The key to maximizing the life of an aluminum radiator is not so much the coolant brand as it is the water type. All coolants sold today will protect the aluminum radiators adequately however distilled water must be part of the package.
Is antifreeze corrosive to aluminum?
Aluminum cooling system components can be corroded by some types of antifreeze, therefore antifreeze engineered for aluminum components should be used when this metal is present. Aluminium corrosion accelerates when the coolant pH reaches levels higher than 9.0.
Is ethylene glycol safe for aluminum?
The corrosion of aluminum alloy in the presence of ethylene glycol is most likely a result of acidic attack by these acids. … It is not generally recommended to use uninhibited ethylene glycols for heat transfer applications.

What antifreeze is silicate free?Conventional green antifreeze was recommended by most American original equipment manufacturers (OEM) for over 70 years. OAT (Organic Acid Technology) Propylene glycol based antifreeze that is silicate-free with the same metal wear protection as IAT antifreeze.
Article first time published onDoes propylene glycol corrode aluminum?
Aluminum tends to be susceptible to corrosion, or pitting, from impurities in unpurified water. Even with a glycol solution in distilled water, both ethylene glycol and propylene glycol form acidic compounds under oxidation. This becomes corrosive on wetted surfaces and forms organic acid byproducts.
Is Dex cool good for aluminum?
In addition to the specific composition and color of the two coolants, DEX-COOL is designed specifically to interact with aluminum engines. Unless a previous owner has used traditional green coolant in your vehicle, using DEX-COOL for an aluminum engine will help minimize corrosion.
What is an aluminum radiator?
They also used thinner material to cut weight and improve heat transfer but the longevity suffered. Aluminum radiators are welded or “aluminum brazed” and the finished piece is 100% aluminum. This eliminates the dissimilar metals and solder bloom problems that affect copper radiators.
Is all antifreeze ethylene glycol?
Most antifreeze/coolants contain ethylene glycol (EG) – a slightly sweet smelling chemical that is poisonous to animals and humans. Propylene glycol (PG), which is less hazardous, is also used. Both are still toxic when drained, and should be disposed of properly.
Is Prestone coolant good for aluminum radiators?
Prestone Dex-Cool® Extended Life Antifreeze/Coolant recommended for all vehicles that require DEX-COOL® coolant, and other cars and light-duty trucks with aluminum radiators to help combat harsher weather. Available in both concentrated and 50/50 Pre-diluted formulas.
Who makes Peak antifreeze?
Old World Industries, LLC. U.S. Old World Industries (OWI) is an American automotive and chemical company best known for their PEAK brand of motor oil, antifreeze and other automotive products. The company markets itself as an “independent, family-owned business”.
What happens if you use the wrong color antifreeze?
If you do mix different-coloured coolants they generally do not mix well and some can form a gel-like substance. This will halt coolant flow, causing blockages that can lead the engine to overheat, as well as damage to the radiator, water jackets and heater core. Also, the water pump can overheat and fail.
Does brand of antifreeze matter?
The truth is, color is not a reliable predictor for what type of coolant you have. … Then the older IAT coolant is green. Coolants that manufacturers sell can confuse matters even more, like Honda’s blue coolant. That’s why you need to read what the bottle says and and not rely specific color you’re pouring.
When did GM stop using Dex cool?
Dex-Cool, which is made by Texaco, is being used exclusively by General Motors in some buildout 1995 models and all 1996 cars and trucks except Saturn and Geo. GM postponed using Dex-Cool in Saturn cars until the 1997 model year because it did not have enough data to make use of the new coolant possible in 1996 models.
Can I mix Prestone with Peak antifreeze?
If you’re looking to change your coolant, make sure you flush your radiator system a couple of times and then add Prestone (or any other regular coolant). Never run both of them together.
Can I use Prestone instead of Dex cool?
Yes. Prestone’s Coolant/Antifreeze is guaranteed to be compatible with all cars, vans or light trucks. Thanks to its unique and patented formula, Prestone Coolant/Antifreeze remains the only coolant on the market that can be mixed with another product within the cooling system without causing damage.
What color is peak coolant?
PEAK® Antifreeze + Coolant is a conventional (green), ethylene glycol based antifreeze for use in older automotive and light duty diesel applications.
Is Prestone safe for aluminum engines?
Prestone ® HD 50/50 Prediluted NITRITE FREE Extended Life (ELC) Antifreeze/Coolant is intended for use and compatible with ANY nitrite free HD Organic Acid Technology (OAT) coolant in ANY diesel-powered commercial vehicle engine or stationary engine with aluminum or other engine metals. …

Can you mix Dexcool with green antifreeze?
Today, there are two: The green coolant and the orange colored coolant, which is also known as Dexcool. Let’s look at these more closely. The green coolant is an inorganic additive technology (IAT). … The two coolants should never be mixed together as they do not react well.
Can I use Dex Cool antifreeze in a Toyota?
NO IT’S NOT! Toyota Red doesn’t contain silicon or silcates, whereas regular green does. Don’t use Dexcool, or if you do, flush it like it was normal antifreeze, as it will get muddy after extended use.
What is green antifreeze?
Why is Antifreeze Green? If antifreeze is green, that probably means it was made from an older formula that uses something called Inorganic Additive Technology. Green antifreeze is made with special tweaks to the formula specifically to help prevent the corrosion of metals in a vehicle’s cooling system.
What is green antifreeze used for?
Green engine coolants are designed for use in older cars (think pre-2000), ones that contain a lot of steel and copper components in the cooling system. To protect these metallic parts from rust and corrosion, Inorganic Additive Technology (IAT) gets added to the mix.
What is the red antifreeze?
Red antifreeze is commercially known as Dexcool® that lasts longer than other types of antifreeze. … This hybrid technology leads to the production of red antifreeze. When compared with green antifreeze and other older versions of antifreeze compounds, red antifreeze is more stable and it improves the water pump life.
Does antifreeze stop corrosion?
It provides protection from rust and corrosion and does not harm rubber hoses and plastics. Antifreeze should not corrode metal parts, attack rubber, become viscous at low temperatures, or evaporate readily at the ordinary engine operating temperature.
