How often does 2008+ G35xs owners change their Serpentine belts?? Thinking about doing mine today I have 50k miles on the car.

 

You can change it whenever you want...50k miles is good...do they make any noises at all..?

 

Actually they don't at all but when I went to get a oil change and tire rotated they ask me to change the air filters and belt when I get the chance. I did two new k&n
Filters and ordered a new belt at the shop. I guess I would be doing some good forecasting

 

Well you can never go wrong with taking precaution haha

 

would a high pitch squeaking after cold start be because i need to change my belt?

 

fyi there is only one belt on the V36 to replace and if you read in the diy section most last quite some time while others have snapped early mainly due to the auto tensioner not acting properly. Best way is to inspect the belt visually for cracks and crumbling.

 

Ya most of the time....or this can mean that the belt is a bit lose...just look at the belt closely (from the inside) to see if there are cracks or signs in wear

 

You can easily replace the belt in ~15 minutes in good weather. just check out my DIY and save yourself some dough!

My Infiniti mechanic told me the new generation serpentine belt in the G is made with EPDM - you can google it - and as a practical matter they could probably be lifetime. As it's a cheap maintenance, you can do it anytime, but the mechanic told me it's virtually certain the belt would last 100k or more. I'm going to do every 60k since it's cheap. I think he also said with the EPDM belt it's not really the visual inspection for cracks that matter, but I can't remember what did.

 

Get outta here that's some good info. Lol
