just bought w/ 140k miles, rides rough (big old tires) & boiling sounds in motor

What is your question?

it's has beefy austrailian suspension and aggresive tires that look worn...i rode it around the city for a few hours and when i turned it off, there was a boiling sound coming from the motor...just purchased it w/140k miles, what should i do for service to be safe and what about the rough noisy ride (tire change? or suspension/cv boots/etc check) and boiling sound from engine! i hope its not a lemon, it's so cool. thank you for any advice.
