Engine area or the engine bay is often ignored when it comes to cleaning and washing the rest of the car. However, it is important that it is kept cleaned and free from dust and build up to ensure smooth operation and a clean look.
I have done this many many times so i thought i should post a Do It Yourself on it. This was done on a Civic but the stpes can be followed for any car. Here is how you go:
Before You Start:
1) The engine should be cold so wait after u have driven
2) Do it during the day and not in dark so u can see properly
3) The car should be parked in a shade and not in the open.
4) water connection and pipe, engine cleaner and some excitement..lol
Step 1: Getting Ready
1) Once ur ready, open the hood and secure it properly
2) Do a visual inspection to see if there are any naked wires (where u can see the copper)..if u find any..tape them so there is no contact with water
3) Check for anything loose...battery tie down, batter terminals..and anything that can move
4)Get some clean garbage bags (thelis) and cover the following with them so that water does not get in...
a) the top of the battery
b) the distributor cap
c) the alternator
d) opening of the air intake & filter (if u have an open one)
Step:2 - Pre Soak
Set the water pipe or spray to light pressure...we dont want alot of water at this stage. Just lightly wash all of the engine area with equal amounts of water...go slow..there is no rush...make sure all areas are wet. dont use more water on items that u just covered..i.e. battery etc.
Step:3 - Apply Cleaning Solution
I am not sure if you buy a engine degreaser or cleaner in Karachi but if u can...thats great. If u dont have anything specific available...get a rubber foam cleaner (anything that is general purpose). Dont use surf or any household cleaners...they will cause more harm than good
Just spray the cleaner or the foam all over the place...make sure each area is well covered with the solution (plastic, rubber and metal parts). Use even coats to make sure it gets there.
Step:4 - Now Wait
Now just leave the hood open and wait for about 15 minutes. Go have a cigarette or call a friend. You have to give this time so that the degreaser in the solution can penetrate all the dust and grease buildup.
Step:5 - Wash
Now set the water a little high pressure and start washing the whole of engine area. Just make sure all the solution is gone....again...dont apply alot of pressure on areas that you covered. you will notice all the dirt now going away. Do this for no more than 5 minutes cuz too much water is also not good.
Step:5 - Now Inspect the Engine
Inspect after you have rinsed and washed the engine. Look for spots where u still have dirt...you will find little nooks and corners which didnt get clean....use an old tooth brush and an old cloth. Remove the thelis over the battery, alternator and the dcap etc.
Step:6 - Dry and Polish
This step only applies if u wanna go the extra mile. I always do this cuz it brings out the shine.
After u have wahsed and checked everything...wait for around half an hour till all is dry. Take a detailer or a light wax and apply and clean the plastic and metal areas...make sure the areas are dry...then apply polish and clean them...u will see a beautiful shiny engine bay.
Now stand back...enjoy and take some pics. Here are some photos that i took after i did mine a while back. You will notice that my engine was not dirty to start with cuz i clean it once every couple of months....lol. If u have any questions...let me know.
Thanks...Salman
