Prestone MAX Asian Green 50/50 Antifreeze Coolant 1 qt — Premixed with CorGuard for Corrosion Protection

Prestone MAX Asian Green 50/50 Antifreeze Automotive Coolant is a ready-to-use, long-lasting coolant formulated for Asian vehicle cooling systems that helps protect against extreme temperatures and corrosion.

This one-quart bottle of Prestone MAX Asian Green 50/50 comes pre-mixed for convenient pouring—no measuring or diluting required. It includes Prestone's CorGuard technology to help guard metal surfaces inside the cooling system and a bitterant additive to discourage accidental ingestion. The formula is designed to support efficient heat transfer so engines run within their ideal temperature range in both hot and cold climates.

How does this coolant protect my engine in cold and hot weather?

The 50/50 premix balances antifreeze concentrate and water to lower freezing point and raise boiling point compared with plain water. That helps prevent freeze-related blockages in winter and reduces the risk of overheating in summer, allowing the cooling system to maintain consistent operating temperatures.

• Pre-mixed for correct freeze/boil protection out of the bottle
• Formulated to help prevent corrosion on metal cooling system parts
• Helps maintain coolant chemistry for stable heat transfer

Is this product compatible with my Asian vehicle?

Prestone MAX Asian Green 50/50 is specifically formulated to be compatible with many Asian makes that require an ethylene-glycol-based green coolant. Always check your vehicle owner’s manual for the manufacturer’s recommended coolant specification before use.

• Matches common coolant specifications for many Asian vehicles
• Safe for systems that call for ethylene-glycol-based green formulas
• Intended for use where manufacturer permits aftermarket coolant

What maintenance benefits does Prestone CorGuard technology provide?

CorGuard technology helps reduce corrosion and mineral buildup on metal and rubber components inside the cooling system, which can extend component life and maintain system efficiency. Regular use according to service intervals helps keep passages clear so the coolant can circulate properly.

• Helps protect metal parts from rust and electrochemical wear
• Supports gasket and hose longevity by stabilizing coolant chemistry
• Helps cooling system run more efficiently over time

How do I use this premixed coolant safely?

The bottle arrives in a 50/50 mix—pour directly into the coolant reservoir or radiator once the engine is cool. Avoid opening a hot pressurized system, follow proper disposal guidelines for old coolant, and keep the liquid away from children and pets due to the bitterant and toxic properties.

• Use only when engine is cool and system is depressurized
• Pour directly—no dilution needed for most approved applications
• Dispose of used coolant per local hazardous-waste regulations

Who is this for: Drivers and vehicle owners who need a ready-to-use, manufacturer-compatible coolant for Asian cars, trucks, and SUVs that require a green ethylene-glycol formula. It’s suited to DIYers and professional shops looking for a one-quart premixed option with corrosion protection and simple application. If your vehicle manual specifies a different coolant type or color, confirm compatibility before switching products.
