How to Clean Aluminum Intake Manifold?
Rate this post

Your car’s engine is a finely tuned machine that needs clean air to run properly. The aluminum intake manifold is one of the key components responsible for funneling fresh air into the engine. Over time, this part can become dirty and clogged with oil and debris, causing your car to run poorly. [8] In this article, we will show you how to clean an aluminum intake manifold using safe and effective methods. We’ll also recommend some of the best products on the market for this job. Let’s get started!

Types Of Aluminum Manifold

There are two types of aluminum intake manifold: cast and extruded.

A cast manifold is made by pouring molten aluminum into a mold, while an extruded manifold is made by forcing aluminum through a die.

Extruded manifolds are typically found on performance vehicles because they offer better airflow than cast manifolds.

Types Of Aluminum Manifold

If you have a cast aluminum intake manifold, it’s important to be careful when cleaning it.

Cast aluminum is more prone to warping and damage than extruded aluminum, so you’ll need to take extra care not to damage the manifold while cleaning it.

Here are some tips for cleaning a cast aluminum intake manifold:

  • Use a soft-bristled brush to avoid scratching the surface of the manifold.
  • Be careful not to use too much pressure when scrubbing, as this could damage the manifold.
  • Rinse the manifold thoroughly with water after scrubbing to remove any residual cleaner or debris.
  • Dry the manifold completely before reinstalling it on your vehicle.
If you have an extruded aluminum intake manifold, you can clean it using the same methods as you would use to clean a cast aluminum manifold.

However, because extruded aluminum is stronger and more durable than cast aluminum, you don’t need to be as careful when cleaning it.

Here are some tips for cleaning an extruded aluminum intake manifold:

  • Use a soft-bristled brush to avoid scratching the surface of the manifold.
  • Rinse the manifold thoroughly with water after scrubbing to remove any residual cleaner or debris.
  • Dry the manifold completely before reinstalling it on your vehicle.

If you’re not sure which type of manifold you have, consult your vehicle’s owner’s manual or ask a mechanic. Regardless of the type, both can be cleaned with the same methods.[3]

Why is it Important to Clean an Aluminum Intake Manifold?

As we mentioned before, the purpose of the intake manifold is to evenly distribute the air/fuel mixture to each cylinder head. If there are any restrictions in airflow, it can cause problems with the engine.

Dirty intake manifolds can cause a number of issues, such as:

  • Reduced fuel economy
  • Increased emissions
  • Loss of power
  • Rough idling
  • Stalling

Why is it Important to Clean an Aluminum Intake Manifold?

It’s important to clean the aluminum intake manifold on a regular basis so that these problems don’t occur. In this guide, we will show you how to clean both types of aluminum intake manifolds.

Systematic Procedure of How to Clean Intake Manifold

There are a few different ways that you can clean an aluminum intake manifold. We will go over two of the most popular methods: chemical cleaning and mechanical cleaning.

Chemical Cleaning:

  • Remove the intake manifold from the engine
  • Place the intake manifold in a large container
  • Fill the container with a degreaser or solvent
  • Let the intake manifold soak for a few hours
  • Rinse the intake manifold with water
  • Allow the intake manifold to dry completely
  • Reinstall the intake manifold

Mechanical Cleaning:

  • Remove the intake manifold from the engine
  • Inspect the interior of the intakes for carbon buildup and deposits
  • Use a stiff brush to remove any loose carbon deposits
  • Use a carburetor cleaner or other solvent to remove stubborn carbon buildup
  • Rinse the intake manifold with water
  • Allow the intake manifold to dry completely
  • Reinstall the intake manifold

Ways To Clean An Old Intake Manifold

Cleaning an old intake manifold can be tricky. If the manifold is extremely dirty, you may need to use a strong chemical degreaser. However, if the manifold is only slightly dirty, you can probably get away with using a less aggressive cleaner. Here are some common cleaners that can be used to clean an old intake manifold:

  • Simple Green All-Purpose Cleaner
  • Formula 409 Multi-Surface Cleaner
  • Clorox Disinfecting Wipes

Once you’ve selected a cleaner, you’ll need to decide on the best method for applying it to the manifold. One option is to use a brush or scrubber to work the cleaner into the surface of the manifold. Another option is to soak the manifold in a cleaner solution and then rinse it off with water.[1]

Once you’ve cleaned the manifold, it’s important to dry it off completely.
Otherwise, moisture can cause corrosion and other problems down the road. The best way to dry the manifold is with compressed air or a hair dryer set on low heat.

Finally, you’ll need to apply a protectant to the manifold to help prevent future corrosion. There are a number of different products on the market that can be used for this purpose. Some popular options include WD-40 Specialist Protective White Lithium Grease and CRC Heavy Duty Corrosion Inhibitor Spray.

Ways To Clean An Old Intake Manifold

With a little bit of time and effort, you can easily clean an old intake manifold. Just be sure to choose the right cleaner and follow the manufacturer’s instructions carefully. And don’t forget to apply a protectant after you’re finished cleaning!
