How To Add Liquid To Coolant Recovery System

How To Add Liquid To Coolant Recovery System

If your car has a coolant recovery system, you can check the level of liquid on the side of the plastic reservoir. You just open the cap on the reservoir to check whether the coolant looks as though it needs changing or to add water and coolant. Many vehicles have a pressurized coolant recovery system called an expansion tank that makes opening the radiator unnecessary. These systems are considered “sealed” because the safety pressure cap is on the recovery reservoir rather than on the radiator.

  • If you overfill the system, the extra liquid gets hot, expands, and flows out of the overflow pipe. That may not seem too terrible, but because coolant is toxic, it can harm animals or children, who love its sweet taste.
  • If you don’t have coolant on hand and you just need to add a little liquid to the cooling system, plain old tap water will do. But try to maintain a good coolant level by adding a similar amount of straight coolant the next time you add liquid to the system.

You will probably never need to open the cap on the radiator, but if you have to open the cap for any reason, make sure to fill the radiator to the top with a 50/50 mixture of coolant and water before replacing the cap. This addition bleeds the system by forcing any air that may have gotten into the system into the reservoir and out through its overflow pipe when the engine heats up. Follow these steps when adding liquid to the coolant recovery system:

Adding cold liquid to an engine that’s hot can crack the engine block because the hot metal contracts sharply when the cold liquid hits it.

  1. Check the liquid level.

    Look at the outside of the reservoir to see where the level of the liquid in it lies relative to the “MAX” and “MIN” lines embossed on the side, as shown here.

  2. Lift the lever on the safety cap to allow the pressure to escape.

    To keep from burning your hand, place a cloth over the cap after you raise the lever. Then turn the cap counterclockwise to remove it.

  3. If the liquid level is low, add equal parts coolant and water to the reservoir.

    Add equal parts coolant and water until the level reaches the “MAX” line on the side of the container.

Synthetic Oil

Synthetic oil vs. Conventional Oil

Conventional and synthetic oils begin in the ground. But that’s where the similarities end. 

Synthetic oil is not only refined but also distilled, purified and broken down into its basic molecules. This process not only removes more impurities from the crude oil but also enables individual molecules in the oil to be tailored to the demands of modern engines. These customized molecules provide higher levels of protection and performance than conventional oils. But the synthetic base oil is only half the story. The correct blend additives must go into the mix to create the oil.

Our Synthetic Oil has a unique, balanced formulation to keep your engine running like new. So what are the benefits of using professionals? We will pick the correct oil for your needs like Synthetics typically outperform conventional motor oils in providing more protection for your vehicle. Here’s how all that chemistry translates to the real world.

Synthetic motor oil keeping your engine clean

Keep your engine cleaner
As oil circulates through your engine it can pick up deposits. Over time, conventional oils can sometimes form sludge, which can reduce your engine’s efficiency and, ultimately, reduce the life of your engine. Synthetic oils contain fewer impurities compared to conventional motor oils and can better resist the formation of sludge thereby preventing deposits from forming in your engine.


Synthetic motor oil for engine wear protection

Offer greater engine wear protection
Engine parts are in constant contact with each other. They’re also moving at high speeds. In the extreme environment of your engine, components can wear and break down. Your motor oil is the protective barrier between these components. As conventional oils break down, their ability to prevent engine wear diminishes. Synthetic motor oils, on the other hand, retain their wear protection properties for a much longer time, increasing engine life.

Flow better in low temperatures
When your car sits for awhile (let’s say overnight) the oil settles. But, when you fire up the ignition, it begins flowing through critical engine parts to protect against friction. With conventional oils, it takes more time until they are able to flow smoothly through the engine. During the cold winter months, or if you live in an extremely cold environment, this flow process takes even longer. Synthetic motor oils, however, are engineered to flow quickly even at low temperatures, and they start protecting your engine right after you start your car.

Protect better at high temperatures
When running, engines are hot. Really, really hot. Over time, the high temperatures in your engine can cause conventional motor oils to break down or evaporate exposing your engine to wear. Synthetic motor oils are engineered to resist these high temperatures, which is especially important if you’re driving in hot climates.


Synthetic oil protects turbocharger engine parts

Protect critical turbocharger parts
To meet consumer demand, automakers are building cars with smaller engines (for greater fuel efficiency) but adding turbochargers (to boost power). We already mentioned how engines run at high temperatures, which can break down conventional oils faster, but today’s turbocharged engines are even more aggressive. The shaft inside a turbocharger can spin upwards of 200,000 revolutions per minute, so it’s critical that your motor oil can get to that shaft and lubricate it properly very quickly. Conventional oils can break down faster under these conditions and leave deposits on turbocharger components, which can lead to failure. Synthetic oil can protect these components much better than conventional oils, keeping them operating at peak performance and boosting your engine’s power.
