A revised timing belt tensioner for 2002-2003 Acura 3.2L engines is part of a product improvement by Acura. The original design timing belt tensioner is filled with oil to dampen oscillation. Due to a manufacturing situation, the tensioner oil can leak. If enough oil is lost, the timing belt loosens and causes engine noise. The worst-case scenario is the belt may lose Read the rest of this entry »

The Pathfinder was first launched in 1987 as a derivative of Nissan’s pickup truck line. Available initially as a two-door, it was joined by a four-door version in 1990, which has been the sole body style since 1991. The original Pathfinder changed very little on the outside during its life, but was treated to a new dash and interior design in 1994. Whereas the first-generation Pathfinder was a body-on-frame design, the all-new 1996 Pathfinder featured unibody construction. In mid-1999, the Pathfinder, designated as a 1999.5 model, was face-lifted and moved upmarket. Nissan slotted its new Frontier pickup-based body-on-frame Xterra into the space in the lineup vacated by the old base model Pathfinder.
