grade Propylene Glycol (PG), which is non-toxic to aquatic life. If coolant enters a marine bilge and the bilge pump activates, PG enters the water safely. Ethylene glycol (used by all competitor marine antifreeze products) IS toxic to aquatic life and can trigger environmental incident reporting. ArctiFlow™ is compatible with all closed/fresh-water cooled marine engines.
Q: Does ArctiFlow meet NFPA fire sprinkler requirements?
A: ArctiFlow LD Desert meets NFPA 13 and NFPA 25 requirements for fire sprinkler antifreeze systems. NFPA 13 (2013 edition+) mandates that all new fire sprinkler antifreeze systems use propylene glycol — ethylene glycol is NOT permitted in new sprinkler installations. ArctiFlow USB-Grade PG at 30-40% concentration is the exact specification match. Note: The ArctiFlow Antifreeze label states NOT for fire sprinkler use — please use only our dedicated NFPA-certified 38% formulation for fire sprinkler applications [coming soon].
Q: Is ArctiFlow SAFE for EV and hybrid cooling loops?
A: Yes. ArctiFlow LD Desert is compatible with electric vehicle and hybrid thermal management loops that use glycol-based coolant. Many EV and hybrid systems (Tesla, BMW i-series, Porsche Taycan, Audi e-tron, Rivian, etc.) use standard OAT-compatible glycol coolant in their motor/inverter cooling loops. Confirm compatibility with your specific vehicle using the Vehicle Finder.
Q: What is MAP pricing?
A: MAP (Minimum Advertised Price) is Speedteq's policy that protects authorized retailers from below-cost price competition and ensures ArctiFlow products are presented at a price that reflects their quality. All authorized dealers are required to advertise ArctiFlow products at or above the established MAP price. See our full MAP Policy at /pages/map-policy.
Q: Where is ArctiFlow™ manufactured?
A: ArctiFlow is 100% Engineered, Designed, Developed, Tested & Manufactured in the USA at our dedicated manufacturing facility in Peoria, Arizona. No exceptions.
