One thing to keep in mind on this one is that it is not a premixed aka pre-diluted formula, so you do need to mix in water with at a ratio. So one 1 gallon bottle will net you 2 gallons of coolant. Make sure to use distilled or demineralized water for optimal results. The reason you may want to consider G13 Antifreeze for your Audi or VW is that this coolant formula has been tested with the alloys used in the VW engine, thermostat, radiator, heater core, etc and may not have been fully tested with North American generic.

The K-Seal product here is a little different than our other options. A great way to sidestep a costly repair bill from your auto mechanic, the K-Seal formula is an easy fix you have a coolant leak issue.

No need to drain or flush, just add this to your antifreeze and it will fix all your cracks and leaks in head gaskets, cylinder heads, heater cores, water pump casings, and other cooling system components. It is compatible with most other antifreeze brands. Once a crack or leak has been located, microfibers in the formula instantly begin to mesh together and seal the gap.

This repair holes down to a minuscule size of 0. The result? A permanent seal that is able to withstand high pressures. Valvoline MaxLife is a universal antifreeze and coolant that is ready to use as is pre-diluted. Apart from protecting your vehicle from extreme temperatures, Valvoline MaxLife also lubricates your gaskets and seals, and will work for all makes and models of vehicles.

This particular option comes pre-diluted with distilled water, which will save you a step. It has a super long life, and should be on the longer end of lifespan for an antifreeze. This specific type of antifreeze is engineered to be used in Toyotas, but it also works with the Lexus and Scion family of vehicles.

Next up in our list is a product from Honda and one of the best coolants money can buy. This is a genuine OEM fluid, the same fluid that a brand new Honda vehicle comes loaded with.Regular antifreeze is composed of water mixed with methanol and ethylene glycol. These products are mixed and placed into your cars engine to allow higher boiling points to prevent your car from overheating. With respect to regular coolant, the green color is utilized to interact with rust and corrosion, letting you know visually when the coolant inside your vehicle needs to be replaced.

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. While traditional green coolant is designed to change color due to corrosion, it does not change color due to corrosion occurring in aluminum engines.

As a result, your aluminum engine will continue to corrode without a change in coolant color. Due to the structural differences between DEX-COOL and regular coolant, it is important not to mix the two types of coolants in your car.

Mixing can cause sludge to form and potentially lead to engine failure. If you are looking to switch between the two coolants, you will have to wait until the original coolant is thoroughly flushed through the engine. As a result, you may have to stay with one coolant for the duration of your engine's life.

Advanced Search. Forum A-Body. Results 1 to 1 of 1. Thread Tools Show Printable Version. I've done a bit of research on this, and put together what I found. Which A-bodies came with DexCool from the factory? There may have been some late models with DexCool, but this has not been verified. Differences between green coolant and DexCool There is remarkably little difference between the green antifreeze and DexCool.

Both are ethylene glycol-based. GM claims tap water is suitable for DexCool, but why introduce unnecessary minerals to your engine? The differences rest in the type of corrosion protection each product offers. Green coolant uses a silicate-based corrosion inhibitor that coats the metal. Over time, these inhibitors break down, requiring a coolant flush every 30k miles or so.

In an aluminum engine, green coolant does not change color when it breaks down; so many owners have no idea when this has actually occurred until their nice expensive aluminum heads have cracked. In an iron block engine, green coolant will turn reddish-brown with rust when its corrosion inhibitors break down. However, DexCool does not coat metal components as much as green coolant does, so proper levels must be maintained to ensure corrosion protection. Because corrosion protection does not diminish over time with DexCool, it can be left in the engine much longer than green coolant.

Finally, as a side note, DexCool, being an ethylene glycol-based mixture, is just as toxic as green coolant. I've heard people say that DexCool was created to be less toxic to animals and humans, but this is not true.

DexCool: pros and cons Because DexCool does not coat the metal, in cast iron engines when the coolant level gets low, the iron will start to rust, which mixes with the coolant and creates chunks of gel flowing through the engine. In aluminum engines, if the DexCool level gets low, the aluminum will corrode and weaken, leading to gasket failures or worse.

If you properly maintain your car, you shouldn't have low coolant levels, and thus shouldn't have this problem. A lot of the horror stories we hear stem from improper maintenance improperly mixing DexCool, letting it get low, etc.

DexCool does NOT eat gaskets, as the tale goes. Gasket failures are the result of poor maintenance, old age, or poor design. Whether it is used in an aluminum or cast iron engine, DexCool enjoys much longer protection against corrosion compared to green coolant.

It's also been found to be easier on coolant system components, such as heater cores, radiators, and water pumps. The reason you'll need to eventually change the coolant is not because of corrosion protection breaking down, but because the coolant thickens with deposits.Do you know how antifreeze works?

Best Antifreeze: Keep Your Engine Cooler for Longer

This is ethylene glycol based formula that is without phosphate and silicate is especially formulated for Audi cars for almost any model. It can also protect aluminum parts. Once it gets mixed up with 50 percent water, the solution goes up to work efficiently.

This is basically a genuine concentrated formula formulated exclusively for Audi vehicles on almost all models.An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments.

Common antifreezes increase the boiling point of the liquid, allowing higher coolant temperature. Because water has good properties as a coolantwater plus antifreeze is used in internal combustion engines and other heat transfer applications, such as HVAC chillers and solar water heaters. The purpose of antifreeze is to prevent a rigid enclosure from bursting due to expansion when water freezes.

