Normally the tune ups for cars are scheduled at 30K, 60K and 90K. If you do not have the maintenance records of this car then, you have to change the fluids, and inspect many things.
You have to flush radiator, flush braking system, change engine oil, and the transmission oil.
Inspect and replace if necessary, the spark plugs, spark plug wires, serpentine belt and belt tensioner.
The ball joints and tie rod ends has to be inspected too.
The most important thing is to make sure that the timing chain has been replaced. It listed for $142 at NAPA parts.

You gotta move the idler pully with a wrench and the belt will loosen enough to come off. The trick is that you have to have one hand on the wrench holding the pully down while you r & r the belt. My wife held it for me when I did mine
