AMSOIL Antifreeze & Coolant


Amsoil AntifreezeAMSOIL Antifreeze & Coolant (ANT) is formulated to provide benefits far beyond those found in today’s conventional antifreeze and coolant products. This revolutionary formulation provides maximum antifreeze and cooling protection in the most extreme temperatures and operating conditions. And unlike conventional ethylene glycol based products, which are highly toxic and even fatal, AMSOIL Antifreeze & Coolant is formulated with propylene glycol. It is biodegradable and requires no special disposal costs or procedures in most areas. Above all, its low toxicity limits the threat to children, pets or wildlife.

AMSOIL Antifreeze & Coolant provides even greater benefits:

Lasts Longer
AMSOIL Antifreeze & Coolant contains a proprietary poly organic acid technology. It eliminates the need for supplemental coolant additives and recharging cooling systems. AMSOIL Antifreeze & Coolant provides extended service life in all gasoline and diesel vehicles. It can be used for seven years or 250,000 miles in passenger cars, light-duty trucks, vans and recreational vehicles. It lasts seven years or 750,000 miles in over-the-road diesel trucks. Also for motorcycles, ATVs, snowmobiles and closed marine applications. AMSOIL Antifreeze and Engine Coolant lasts longer than conventional products.

Compatible With Other Fluids
AMSOIL Antifreeze & Coolant is dyed neutral yellow and is compatible with all ethylene and propylene antifreeze and coolant formulations on the market, including DEX-Cool®, Sierra® and Zerex®. It is also compatible with fully formulated diesel antifreezes and other organic acid technology (OAT) and hybrid organic acid technology (HOAT) formulations.

Stops Leaks
AMSOIL Antifreeze & Coolant adheres to metal. It self-seals hairline cracks in welds and seams to prevent leaks, without additional stop-leak products or fibrous materials.

Prevents Metallic Corrosion
Independent tests reveal AMSOIL Antifreeze & Engine Coolant surpassed standards for metallic corrosion. It plates metal to protect even when exposed to acids and salt spray. Standard allowances for loss in aluminum and solder are less than 60 mg. AMSOIL Antifreeze & Engine Coolant lost 0 mg in aluminum and less than 6 mg in solder. Standards for iron, steel, copper and brass allow a maximum loss of less than 20 mg. AMSOIL Antifreeze & Engine Coolant never exceeded a 3 mg loss in any of those metals in a testing period that was run for 10 weeks, three weeks longer than required tests.

Description:
The most common formulation of antifreeze is green in color and uses ethylene glycol as a base with anti-corrosion additives mixed in. The ethylene glycol part of the formula provides crucial anti-freezing characteristics and the additives deliver the anti-rust and anti-corrosion capabilities. Beginning with 1995 models, most GM vehicles started coming from the factory filled with an extended-life antifreeze, trademarked as DEX-COOL®. Distinctively different in appearance, DEX-COOL®, and its aftermarket equivalents, is an orange/amber color. It still uses ethylene glycol as a base, but contains a different additive package than standard green-colored antifreeze. This coolant is designed to protect cooling systems for up to 150,000 miles or five years. Other antifreeze formulations include silicate-free for Japanese cars and phosphate-free for European cars.     

Purpose:
When properly mixed, antifreeze and water provide excellent anti-freeze, anti-boil and anticorrosive properties.

Maintenance Tips/Suggestions:
Check your owner's manual for antifreeze usage specifications. Antifreeze, when mixed at a 50/50 ratio with water, provides excellent anti-freeze, anti-boil, and anti-corrosive properties. In extremely cold environments, the ratio for standard ethylene glycol can go as high as 70% antifreeze, 30% water. With DEX-COOL®, the maximum ratio of antifreeze to water is 60/40. Although DEX-COOL® type antifreeze can be mixed with standard ethylene glycol antifreeze, DEX-COOL® loses its 5 yr./150,000 life. As such, it's best not to mix antifreeze types unless absolutely necessary. All coolants must be diluted with water at the proper ratios and should not be used full-strength. Full-strength antifreeze actually has a lower freeze point than when mixed with water. Generally, standard ethylene glycol type antifreeze should be changed every two years or 24,000 miles. Even though the coolant freeze protection may test OK with a hydrometer (freeze protection only drops with extreme dilution, not with age), the additives break down over time. When changing coolant, it also presents an opportune time to replace bad cooling system hoses. Leaking, brittle, spongy, cracked, or rotted hoses should be replaced before new antifreeze is installed. Hose clamp connections should also be checked to ensure that they're secure and free from leaks. If you decide to service your cooling system yourself, use extreme caution: Opening a hot radiator or coolant reservoir/overflow tank can cause severe burns. Be sure that both the engine and cooling system are cool before you begin any heating/cooling system maintenance or repairs. Because of lower hood profiles and cramped engine quarters, it's also possible that your car may be equipped with an air bleed for the cooling system. Unless the cooling system is bled properly, air may stay trapped in the system and cause erratic temperatures, or in extreme cases, engine or cooling system damage. If you're unsure about any aspect of cooling system service, don't take a chance. Have your car looked at by a professional service technician.
