Additionally, DEX-COOL is specially formulated to interact with aluminum engines, as seen by the differences in composition and color between the two coolants. Using DEX-COOL for an aluminum engine will aid to reduce corrosion, assuming that the car’s previous owner did not use typical green coolant in the vehicle.
What’s the best antifreeze to use in aluminum radiator?
Zerex G05 is the number one antifreeze suggested for all aluminum motors and radiators, and it’s what some 215 folks are using, according to my sources.
What antifreeze is good for aluminum engines?
However, because of some concerns with the interaction of organic coolants with lead solder, using OAT in a copper radiator is not suggested. If your radiator is aluminum, clean your whole cooling system with water and then refill with a 50/450 or 60/40 combination of OAT, you should be OK.
Is Dex-Cool corrosive?
The cooling system of most General Motors automobiles and light trucks has been plagued by corrosion and clogging for ten years. Car and truck owners have complained that Dex-Cool causes chronic overheating and engine damage, while also corroding and clogging the cooling system of their vehicles, and that the coolant has caused rust to form on the cooling system’s internal components.
What is Dex-Cool used for?
The cooling system of most General Motors automobiles and light trucks has been plagued by corrosion and clogging for ten years. Car and truck owners have complained that Dex-Cool causes chronic overheating and engine damage, while also corroding and clogging the cooling system of their vehicles, and that the coolant is toxic.
Does antifreeze react with aluminum?
It has been observed that when a coolant is applied, particularly if it includes nitrites, it has a proclivity to react with unpassivated or unoxidized aluminum. The development of precipitants as a result of this reaction might cause tiny orifices in the cooling system to get clogged.
Does antifreeze corrode aluminum?
Some forms of antifreeze can corrode aluminum cooling system components, hence it is important to use antifreeze that has been specifically designed for aluminum cooling system components when this metal is present. When the pH of the coolant rises over 9.0, aluminum corrosion becomes more pronounced and severe.
Is Peak antifreeze good for aluminum?
All cooling system metals, including aluminum, are shielded from the destructive effects of rust and corrosion. Compatibility with other hybrid gold antifreeze/coolant formulations is not guaranteed.
Is green coolant safe for aluminum?
Their Zerex Original Green coolant contains ethylene glycol, which is suitable for use in both aluminum gasoline engines in passenger cars and heavy duty diesel engines in trucks if you own a fleet of vehicles.
Is Dex-Cool propylene glycol?
Organic Acid Technology, often known as OAT, is a cooling system used in automobiles that uses propylene glycol, which is commonly referred to as Dex-Cool in General Motors cars. Dex-Cool was first developed by General Motors in 1995.
Why is Dexcool bad?
When the coolant level falls below a certain level and oxygen is allowed to enter the system, acid buildup and rust are more noticeable in cooling systems that employ Dexcool. The acid eats away at the gaskets in the head and the intake manifold. In the system, rust accumulates and interferes with coolant flow, resulting in overheating as a result.
Is Dexcool still a problem?
GM continues to utilize Dex-Cool coolant, and there is no longer a concern with the coolant interfering with the gasket. DexCool is, in fact, the approved coolant for GM engines, unlike what some people believe. In addition to the 3.1 and 3.4-liter engines, additional DexCool engines have been noted to have difficulties.
Is Dex cool better than antifreeze?
In spite of the fact that GM continues to employ Dex-Cool coolant, the company has resolved the issue of gasket coolant contact. DexCool is, in fact, the approved coolant for GM engines, despite what some people think. Beyond the 3.1 and 3.4-liter engines, shops have noticed various issues with DexCool engines.
Is Prestone antifreeze good for aluminum engines?
Any nitrite-free HD Organic Acid Technology (OAT) coolant is compatible with Prestone ® HD 50/50 Prediluted NITRITE FREE Extended Life (ELC) Antifreeze/Coolant, and it is recommended for use in any diesel-powered commercial vehicle or stationary engine that contains aluminum or other engine metals.
When did GM stop using Dex-cool?
Dex-Cool, which is manufactured by Texaco, is being utilized solely by General Motors in various 1995 buildout models as well as all 1996 cars and trucks, with the exception of Saturn and Geo vehicles.General Motors (GM) delayed the deployment of Dex-Cool in Saturn vehicles until the 1997 model year because the company did not have enough data to make use of the new coolant practicable in the 1996 model year.
Can you use universal antifreeze with Dexcool?
Chevrolet uses Dex-Cool, which is manufactured by Texaco, in some of its 1995 buildout models, as well as all 1996 vehicles and trucks, with the exception of Saturn and Geo. GM delayed the introduction of Dex-Cool in Saturn vehicles until the 1997 model year because the company did not have enough data to make use of the new coolant practicable in 1996 models, according to the company.
What is the difference between DEX COOL and regular coolant?
In order to identify DEX-COOL coolant from other forms of coolant, the manufacturers usually color the coolant in a distinct hue from the other types of coolants. When it comes to color, DEX-COOL is often orange or red, whereas conventional coolant is typically green.
