Tap water or well water is not recommended due to the minerals in the water. For temperatures below that, up to 70% coolant concentrate can be used. From concentrate, most of the time a 50 percent coolant and 50 percent distilled or de-ionized water dilution is recommended.This will protect the system from freezing to about -34 F. Which could then lead to an expensive doctors bill. Check the owners manual.įirst, check to make sure the solution of coolant/antifreeze you buy is not already pre-diluted. Mixing the wrong types could cause radiator and cooling system damage (which could lead to engine/waterpump damage) and a repair bill that’ll make you pass out on the floor. Unless you’re an expert on the exact chemical composition and reactions of the various types, keep it simple and stick with what the manufacturer recommends. For example, Toyota has green and red, but it depends on the year and model of the vehicle as to which kind is needed. Various aftermarket companies and vehicle manufacturers use different colors. You can also check with your (manufacturer) dealership parts department. Check in your owners manual to see exactly which type of coolant to add to your vehicle. However just because it’s the same color doesn’t necessarily mean it’s the same type. Typically orange or yellow.Īs a quick guide, if your topping up the coolant levels, use the same color as is in the vehicle already. This has silicates and has an extended life lasting up to 5 years. Hybrid Organic Acid Technology (HOAT)- A mix of the above two types of coolant.Provides high-temperature protection for aluminum. Organic Acid Technology (OAG)- Found in most newer cars, does not contain silicates or phosphates but has azoles and neutralized organic acids (corrosion inhibitors).Lasts around 2 years. Usually bright green. Inorganic Acid Technology (IAG)-Typically used in older cars up until the mid-90s in the U.S, contains phosphates (corrosion inhibitors) and silicates.It’s that much cheaper and your car will be fine.Coolant colors yellow and red 3 main types of coolant It’s my opinion that yes, you should buy a gallon of this stuff. Super Tech’s 50/50 coolant meets and exceeds cooling and boiling point requirements for most modern engines, is priced well, and has some favorable reviews. According to 42 reviews on, Super-Tech’s 50/50 coolant has 4.5 stars out of 5. Not only does Peak and Prestone boast these standards, so does Super Tech’s coolant.īut don’t take my word for it. Any self-respecting coolant advertises ASTM D3306 and ASTM D4985 as standards for Glycol Base Engine Coolant for Automobile and Light-Duty Service and Standard Specification for Low Silicate Ethylene Glycol Base Engine Coolant for Heavy Duty Engines. ![]() Super Tech’s coolant does the same.įinally, the governing body for coolant is the American Society for Testing and Materials. Universal coolants use unique OAT-based corrosion packages with proprietary organic acids (such as carboxylate) to provide broad spectrum protection.īoth Prestone and Peak, two of the most popular brands of Coolant raise boiling points of water to 265F and lowers the boiling point to -34F. Coolant must interact well with these materials.Īccording to Walmart’s description for Super Tech 5050 Antifreeze coolant, this coolant is In addition, many components attached to engines are plastic. Most modern engines today don’t have iron blocks anymore and have lighter aluminum blocks. ![]() With that out of the way, most of the concerns people have with any value-brand coolant is if it’s safe for their engine’s and does it meet the heating and cooling requirements for your area (if you live in a hot or cold climate.) Why is Chevron with Techron more expensive & is gas with Techron worth the extra cost? - Alt Car news
