2002-2003 Acura 3.2L SOHC Engines Revised Timing Belt Tensioner

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 tension and allow the loss of cam timing. Vehicles with the revised tensioner should be identified by a punched mark above the sixth digit of the engine compartment VIN code as shown: 19UUA5XXXXXXXXXXX
