I may be preaching to the choir here, but if you're doing the timing belt make sure you've got a new water pump, belt tensioner, belts, hoses, coolant, thermostat, spark plugs, etc. , etc. so you can slay all your underhood maintenance issues at one time. I'm not sure if the crankshaft bolt issue applies to Monteros as late as yours but that would be something else to check on while you're in there.
