Low Conductive Coolant

Low Conductive Coolant | Everything You Need to Know

In summer and winter, a car owner cannot even think of driving his dear possession without checking out the coolant. It must be fine and operating. Why? Well, he doesn’t want to end up with a broken engine in the middle of a busy road. Alright, but why is a low conductive coolant necessary?

I wish I could answer this question briefly. However, its importance pushes me to elaborate on this topic a bit. So, I want to borrow a few moments. I promise, your precious time is going to be invested in something worthy.

What’s So Important About the Conductivity of Coolants?

When your car engine is about to freeze out of the extreme cold, the coolant takes charge of the critical situation and protects the components from corrosives.

On the other hand, when the engine sounds weird due to dangerous heat, it calms it down by maintaining heat balance. It removes the extra heat so that the engine remains safe. So, a coolant with low conductivity plays a double role while ensuring that the engine isn’t affected by high electricity.

Direct and Indirect Contacts: How the Coolants Deal with Them?

With a diesel engine, the coolant will take away one-third of the extra heat.

Now, we might have direct contact between the electronics and the coolant. That’s why the lesser the conductivity, the safer the operation would be. And even if there’s no direct contact between the two mentioned components, there’s always the risk of spills of coolant substance onto the car’s electronics.

Now, what will determine the conductivity of the fluid? It’s the ionic concentration. Yes, with the higher salinity of the substance, you feel less safe about the condition of the engine.

Now, the coolant must not remove too much of the produced heat. For, you don’t want all the energy drained off of your car, right? Likewise, if it removes an insufficient amount of heat, there’s a risk of overheating. And again, a low conductive coolant will be the savior in such a delicate situation.

Water and Glycol: The Combination

Glycol works brilliantly to eliminate the risk of freezing, whereas water will be in the charge of heat transfer.  Therefore, the concentration of water and glycol needs to be spot on. And we mean 50-percent water and 50-percent ethylene glycol. And this is the concentration you will find in most coolants with low conductivity. 

Water and Glycol

Now, if you have trouble with a high ionic concentration in your coolant, what would be the best course of action? Well, I like the idea of using ion exchange resin. It will remove the excessive ionic concentration effectively.

How One Coolant Outruns Another in the Competition?

The core difference among various coolants lies in the additional ingredients they come with. We see the use of antifoams, anti-corrosives, dyes, etc., in many coolants.

They might not seem too useful at first, but when you look deeper into the mechanisms, these are the substances that turn an ordinary fluid into an engine savior.

For example, the silicate-phosphate mix is commonly used in coolants in the west. When you find out about the insulation of metals the mix provides, you will get the wisdom behind the use of these elements.

So, if you use one of those green coolants, make sure that you change it every couple of years, or else it loses effectiveness.

Corrosion: a Problem

If your low conductive coolant isn’t working well, check out if there’s any scale build-up. A substance like magnesium phosphate can mess the whole operation up on a hot engine surface. That’s why I love European products, as they have the solution to this problem, thanks to the silicates and carboxylates they contain.

However, if you are in Asia, you will find the use of phosphates instead of silicates as organic inhibitors. Because, silicates somehow have shown low heat transfer over there.

How to Check the Conductivity?

Using a digital multimeter can be an easy way to make sure that the conductivity is right. If the coolant tester shows that the conductivity is high, you might want to flush and fill the coolant.

Last Words

Before wrapping this up, I am advising you to use a low conductive coolant with proper water-glycol concentration and anti-corrosive properties. And if there’s any query, we will try to be attentive to that.
