One of the major problems people have with their cars is having their coolant system freeze up in very cold and extreme environments. Once your coolant system freezes, you’ll have to get your car towed, which can be expensive and inconvenient. This is why it’s important to know what type of antifreeze you should use in your car. In this post, I will share with you some of the best car antifreeze that will keep your coolant from freezing and the cooling system lubricated.

What is antifreeze?

Antifreeze is a liquid that is used to cool the heat of a combustion engine. It is typically made of a mixture of ethylene glycol and water. It is important to keep the antifreeze in liquid form at all times. If the antifreeze is not in liquid form, it can freeze and cause damage to the engine. The best way to keep the antifreeze in liquid form is to make sure that it is kept in the proper temperature range. If the liquid is too cold, then it will freeze and solidify. If the liquid is too warm, then the antifreeze will evaporate and the engine will not be protected.

What types of antifreeze are there?

There are many types of antifreeze on the market. However, not all antifreeze is created equal. Some antifreeze is designed for older cars, while others are designed for newer cars. You should also consider the type of car you are buying the antifreeze for. For example, an older car will require a different type of antifreeze than a newer car. If you get antifreeze for a new car, you will want to make sure that the antifreeze is designed for that car. The best antifreeze is the one that is designed for the specific type of car.

What is the best car antifreeze?

Car antifreeze is a liquid that is used to coat the inside of the engine and radiator of a car. This liquid is used to help stop the car from overheating. Car antifreeze is a dangerous substance that can be toxic to humans, so it is important to make sure you use the proper type. The best car antifreeze is a colorless, odorless, and tasteless liquid that is made from a mixture of water and ethylene glycol.

Conclusion

It is important to make sure that your car’s coolant stays in liquid form and away from the freezing point. If your coolant turns into a solid form, it could cause your engine to overheat before the coolant melts and turns into a liquid which could potentially damage your engine. There are many different types of antifreeze on the market, and it is important to make the right choice for your car. Some antifreeze can be harmful to your car’s engine as it depends if your engine is made of aluminum or cast steel. The best type of antifreeze for your car is a concentrate type with a high level of ethylene glycol. This type of antifreeze has a low freezing point and is also good for your car’s cooling system. Another type of antifreeze to consider is water-based antifreeze. This type of antifreeze is safe for both the engine and the cooling system.

The Best

Mopar - Coolant 50/50 Premixed

About this item

  • Package Weight: 4.227 kg
  • Product Type: Auto Part
  • Package Quantity: 1
  • Embittered: Contains Bittering Agent

Already mixed is great and saves time and money on buying distilled water. Keeps the engine running at normal temperatures. If this antifreeze boils, it's probably something that is not right in the cooling system.

Some customers reported that they received the wrong product, or it was damaged and leaking. Again, where are the packaging, shipment, and quality control?

Our Thoughts - A great product that can be used on a large variety of gasoline and diesel engines.

Very Good

Engine Ice - High-Performance Coolant

About this item

  • Engine Ice hi-performance coolant is biodegradable, phosphate-free, and non-toxic, typically reduces operating race temperatures and effectively keeps
    boil-over temperatures to 256° Fahrenheit or less and freeze-up protection to -26° Fahrenheit
  • With an average reduction in operating temperatures of 10° Fahrenheit - 20° Fahrenheit Engine Ice is perfect for racing or street, motorcycle or auto, ATV or snow machine
  • Engine Ice hi-performance coolant is legal in CCS and ASRA road racing and permitted at many tracks around the world. Easy to Use – Premixed with deionized water for out-of-the-bottle use.
  • Engineered to keep your operating temperatures at optimum performance to not lose power through excess heat; Engine Ice is safe for aluminum and almost all metals
  • Uses propylene glycol, which has been proven to eliminate water pump gasket and seal failures; it has also been shown in high-load, high-stress conditions to reduce operating temperatures more than standard coolants

A more natural antifreeze/coolant than others. Uses propylene glycol rather than ethylene glycol.

Again, customers reported that the packaging and quality control needs improvement. Containers leaked and the packaging was ripped. A bit pricy.

Our Thoughts - A great product that can be used on multiple types of engines. No phosphates mean fewer toxins.

Very Good

ACDelco - GM Original Equipment, Pre-Mix Engine Coolant

About this item

  • Specially formulated for long service intervals, the coolant can last up to 5 years or 150,000 miles. (Maintenance needs vary with different uses and driving conditions. See your Owner's Manual for more information)
  • Provides effective long-term anti-corrosion support by protecting brass, cast iron, steel, solder, and copper components. Also provides superior high-temperature protection for aluminum components.
  • Non-silicate formula retains excellent heat transfer characteristics for improved water pump life
  • Long shelf life: storage-stable for 8 years
  • The backward compatible formula can be used with conventional cooling systems and may also be used for service of all 1994-95 GM vehicles EXCEPT 1994 Cavaliers/Sunfires with 4-cylinder engines. Must be replaced every 2 years/30,000 miles whenever used in a vehicle not originally designed to use Dex-Cool

Works with the majority of vehicles, whether it's gasoline or diesel.

Again, customers reported that the quality control needs improvement.

Our Thoughts - A great antifreeze/coolant for a reasonable price. It will last for years without replacing it with a new coolant. Always check the owner's manual to make sure you purchase the correct coolant.

Zerex - DEX-COOL, Concentrate Antifreeze/Coolant

About this item

  • UNSURPASSED FREEZE PROTECTION AND ANTI-BOIL PERFORMANCE outperform industry standards
  • ORGANIC ACID TECHNOLOGY RESISTS RUST, scale, and CORROSION while protecting all cooling system metals (including aluminum)
  • HIGH-QUALITY ADDITIVES PROTECT AGAINST LEAKS and won’t harm gaskets, hoses, plastics, or original vehicle finish
  • ORANGE CONCENTRATE FORMULA should be mixed with clean tap water or demineralized water at a 50/50 ratio for temperatures -34 to 265F; 60/40 for -62 to 270F; and 70/30 for -84 to 267F

Some customers prefer to mix the antifreeze/coolant themselves. It will prevent corrosion from moisture buildup in your cooling system.

Customers reported that the quality control needs improvement. The container was full of water, not antifreeze. The container had the cap seal open.

Our Thoughts - A good quality antifreeze/coolant that will keep your vehicle's coolant from freezing when parked outdoors.

Good Value

Valvoline - Engine Coolant / Antifreeze

About this item

  • Recommended for use in all makes, all models, all mileages, and compatible with all colors
  • Only antifreeze contains Alugard Plus, a special additive that allows these chemistries to work together to provide maximum protection
  • Lubricates gaskets and seals
  • Helps protect against cold weather freeze-ups and hot weather boil-overs
  • Contains 30 – 50 ppm of denatonium benzoate as a bittering agent.

It comes already mixed, it saves time, and no need to buy distilled water.

Packaging and shipment need improving. Customers reported the packaging was damaged and the container was leaking.

Our Thoughts - This is a good antifreeze/coolant, with only a few niggly packaging issues that annoy people.
