Continuing on with my series on Discovering AMSOIL, our coolant / antifreeze product line. It just so happened, coincidentally enough, AMSOIL posted on their blog a good article on why a good quality coolant is important and how AMSOIL products can provide that quality. Read the full article here, but let me point out some interesting tidbits.
A large percentage of engine failures can be linked to the cooling system. One of the more important things to take care of is to be sure that your coolant is flowing freely. Over time, sludge can form leading to a plugged radiator or fluid passages. This of course can lead to overheating. Not a good thing. But what is sludge and why does it form? Let’s look at what the AMSOIL article has to say.
Additives dropping out: coolant consists of a base (typically ethylene glycol or propylene glycol) mixed with additives and water. The base is primarily responsible for providing freeze and boil-over protection. The additives guard against corrosion, cavitation and scaling. Mixing of incompatible coolants, however, can cause the additives to “drop out” of the solution and form sludge or slime.
Essentially particles from the additives can drop out of solution and pool together in the coolant system. When this happens, not only does your antifreeze lose performance, but those particles group together to form sludge.
Contaminated Coolant: a bad head gasket or cracked cylinder head can allow oil and coolant to mix, resulting in sludge. In vehicles with automatic transmissions, the engine-cooling system also cools the transmission, and a breach in the system can contaminate coolant with transmission fluid.
Never a good thing if you are getting oil into your coolant system. Yes it can form sludge, but obviously you’ve got other issues that need to be addressed as well. If this is happening, you’ll want to take care of the problem.
Corrosion: occurs when an imbalanced coolant chemically reacts with metallic surfaces, forming reddish deposits that can appear as sludge or slime.
Metal and fluids will often react together in normal operation to form deposits leading to coolant system issues.
What if I have sludge already?
If you are seeing some sludge or residue in your system, you’ll want to find out what is causing it. You’ll want to do a fluid analysis, which will identify if there is oil, transmission fluid or some other contaminant in your coolant. This can guide you to any mechanical repairs that may be needed. Then you can flush your coolant system and refill with a high quality antifreeze.
Aren’t all Coolants the Same?
Short answer, no their aren’t. Most of the inexpensive coolants contain inorganic salts (nitrates, phosphates, and silicates). These deplete quickly and can be an environmental hazard. Those salts, as they deplete will form deposits and sludge.
A higher quality coolant, while costing more, can last longer and and are more durable. The use organic-acid tech (OATs) and will virtually eliminate drop-out and scaling. This is the way you want to move towards. Yes they often cost more, but can often help prevent costly mechanical issues and repairs.
What does AMSOIL provide?
Well of course, I couldn’t leave here without telling you what we have to offer in the way of coolants and antifreeze. Well we offer three different coolants. Check out each of there pages for more detail, but their unique blends are designed to work faster and offer enhanced protection.
We also offer a neat little product called Dominator Coolant Boost. This product helps to reduce operating temperatures and will significantly reduce engine warm-up times in cold weather. This can be used in racing applications using straight water coolant and automative applications using a 50/50 coolant / water mixture. It’s a great little product.
So there ya go, a high-level view of just one of the many product lines that AMSOIL has to offer. If you want to another article that goes into a little more detail on how coolants work and the different types you will run across there is another good article that you can read and enjoy on high-quality antifreeze.
As always, please let me know if you have any questions or want to learn more about AMSOIL, it’s products or business opportunities!
