What Kind Of Coolant Do I Need For My Mercedes – It seems that we are often redirected to a forum link or told that the Subaru dealer states something other than what is stated in the owner’s manual.
I can tell you that just like software update after software update as a result of something learned about off-road behavior, Subaru will address things that come up that can negatively impact ownership. This is especially true when Subaru changed the oil change requirements to keep the warranty on all Turbo models at 3,750 miles instead of the Fantasy, the 7,000 oil change interval that was printed in the owner’s manual. Some Subaru dealers actually suggest cooling system services that differ from what Subaru printed in the manual, I think they are right about that.
What Kind Of Coolant Do I Need For My Mercedes
I will try to explain which coolant is right for your Subaru at this time.
Everything You Ever Needed To Know About Antifreeze And Coolant
If you own a 1990 to 2002 2.2L DOHC or a 1995 to 1999 2.5L DOHC, you can use almost any type of common green antifreeze/coolant. No need to add any type of leak, I mean coolant conditioner, service interval is every 30,000 or about every 2 years on average. This will apply in most Subaru Outback, Impreza, Forester, Legacy and WRX models.
If you own a 1999 to 2008 SOHC 2.5L, you should use the O.E. Subaru Long Life Coolant, which is green in color in the picture below. If you did not have the head gaskets replaced or if you did not have them replaced at the dealer, you should also use a cooling system conditioner. If you had your head gaskets replaced and the shop that did the repairs used six star gaskets, you can use normal green coolant and you DO NOT have to stop the leak, I mean the conditioner in the cooling system.
Starting in 2008, Subaru switched to the new Super long life coolant, which was only supposed to be in the STI for 2008 and all other models until 2009, but we have seen many 2008 Subaru Outbacks come from the factory with blue Super long life coolant liquid. rather than green longevity. If what’s in your car is green it needs to be changed every 30,000 and if it’s blue every 60,000, if you want to try to change at 100,000 you’re doing it at a real risk of repairs down the road.
We’ve heard reports that some dealers have stopped carrying Green long life, but at the time of writing it was still available from Subaru. But knowing Subaru I wouldn’t be surprised if it isn’t available soon.
What A Good Motorcycle Coolant Should Do
The blue coolant is supposed to be changed every 100,000, I think it’s a very bad idea and I suggest every 60,000. If you replace the coolant in an older Subaru model with the new blue coolant, I think it’s not wise to believe that the service interval can stretch to 100,000, and I don’t think it’s worth doing. Interestingly enough Subaru still seems to want the conditioner in, I find it odd that it isn’t in the coolant itself at this stage.
You should not use a long life coolant like Dex Cool. I am not suggesting any form of post leak stoppage.

Internal combustion engines generate a lot of heat, and the coolant, a mixture of antifreeze and water, plays a vital role in regulating their operating temperatures. In winter, the chemical formulas in antifreeze also prevent water and moisture from freezing, which can damage the cooling ducts inside the engine and other components, as well as the pipes in your home. Antifreeze also protects against rust and corrosion, helping to extend the life of water pumps, radiators and other cooling system components.

Performing routine maintenance on your vehicle’s cooling system will ultimately extend the life of your engine. The longer you use the coolant, the more its useful chemical properties break down. Running a car on an older antifreeze or coolant can cause acid build-up, scale formation and reduced resistance to extreme temperatures.
It’s easy to get confused when browsing through the different types of liquids. We have selected five of the best rated antifreeze and coolants that are also compatible with most vehicle makes and models. However, if you’re not sure what fluid to use to keep your vehicle running at its best, consult your owner’s manual or contact a trusted mechanic.
Valvoline’s Maxlife is claimed to be compatible with a wide range of vehicle brands and is also compatible with other coolants on the market, which is useful if you need to top up your coolant in an emergency. It is one of the best fluids when it comes to protecting and lubricating the seals and gaskets in your cooling system, which in turn can prevent coolant leaks. Valvoline claims Maxlife can last up to five years or 150,000 miles. It is more expensive per gallon than other coolants, but the formula is concentrated, designed to be mixed with distilled water. The ideal 50/50 ratio of antifreeze to water helps offset costs.
It is important to protect diesel engines from thermal erosion or pitting of the cylinder walls, and each coolant manufacturer has its own compounds to minimize this type of damage. Shell Rotella ELC nitrite-free coolant concentrate offers superior heat transfer capabilities and aluminum protection compared to conventional coolants without the use of additional additives that can reduce fluid life.
Why Is Coolant Different Colours?
Unlike other competitors, Shell Rotella coolants boast a mileage of up to 600,000 kilometers on the highway or 12,000 hours in commercial machinery. This fluid is suitable for a variety of applications, including new emission engines, especially those with exhaust gas recirculation.
Evans Waterless Heavy Duty Coolant maintains a boiling point of 375 degrees Fahrenheit and contains no silicates or phosphates. Its specially formulated inhibitor package is suitable for all modern and classic petrol, light diesel, propane and CNG engines and requires no additional coolant additives. This formula is even NHRA track approved.
Because this liquid is anhydrous, it eliminates the risk of evaporation, which means that there is no overheating, boiling and subsequent boiling. It also significantly reduces corrosion and electrolysis compared to water-based antifreeze. However, since water should not be added to this coolant, initial costs can add up quickly.
For drivers who don’t want the hassle of mixing coolant with water, Havoline’s Xtended Life formula comes pre-mixed with water. It is ready to use without any additional mixing or steps and can be used in any vehicle that uses ethylene refrigerant. It does not contain silicate, so it is also a good choice for vehicles driven in extremely cold winters. Since it is an ethylene-based coolant, it should not be mixed with propylene coolants, which are often found in older vehicles. Havoline recommends changing the coolant after 150,000 miles.

ACDelco Dex-Cool 50/50 Pre-Mixed Formula is a premium carboxylate technology based phosphate and silicate free coolant formulated to support and optimize the performance of hybrid vehicles. It provides aluminum with excellent high temperature protection and reduces damage to all metal components it comes into contact with, including brass, cast iron, steel, solder and copper.
As with all coolants and antifreezes, maintenance needs can vary, but ACDelco’s Dex-Cool can last up to 5 years or 150,000 miles and has a long 8-year lifespan. However, it must be replaced every 2 years or 30,000 miles in vehicles not originally designed to use Dex-Cool.
We’ve specially selected top-rated, readily available coolants and antifreezes that are compatible with a wide variety of makes and models of vehicles on the road today. We considered the products most affordable to consumers residing across the U.S. and selected five antifreezes and coolants based on a wide range of end-user and expert reviews. Each product is rated based on quality, durability, vehicle compatibility and ability to prevent rust and corrosion.
Antifreeze is highly concentrated and works best as a diluted liquid. A mixture of water and antifreeze, the usual ratio being 50:50, is called coolant. You can buy premixed engine coolant, a ready-to-use mixture of antifreeze and water, or concentrated antifreeze.

The chemical makeup of a refrigerant is more complicated than its color. Older coolants with inorganic additive technology were blue or green and usually had to be changed every two years or every 60,000 miles. Organic Acid Technology (OAT) or hybrid coolants are usually orange and offer better protection with extended coolant life of up to 150,000 miles. Newer coolants based solely on OAT chemistry boast a 300,000 mile drain interval and can appear on store shelves in a variety of colors.
