Are You Getting Water in Your Air Intake System? | Donaldson Engine & Vehicle (2024)

FAQs

What happens if water gets in your air intake? ›

Unfortunately, this moisture can have some undesirable effects, including: Giving higher restriction readings. Causing any residual dust to cake into mud. Causing blocked vacuator valves.

When operating equipment in wet weather conditions, it is common for excess moisture to be drawn into the air intake system. This is particularly common in on-highway equipment which often operates at high speed in very wet weather.

If your car's engine has been submerged in water, there's a good chance it's suffered serious damage. Water can cause all sorts of problems when it comes into contact with electrical components and moving parts, and it's likely that many of the intricate systems inside your engine have been damaged beyond repair.

Insufficient sealing of the engine compartment allows water to make contact with some powertrain components and the air filter.

One key to water elimination is to cool the air passing through the aftercooler to less than room temperature or as low as possible. Air which has once been cooled to less than room temperature will usually not drop any more water after it has warmed back up to room temperature.

A powerful shop-vac run over the plug holes can evacuate water as well, without leaving any paper towel residue. Another technique is to disconnect the fuel injectors and crank the engine over. The starter should have enough torque to fling all the standing water out of the spark plug holes in just a few revolutions.

If water gets into the air intake system of your car and enters the fuel system, it can alter the air/fuel ratio and lessen engine power. This situation is also known as hydrolock and can cause the engine to stall. If the water in the combustion chamber is in small amounts, it is often eliminated by engine heat.

You get some of the water in your body through the foods you eat. Some of the water is made during the process of metabolism. You also get water through liquid foods and beverages, such as soup, milk, tea, coffee, soda, drinking water, and juices. Alcohol does not add to the body's water because it is a diuretic.

Yes, it is possible to repair an engine that suffers from a hydrostatic lock. However, the process can be costly and time-consuming. That will depend on the extent of the damage. For instance, if the damage is minor, you can restore the engine with a new set of spark plugs and a change of fluids and oils.

Generally, even a small amount of water can have detrimental effects on your car's engine. For example, as little as half an ounce of water in a 15-gallon gas tank can cause issues with engine performance and fuel efficiency, leading to potential car repairs.

Floodwater Can Cause Mechanical Damage

When floodwater makes its way inside a vehicle's engine and/or drivetrain, any fluids inside those assemblies will be ruined and will require replacement. Corrosion or clogging of vital passages and lines will follow quickly.

Primary fuel filters, also known as fuel filter water separators, use a variety of methods to separate water from fuel. Accumulated water can then be drained from the filter drain valve during recommended service intervals.

However, if the air filter gets soaked, that water starts to displace and close off all of the pathways that air takes through the filter and into the engine. This cuts the airflow and causes the engine to run rich.

Depending on your equipment's needs there are many types of oil filters and as they are designed to capture various kinds of contaminants with varying degrees of performance. The primary contaminant targeted by oil filters are solid particles, but there are many oil filters that absorb water.

If there is water buildup in your home's air ducts, it will seriously compromise the home's indoor air quality and overall safety.

Use dehumidifiers and air conditioners, especially in hot, humid climates, to reduce moisture in the air, but be sure that the appliances themselves don't become sources of biological pollutants. Raise the temperature of cold surfaces where moisture condenses. Use insulation or storm windows.

After driving through a deep puddle, it's important to check your car for any damage that may have been caused. Standing water often contains debris or chemicals that can damage your car. If you notice any damage, you should take care the car to an auto service.
