Steps Of How To Clean And Polish An Aluminum Intake Manifold Without Removing It
Cleaning and polishing an aluminum intake manifold, both the inside and outside, can be done without professional assistance.
In this regard, the following are the simple steps to clean and polish an aluminum intake manifold.
You can use these steps to clean and polish the aluminum intake manifold without removing it from the car.
Maybe you could be asking yourself if these steps you can use on your modern engine car.
If you have a car with a modern engine, worry less because these steps you can use to clean and remove carbon buildup inside aluminum intake manifolds of modern engines.
Identify And Park The Car In A Well-Ventilated Space
Before cleaning and polishing the aluminum intake manifold, park the car in a well-ventilated and shady area. It is to prevent suffocation caused by harmful exhaust fumes.
Ensure that there are no children close to where you will be cleaning the aluminum intake manifold.
Additionally, make sure there are no other chemicals. It prevents any unwanted accidents caused by chemical reactions with harmful exhaust fumes.
Switch Off The Car Engine And Disconnect The Throttle And Air Intake Tube
After placing the car in a well-ventilated area, you need to turn off the engine if it is still on. The next thing you need to do is to disconnect the throttle.
Disconnecting means separating the throttle from the air intake valve and not removing it from the car’s engine. Again, remember to keep the engine turned off during this process.
Next, go through the air intake duct and disconnect it from the throttle body to ensure that it is ready to work with the car engine.
Clean The Throttle Valve Using The Foam Cleaner
After disconnecting the air intake duct, you can clean the aluminum intake manifold by spraying the throttle valve.
Clean the inside and outside of the aluminum intake manifold by spraying the power foam on the throttle valve.
Be careful during this step because you use a chemical to clean the aluminum intake manifold. This process requires a lot of foam cleaner sprays.
Try to spray at least half of the power foam cleaner can for just this purpose. Use it to clean and polish the inside and outside of the aluminum intake manifold.
Using the clean microfiber or cotton cloth, clean the excess liquid off the valve’s plate. Lastly, connect the air intake tube back to the throttle valve.
Clean And Wipe The Dirt From The Aluminum Intake Manifold
Like the throttle valve, the vacuum hose is first detached from the aluminum intake manifold. It is an essential step because spraying the power foam cleaner into the vacuum line.
To allow the sprayed power foam cleaner to settle, give it 5 minutes. Taking a break and leaving the spray there gives it ample time to soak in.
