Detailing your engine bay and keeping it clean not only makes working on your engine easier but it shows a sense of pride of ownership. Modern engines are fairly easy to clean and detail, but keep in mind that you will using liquids and water around electrical equipment. Modern cars are sealed very well from the factory, but you should protect equipment such as the ECU or the Alternator. If you don't know what these are or what they look like, then you shouldn't
detail your engine.
A quality degreaser such as Eimann Fabrik's VOC Engine Degreaser or Meguiars Super Degreaser
A couple of brushes (I use old paint brushes)
Your favorite dressing such as Meguiars Natural Shine, Meguiars Hyperdressing or 1Z's Vinyl-Rubber Care and Protectant
The engine can be warm or cool to the touch, although warmer temperatures will help break down grease and grime. However you do NOT
want to spray cool water on a hot engine!
Use aluminum foil and wrap it around sensitive electrical equipment such as alternator or the ECU. Do NOT
use aluminum foil on the battery as you could bridge the terminals.
Where gloves and eye protection to protect against any caustic chemicals. You do NOT
want engine degreaser ending up in your eye's!
Spray a liberal amount of engine degreaser on all areas that need to be cleaned and allow to dwell for 30 seconds.
Agitate the degreaser into a lather using a soft brush to help facilitate the removal of stubborn grease and grit.
Rinse throughly using flowing water. Avoid spraying water with pressure on to sensitive equipment, but rather work around them. Rinse all solution off the engine, fire wall, and inner fenders.
Dry the engine as much as possible. If you have a high speed electric leaf blower use it remove as much standing water as possible from all the various nooks and crannies. If you have a wet vac you can use this to such water out of tight areas. If you have neither use a towel to soak up as much as possible.
Close engine bay and start engine. Allow to run up to normal operating temperature for at least 5 minutes.
After engine dries, apply your favorite dressing to the hoses and plastics, and enjoy
This Hyundai was in desperate need of having its engine detailed. A perfect demo car in need of some love!
I sprayed the engine compartment down with a liberal coat of Eimann Fabrik's VOC Engine Degreaser. The degreaser immediately began to loosen the grease and grime.
Very dirty areas require agitation with a soft brush.
The underside of the hood was very dirty as well, and in need of a little cleaning.
After flushing the engine bay throughly with water, little areas of grime might remain. This is a perfect time, if you desire, to get out a q-tip and clean any spots up.
Remove as much standing water as possible, then close the engine and allow it to run up to operation temperature to facilitate drying. After it cools down, apply your favorite dressing and enjoy! I used 1Z Rubber-Vinyl Care 'Tienfienpfleger.
