Procedure

Check with engine cold or at least 30 min after stopping. New means run for less than 5 min. Use the factory belt-tension gauge between any two pulleys; tension is an alternative to deflection inspection. The actual 2005 engine technical-data table explicitly includes BP and BP WITH TC; the displayed setting applies to both.
