How to Remove the Upper Timing Belt Cover on a 1994 Honda Accord

The upper timing belt cover on the 1994 Honda Accord is used to protect the timing belt and other engine components from dirt and debris. If foreign material enters this area, early wear could result. This cover is also used to hold the wiring harness for the alternator in place.

Disconnect the negative battery cable. Position the cable so that it cannot contact the battery terminal.

Carefully insert a screwdriver between the valve cover and head. Gently pry the valve cover off of the head and set aside.