Commercially, both the additive pure concentrate and the mixture diluted solution are called antifreeze, depending on the context.

Careful selection of an antifreeze can enable a wide temperature range in which the mixture remains in the liquid phasewhich is critical to efficient heat transfer and the proper functioning of heat exchangers. Secondarily but not less importantly, most if not all commercial antifreeze formulations intended for use in heat transfer applications include different kinds of anti-corrosion and anti- cavitation agents that preserve the entire hydraulic circuit from progressive wear.

Water was the original coolant for internal combustion engines. It is cheap, nontoxic, and has a high heat capacity. These problems are addressed by the development of alternative coolants with improved properties. Freezing and boiling points are colligative properties of a solution, which depend on the concentration of dissolved substances. Hence salts lower the melting points of aqueous solutions.

Salts are frequently used for de-icingbut salt solutions are not used for cooling systems because they induce corrosion of metals.

Low molecular weight organic compounds tend to have melting points lower than water, which recommends them as antifreeze agents. Solutions of organic compounds, especially alcoholsin water are effective. Alcohols - ethanol, methanol, ethylene glycol, etc. The term engine coolant is widely used in the automotive industry, which covers its primary function of convective heat transfer for internal combustion engines.

When used in an automotive context, corrosion inhibitors are added to help protect vehicles' radiatorswhich often contain a range of electrochemically incompatible metals aluminumcast ironcopperbrasssolderet cetera. Water pump seal lubricant is also added. Antifreeze was developed to overcome the shortcomings of water as a heat transfer fluid.

On the other hand, if the engine coolant gets too hot, it might boil while inside the engine, causing voids pockets of steamleading to localized hot spots and the catastrophic failure of the engine. If plain water were to be used as an engine coolant, it would promote galvanic corrosion. Proper engine coolant and a pressurized coolant system obviate the shortcomings of water. Early engine coolant antifreeze was methanol methyl alcohol. Ethylene glycol was developed because its higher boiling point was more compatible with heating systems.

The most common water-based antifreeze solutions used in electronics cooling are mixtures of water and either ethylene glycol EGW or propylene glycol PGW.Got car issues? Well, we've got the answers! Easily search thousands of entries to find exactly what you're looking for.

Be sure to leave a comment or question on anything that may interest you. You can also send an email to our pro for direct assistance! So you discovered you need to add some antifreeze.

The hang up came when you headed to the auto parts store a found a surprising variety of antifreeze options in front of you.

We can debate whether or not that is true in another article, but for us, that means there are even more varieties and classes of antifreeze available for your vehicle. Luckily the manufactures of these new and different antifreezes have continued to make them different colors so they are easily identifiable. If you plan on keeping your car for the rest of its useful life, the surefire way to make sure you pick the right kind of antifreeze that your vehicle needs is to go to the dealership and purchase some directly from the manufacturer.

Some such situation where this is a good idea is newer Ford vehicles with a gold color antifreeze, or GM vehicles that came with Dex-Cool. This option will also most likely be the most expensive option you have available, and there may be an off the shelf antifreeze you can use just as easily without harming your vehicle and save some money.

Low coolant levels can cause immediate damage while the wrong type or mixed coolants will take a long time to cause problems. There are 3 basic types of antifreeze used today, ethylene glycol based, propylene Glycol based and the newer Organic Acid Technology.

The biggest thing to look out for is using the organic acid technology OAT in older vehicles with brass or copper radiators. OAT antifreeze is designed to be used to protect aluminum components from corrosion in newer cars with aluminum radiators and heads. OAT antifreeze may not do as good of a job preventing corrosion of brass or copper.What is the best coolant for a Mustang engine running in a Ford.

If so, is it worth the extra cost? My Toyota Higlander says flush atmiles Thanks for your help.

Back in they only had ethylene glycol antifreeze — the green stuff. The mix was standard. You have no reason to use anything else. The flush interval for my car is every 90, miles or three years. With old style antifreeze I believe the recommended change interval is every 2 years or 24K miles. Is there any reason to use the old style antifreeze, ethylene glycol?

I understand it can turn to a gel hence the 2 year flush interval. Get some Zerex Original Green unless you have an aluminum radiator or heater core. Even if you do, the Green will work. If you do have aluminum, I would suggest their G G is a Ford formulation used in their engines with mixed ferrous and aluminum engines and cooling systems.

Which Antifreeze Color Should I Use?

With any coolant, changing the coolant every two years cheap compared to ruining the stuff it comes in contact with. Mix the coolant with tap water if it is not hard. If you have a lot minerals in your tap water, do your final fill with coolant and distilled or deionized water.

The silicates are what causes the gelling problems so reducing them reduces the gelling. Note that the silicate is there because it is a corrosion inhibitor. They mix in others as well. Last I knew, all manufacturers fill their vehicles with ethylene glycol-based coolants and disrecommend propylene glycol. Use what ever is on sale at Wal-Mart and it will be 5 times as good as what Ford originally put in your which apparently survived all these years with God-knows-what in the cooling system….

Gelling of a coolant system occurs when too high of a concentration of antifreeze to water is used. Daver July 4,pm 1. SteveF July 5,pm 2. NYBo July 5,pm 3. Daver July 5,pm 4. Beadsandbeads July 5,pm 5. Caddyman July 5,pm 6. Tester July 5,pm 7.
