Yeah Its about time, Im sure you could go 90k on it though. Back in '91 they reccomended it to be changed every 60k. Check the waterpump for leaks and cam/cranks seals for any leaks while in there. Now would also be a good time to change the waterpump as preventative maintenance. As well as the serpentine belts if they are old, they are coming off anyways.:thumbup:
