SOURCE: How hard is it to change alternator and thermostat

Those are both hardy parts that should last close to 100,000 miles, but if you need to replace them it's not real difficult, especially since there's plenty of room under the hood. The alternator is a matter of 3 or 4 bolts. Remove the plug-in wire harness from the alternator, loosen the adjuster bolt to take tension off the belt, then remove the mounting bolts and pull the alternator. Reverse the steps for the install. For the thermostat, follow the upper radiator hose to the point where it enters the engine. The hose is connected to a metal housing that's bolted to the engine. Unbolt the housing from the engine to expose the thermostat. Lift the thermostat out, remove all traces of gasket from the housing and engine, then install the new thermostat and gasket.

Timing chains don't have a regular service interval like a timing belt does. It should last the life of the vehicle.

The trick is to remove the cap on the brake fluid reservoir on the firewall under the hood before squeezing the caliper. Be sure to replace the cap before attempting to press the brake pedal.
