Your 3.0 Liter V6 is called an %26quot;interference%26quot; engine that may be severely damaged if the timing belt breaks. Therefore, you must change the belt every 60,000 miles as your Nissan owner%26#039;s manual instructs or you risk $$$ damage to the engine. Your water pump does not appear to be driven by the timing belt so you don%26#039;t have to change the water pump, but you should replace the timing belt tensioner and idler pulleys for sure if they%26#039;ve never been replaced. Total cost at a Nissan dealer is about $850.|||is it a belt or chain
belts every other year unless you put alot of miles on a year. chains further i would change chains every 4-5 years.|||Timing CHAIN?
The chain should not be replaced unless there is a problem with it. A BELT should be replaced when the mfr tells you, usually around 60,000-100,000 miles.
