2002 Subaru Legacy GT – timing belt replacement

Dear Doctor: I have a 2002 Subaru Legacy GT four-cylinder with 170,000 miles. The original timing belt was replaced at 105,000 miles (100,000 mile manufacturer recommendation). The shop advises that I replace the timing belt again between 165,000 and 170,000 miles. Why isn’t the second belt recommended to be changed at 200,000 miles? Keith


Dear Keith: The best way to answer your question is to advise you that when it comes to engine timing belts I always tell my customers to follow the carmaker’s recommendations on timing belt replacement. I also insist on the use of the factory brand timing belt. The factory timing belts have marks on them to aid in lining up the pulleys.
