My 2006 honda civic dx is missing the plastic part that is under the engine that protects it

The front engine cover located on the underside of the front of engine can be replaced as a used part.check your local used parts places.it doe not have to be new as it only protects the engine from water,ice,snow. from going into or onto your engine,but without it,you may have a water problem that this cover prevents. suggest you call used part suppliers in your area ffor a replacement. the replacement is easy,if you are mechanically inclined,if not suggest you ask parts place to recommend at least 2 places and get an estimate of replacement of the part,if you supply the part.hope this helps and thank you for choosing fixya.com
