How to Stop Aluminum Rust on an Engine

Engine rust can damage the inner workings of your car's engine.

Metals can get rusted due to corrosion. There are two types of localized corrosion: crevice corrosion and pitting corrosion. Crevice corrosion occurs in the crevices between two components. Pitting corrosion is also called worm-hole corrosion. Pitting penetrates deep into the metal and can cause leaks and compression loss. Pitting can occur due to the presence of halide ions. Aluminum alloys are susceptible to pitting. Use simple measures to prevent rusting due to the accumulation of moisture on your engine's surface.

Instructions

1. Remove any deposits in engine crevices by cleaning vigorously between any small gaps between components.

2. Vacuum out dust and leaves from the engine with a vacuum cleaner hose.

3. Rub a layer of grease across the engine surface in order to prevent moisture from accumulating on the engine's surface.

4. Park your car inside in rainy and snowy weather.
