AS WITH ALL MY VIDEOS I TRY TO GIVE THE MOST INFORMATION IN THE LEAST AMOUNT OF TIME AS POSSIBLE SO I DON'T WASTE YOUR TIME. IN THIS VIDEO I AM CHANGING ALL THREE OF THE ENGINE DRIVE BELTS ON MY 2004 NISSAN EXTERRA WITH THE 3.3L GAS ENGINE HOWEVER THE PROCESS SHOULD BE THE SAME FOR ANY NISSAN EXTERRA OR FRONTIER WITH THE 3.3L BETWEEN THE YEARS OR 1999-2004. THE REASON FOR CHANGING THESE BELTS IS I WAS DOING A TIMING BELT ON THE VEHICLE AND HAD TO TAKE THEM OFF FOR THAT ANYWAY. BECAUSE OF THAT IT IS VERY EASY TO SEE HOW THE BELTS GO ON SINCE I HAD THE RADIATOR OUT OF THE VEHICLE BUT I DO HAVE CLIPS OF CHANGING THE BELTS WITH THE RADIATOR IN THE VEHICLE AS WELL WHILE I WAS TRYING ATO DIAGNOSE WHICH ONE OF THE BELTS WAS SQUEALING. I ALSO GO OVER REASONS YOUR BELT MIGHT HAVE GONE OUT OR WEAR OUT PREMATURELY AND WAYS TO CORRECT IT.
