excuse my ignorgance. my recently purchased 2001 forester with 85000 miles will be getting a new head gasket this week with subaru footing the bill. my question is this. does the existing timing belt and water pump need to be removed for this replacement of the head gasket? if so, should i have a new timing belt and water pump installed for the price of the parts? sounds like a no brainer to me since the belt should be replaced at 105,000 miles anyway.
