DanF. Posted February 6, 2016 Share Posted February 6, 2016 2004 R50 Pathfinder SE 3.5L A/T Hey all, I'm searching for the cause of a loud, squealing noise, that lasts from 10-30 seconds on a cold startup. I'm sure it's one of the belts, but I'm looking for a diagram, and can't find which section of the repair manual to search in. Here's the link to the index of the R50 repair manual: http://www.nicoclub.com/FSM/Pathfinder/2004_Pathfinder/idx.pdf Is there a tensioner that I can adjust? A cursory look showed the belts to be in serviceable condition. Link to comment Share on other sites More sharing options...
jyeager Posted February 6, 2016 Share Posted February 6, 2016 Yes, there is a tensioner and it's very easy to adjust. See if this video helps you. It's for a front wheel drive car, but the engine should be the same, just turned sideways. If that doesn't fix it, then the squealing is probably coming from the power steering pump. That's a separate belt you can only get to from the bottom and it adjusts separately, without a separate tensioner because it's the only thing on that belt. 2 Link to comment Share on other sites More sharing options...
Kingman Posted February 7, 2016 Share Posted February 7, 2016 Two tensioners you get to from underneath the truck. 12mm and 14mm I believe. Make sure the belt is just loose and not too thin or cracked before tightening them up. 1 Link to comment Share on other sites More sharing options...
Storm_Trooper Posted February 29, 2016 Share Posted February 29, 2016 Suggest Goodyear Gatorback Belts if you want the best Link to comment Share on other sites More sharing options...

Shoot some belt dressing on it too, might help Sent from my SM-T231 using Tapatalk Link to comment Share on other sites More sharing options...

Belt systems are generally different from transverse and longitudinal engines, even if it is the same engine.
