1995-2002 Toyota 4Runner 3.4L Timing Belt/ Water Pump Replacement

As a rule of thumb, it is best practice to replace the timing belt and water pump together every 60k miles.

Part 1 is only needed if you are looking to replace only the water pump.

Since the timing cover is off and there is easy access, consider replacing both idlers, tensioner, accessory belts, thermostat and hose.
