as long as it is running fine no you don't. i understand your concerns but preventive maint on this is very exp.when they go out its like all of a sudden with no warning also ficm are also known for failure.the only thing i would do is repl water pump and belt at this time.most oil pumps and ficm last till approx 100k miles
