How to choose the right antifreeze for your car?
Choose Organic Acid Technology (OAT) antifreeze whether you buy a Toyota, Honda, GM, or some other recent model with an aluminum radiator. If you have an Asian or European car, you can use Hybrid Organic Acid Technology (HOAT) Antifreeze. When it comes to antifreeze specifications, diesel engines vary from petrol engines.
What kind of antifreeze do you put in a Honda Civic?
Prestone Antifreeze The Prestone brand of antifreeze also works well in Honda Civics and is a good alternative to genuine Honda antifreeze because it helps prevent corrosion and rusting. You can purchase Prestone antifreeze at an auto shop or at some larger department stores in the automotive department.
Which antifreeze is safe for aluminum?
Ethylene glycol-based coolants are safe for aluminum when diluted with distilled water.
Does antifreeze corrode 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 green antifreeze good for aluminum radiators?
The original glycol-based “green” antifreeze we are all familiar with. They have quick-acting silicate and phosphate corrosion inhibitors that do a good job inhibiting corrosion on both iron and aluminum surfaces.
Is Prestone antifreeze compatible with 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.
Is antifreeze corrosive to metal?
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.
Does glycol corrode 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 known that impurities often found in ethylene glycol/water mixtures, such as ferric, copper, and chloride ions, can accelerate this corrosion.
What's the difference between yellow and green antifreeze?
Usually (but not always) dyed orange or yellow so you could tell the difference between OAT and IAT, this coolant has similar corrosion protection as the green stuff, however they are designed to be slower acting, hence the extended-life moniker.
What antifreeze is silicate free?
OAT antifreeze has a replacement interval of 150,000 miles or generally 5-7 years, and depending on the make, is either silicate free, phosphate free, or both. OAT antifreeze began in the American market with GM's introduction to Dexcool Orange in 1994.
Does Peak antifreeze contain silicates?
PEAK Antifreeze + Coolant is free of 2-EHA, silicate, nitrate, borate, and amines, ensuring maximum cooling system performance for 10+ years/300,000+ miles*. It is compatible for use with any color or type of antifreeze/coolant in the system.
Is Peak antifreeze phosphate free?
It contains high-quality organic acid corrosion inhibitors and is free of borate, nitrite, nitrate, phosphate, silicate and amines chemicals.
Is universal antifreeze safe?
Even so, universal coolants are formulated to mix with virtually any coolant. The makers of these product say their antifreeze can be safely used in any year, make or model of vehicle.
What is green antifreeze used for?
Green antifreeze is made with special tweaks to the formula specifically to help prevent the corrosion of metals in a vehicle's cooling system. That older formula is typically meant for vehicles made before the year 2000, which were built with more steel and copper components than modern vehicles.
How long does antifreeze last?
The maker says that since the product is a real OEM, so it will last for two years.
What is antifreeze in a radiator?
Antifreeze is a liquid that prevents the engine from overheating in both hot and cold conditions. Antifreeze liquid is usually a combination of water and glycol compounds that serve as lubricants and anti-corrosion products to hold your aluminum radiator in good working order.
What is universal coolant?
Universal coolants, also known as 50/50 pre-mix coolants, are a form of universal coolant. This is because they produce 50% demineralized water. As a result, there is no need to dissolve the solvent before using it. Universal coolants provide a low silica content to shield the engine and radiator from corrosion.
What are non toxic additives?
Non-toxic additives that resist degradation of the vehicle’s cooling system include silicates, phosphates, and propylene glycol. Other factors to consider: Always take into account the engine type – petrol or diesel; Check what your car requires – propylene glycol or ethylene glycol based antifreeze;
Can you mix 50/50 water with coolant?
Tips for users: combine it with 50/50 water and coolant, as any other mixture can make your car freeze or overheat faster. The advantage of this is that you do not have to buy 50% water in the package. However, if you buy 1 gallon of condensed coolant, you can get 2 gallons of the RTU coolant. Pros.
Can you mix antifreeze and coolant?
They used to be two different liquids in separate bottles – the antifreeze was mixed with the coolant or water in the car’s radiator to cool it down. But contemporary products include both antifreeze and coolant liquids in the same bottle relieving you of the hassle of mixing them yourself.
What coolant does Volvo use?
Volvo transitioned to Glysantin G48 coolant at the end of the 90s and replaced it with G64 PSi-OAT coolant.#N#G48 is a medium-silicate and borated coolant with organic additive (2EHA). it replaced the many varieties of blue colored IAT coolants that were in circulation. It also effectively replaces G05 after the latter was dropped from MB 325.0#N#almost any dark blue colored coolant for sale in the world will be G48 or a locally produced variant meeting spec. some variants such as paraflu 11 and nulon green LL will contain nitrites, and sodium benzoate but the genuine glysantin/volvo coolant does not.
What are the different types of coolants?
There's only three kinds of coolants out there: IAT, HOAT, and the OAT's. IAT are obsolete, long since abandoned by OEM's due to their short service life and tendency to participate out silicate, HOAT (aka G-05) are a little newer but also now largely obsolete and abandoned.
Did Volvo aluminum 6 cylinders leak?
What he said. Back in the late nineties there were real issues with Volvo Aluminum 6 cylinder blocks leaking after a few years. It was later found that people were not using the recommended coolant from Volvo. These non Volvo recommended coolants were literately eating through the Aluminum blocks.
Is G05 a good coolant?
If I was switching over a generic cooling system, I prefer P-HOAT (asian) as they're more readily available, but G05 is another good HOAT coolant. Both should be safe to use in any aluminum engine / cooling system.
What is Dexcool radiator?
Dexcool is for all iron/aluminum cooling systems and most cars use a brass radiator and/or brass heater cores. If you use an aluminum heater core and alum radiator then it is alright. I use CAT (Caterpillar brand) Extended life and Texaco extended life antifreeze in everything for quite a few years and I still have almost all the cars I had from the mid '90s and still running without any problems ever still using the same Texaco and CAT extended life. Ground the engine good but I have seen on many Caterpillar diesel engines where the ground wire was attached to the aluminum T-stat housing causing severe electrolysis eating the aluminum up (also in the aluminum water pump if grounded there). It is simple to prevent though. NEVER let the radiator be the engine ground through the coolant. BAD BAD BAD!
Does drinking water oxidize aluminum?
Also, if your using well, city, etc, drinking water, you have a lot of iron (as ions) in the water. These ions will want to oxidize the aluminum (for chemical reasons I wont go into) and eat away your aluminum. Also, with drinking water, you make your cooling system fluid electrolytic, which means if the engine block has a better ground through ...
Why do coolants have a term on life?
The reason coolants have a term on life is because that is how long the inhibitor package will last. Remember this, it has nothing to do with the color of the coolant when determining the condition of the inhibitor package. When the inhibitor package decays you no longer are protected from minerals eating the aluminum.
How often should I replace coolant?
Just pour it in and forget it. I recommend getting a five-year coolant and replacing it every three years to be safe.
Why do old copper radiators spoiled us?
The older copper radiators spoiled us because they were so forgiving with these minerals. Old timers will have a tough time with this water requirement because they have used all types of water without any problems in the past. The solution to this water problem is simple, do not purchase the concentrated coolant.
Does aluminum radiator water protect?
By Tom DeWitt. 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. Concentrated coolants create a potential problem because this lets the installer choose ...
