Awesome video. Thanks for that and all the comments that followed. I have a 2009 Rogue with 53k miles but it has been back at Nissan at Nissan many times these past 2 years for recalls and warranty work and every time since it hit 40k they have been telling me to pay them $140 to change the belt because it was in very bad shape so I decided to follow the video and service manual and do it myself.
I did not have the OEM but the Goodyear Gatorback 6PK1805 (I think is costs $7.19 on Amazon) and I can confirm that it is a few mm shorter (1805mm for the 6PK1805 vs 1808mm for the 11720-JG30B) but still installs within specs
Had some trouble installing because I was trying to get it around the crankshaft and tensioner as the last step. But as the manual says (step 3 of installation),
do the water pump last. Doing so, I was able to get it in place but having no help around, had to use 2 extensions and a breaker bar that I basically sat on while holding the top end with one hand and slipped the belt over the water pump using the circular part of the jack handle. Should have had a helper or just gotten the OEM belt.
Thanks for all the information on this forum
