All of the 2.5-liter 4-cylinder engines for this generation have a timing belt made of rubber and cord. A belt must be replaced at . These engines are interference engines, meaning that if the timing belt breaks or stretches, the pistons will hit the valves, requiring an engine teardown, and a likely rebuild. Also, if this belt is replaced around 105,000 miles, it is a good idea to change the water pump, thermostat, belt tensioner and all the idler pulleys for this belt. The water pump and thermostat are behind this belt.
