Corrosion or rusting may slowly damage all the parts of your vehicles. Therefore, proper maintenance and regular servicing are essential to deal with such issues. When the corrosion is related to the engine then the complications and severity are much increased rather than in other cases. So, in this article, we will discuss in detail the corrosion related to the engine. We’ll deal with the ways about how to clean aluminum engine corrosion, its causes, and certain frequently asked questions related to the topic.
What Are The Causes Of Engine Corrosion In The Vehicle?
There are multiple reasons responsible for the corrosion of the engine’s components. However, the most commonly or frequently accepted theory for the cause of corrosion is the action of sulphuric acid, which is formed by the combination of sulfur in the fuel and lubricating oil with water entering or produced in the engine itself.
How To Clean Aluminum Engine Corrosion?
As the corrosion in car parts is pretty common whether it’s a small part or a most crucial part like an engine. The immediate treatment is essential in such cases as proper engine functionality is the prime most thing.
So, we will discuss certain steps to clean the aluminum engine corrosion. You only need to follow all the procedures sequentially and calmly.
To begin with the procedure, first of all, you need to get the cleaning product necessary for the purpose. Then, remove all the battery cables for safety purposes. Disconnect the negative cable first followed by the positive terminals. The terminals of these cables are highly corrosive, therefore doing their maintenance properly will help you to overcome the issue.
Next, clean the battery tray as corrosion is not limited to the cables. Hence, the battery tray needs periodic cleaning and replacement. Also, be careful while cleaning the battery and do not use flame near them. And wire brushes the corrosion, for this, you may need some baking soda and water paste to neutralize any spilled acid.
Soon after completing all the points mentioned above, move on to the next step. Here, you first need to use rust-resistant enamel for coating the battery tray and touch up other parts also to prevent corrosion. Next, soak the cable end in a clean and clear tin filled with CLR or any corrosion neutralizer.
Now, use the available terminal brush to have squeaky clean. Further, use dielectric grease to help protect the clean terminals from oxidation and in turn corrosion. Dielectric grease is non-conductive and water-resistant.
You can use white grease on silicone seals as they may become soft applying dielectric grease. Also, you can wire brush the hold-down bolt to remove any accumulated rust before reinstallation.
Next, anti-seize the compound to protect it from further corrosion. After following all the above steps then move to the engine area. Here, cover the sensitive electrical parts like the alternator, distributor, or relay boxes with plastic bags to prevent them from getting over-soaked.
Use the compressed air to blow out any loose dust present in the area. You can also use a vacuum cleaner for this purpose. Now, spray the engine cleaner on the greasy engine and stay away from the exposed electrical parts. For those exposed electrical parts, you can use non-residue dry brake cleaner. After spraying leave it for some time for approximately thirty minutes and let it soak.
The safe alternator to engine degreaser is the simple green which is easily available in the nearby shop or on a variety of online sites. However, be careful while using the pressurized sprays as you don’t have to force solvents into the electrical connections, engine orifices, or sensitive components.
Also, you can use mineral spirits and a siphon sprayer to degrease an engine. Next, prepare an engine block to clean using either compressed air or mineral spirits. Also, clean the exposed raw aluminum parts with the help of a small wire brush or CLR and scrub plastic parts, however, you can use brake cleaner to remove grease from tricky areas.
After cleaning the aluminum engine corrosion, check for certain leaks like oil or coolant leaks if present. For checking the leaks, you can use the blue lens on your mini-mag flashlight. Hence, it’s the last step of the procedure, and you are done with all the corrosive parts or areas of the engine.
How Do You Remove Oxidation From Engine Blocks?
There are a variety of products to deal with such issues, but frequently and most commonly used product is aluminum brightener in a spray bottle. It works pretty well for cleaning the oxidation and grime off of bare aluminum parts. Spray the product on the affected part and let it soak a little bit then scrub with a brush and rinse with water.
Can You Clean Your Engine With WD40?
It is regarded as one of the best ways to handle the issues related to engine cleaning. To do this, grab a handy degreaser spray, WD-40 which is a specialized and fast-acting degreaser spray. The fast-acting, solvent-based engine degreaser can effectively remove grease and grime from your engine without leaving residue.
How To Remove White Corrosion From Aluminum?
For removing the white corrosion from the aluminum engine, you need to follow the simple steps. First of all, wet the rusted area with water, and apply a commercial rust remover to the surface for heavy patches of rust. Then, scrub the surface vigorously using a wire brush and rinse the surface completely. At last, blot dry with the towel to have the final result.
