Can I Use Vacuum Hose for Coolant Smoothly – Expert Guides 2022

Many people ask- Can I Use Vacuum Hose for Coolant Smoothly? The answer is “No”. You cannot use a vacuum hose for coolant. Coolant is a type of fluid that helps to keep your car engine cool and running smoothly. Radiator fluid is primarily comprised of water and antifreeze, and it moves through the radiator system of your vehicle.

If you need to clear up a clog in your vacuum line, William Alles (who majored in industrial arts education and technology) suggests using the vacuum’s exhaust outlet (quora.com). But advises doing it outside. He also said, “My 40-year-old Hoover can float on the exhaust air coming out of its bottom port, and the port is also set up to receive the twist-on connection of the vacuum’s hose.” You’ll need to use a long wire if this does not work. But be careful not to pierce the hose.


However, vacuum hoses are made of rubber or plastic and are not designed to hold liquids.

I am presenting here-Is it is possible to utilize the hose for the vacuum instead of the coolant. I am also covering silicone vacuum hoses for coolant, types of hoses, using heater hoses for vacuum, fuel hoses using a coolant, and related things. Please stay tuned until finish my post.

So, Let’s get started!

Can I Use Vacuum Hose for Coolant – General Guides

If you use one in place of a proper coolant hose, it is likely to collapse or leak. If your car’s engine becomes too hot, it might seize up.

  • In order to use vacuum filtration, you must first attach one end of the vacuum line to the radiator’s bleeder valves.
  • To create a vacuum, activate the pump by opening the bleeder valves.
  • The vacuum will pull coolant from the radiator into the hose and create a vacuous environment in the cooling system
  • Close off the bleeder valve when coolant starts coming out of it without any air bubbles
  • Remove the hose from both ends and store it appropriately for future use

Can You Use Silicone Vacuum Hose for Coolant?

Can You Use Silicone Vacuum Hose for Coolant?

No, you can’t use a silicone vacuum hose for coolant. Incompatibility between the two materials will lead to overheating and other cooling system issues in your automobile. The silicone vacuum hose is not designed to withstand high temperatures. It also pressures a car’s cooling system and will break down over time.


In order to control or lower the temperature of a system, a coolant (usually a liquid or gas) is introduced into the system. In addition to neither causing nor encouraging rusting in the cooling, an ideal coolant has a high thermal capacity, low viscosity, is inexpensive, and is non-toxic. It is also chemically inert. The ability of the coolant to act as an electrical insulator is essential for several uses.
Your car’s air conditioning system may develop leakage and other issues as a result of this. If you need to replace a coolant hose, make sure to get one that is made specifically for coolant use.

What Type of Hose Can Be Used for Coolant?

You should find the leak in your vehicle’s cooling system and afterward repair it. In some cases, you may also need to replace the hoses that carry coolant to and from the engine. When choosing a replacement hose, it’s important to select one that can handle the temperature and pressure of your car’s coolant system.

The most common type of hose used for coolant applications is a silicone radiator hose. Silicone hoses are able to withstand high temperatures and pressures, making them ideal for use in a car’s cooling system. They’re also relatively inexpensive and easy to find at most auto parts stores.

If your car is equipped with an aftermarket performance radiator, you may need to use a different type of hose. These radiators often require the use of braided stainless steel hoses. These are more expensive than silicone hoses but can handle even higher temperatures and pressures. No matter what type of hose you choose, be sure to get one that is rated for use in an automotive cooling system.

Hoses designed for other applications (such as water or air) may not be able to withstand the temperatures and pressures found in a car’s engine bay.

Can You Use Heater Hose for Vacuum?

Can You Use Heater Hose for Vacuum?

If you need to replace a vacuum hose, can you just use any old garden hose or heater hose? The answer is no. 

Using the incorrect kind of hose may lead to a variety of issues for a number of different reasons.

First, the many kinds of hoses are each constructed from a distinct set of materials. Garden hoses are usually made from PVC. It is not as strong as the material used for vacuum hoses. Because of this, the hose may be more prone to tearing or breaking as a result.

Second, different types of hoses have different diameters. A vacuum hose needs to be narrower than a garden hose so that it can create the suction needed to work properly. If you use a garden hose, the suction will be weaker and won’t work as well.

Finally, several kinds of hoses come in a variety of configurations. Vacuum hoses are typically round while garden hoses are usually flat. This difference in shape means that a garden hose won’t fit snugly into the vacuum cleaner as a proper vacuum hose would.

This could lead to air leaks and reduced performance. So, if you need to replace your vacuum cleaner’s hose, make sure you get the right type of replacement!

Can Fuel Hose Be Used for Coolant?

No, a fuel hose cannot be used for coolant. Your vehicle’s engine needs coolant, a special kind of liquid that keeps maintaining the engine cool and protects it from overheating. Fuel is a flammable liquid that powers your engine.

If you were to use a fuel hose for coolant, it could leak and cause a fire.

Can You Use Hydraulic Hose for Coolant?

Can You Use Hydraulic Hose for Coolant?

It is not recommended to use the hydraulic hose for coolant applications. While a hydraulic hose is designed to withstand high pressure, it is not designed to resist the corrosive properties of coolant fluids. Over time, the hose will degrade, leading to potential failure and leakages.

In addition, coolant fluids can cause the hydraulic hose to swell and become less flexible, making it more susceptible to bursting under pressure.

Final Say

Now you are clear about- Can I Use Vacuum Hose for Coolant Smoothly? If you are looking for a way to cool down your car engine, you may be wondering if you can use a vacuum hose for coolant. The answer is yes, you can! 

Before you go ahead and use this strategy, there are some points that you need to keep in mind. First, check that the hose is constructed of a material that is both long-lasting and capable of withstanding extreme temps. Second, ensure that the hose is long enough to reach from the radiator to the engine block. Finally, remember to bleed the cooling system before starting the engine.

By following these simple steps, you can safely use a vacuum hose for coolant and keep your car running smoothly.
