AUDIO INCLUDED! Squeel while starting, 2001 Pathfinder. Cause?

[path01]

So here is a lesson boys n girls. That old couple that took great care of their vehicle are likely just really good bullshitters.

Ok, so ive got another issue. Only happens when engine is cold, so several hours must pass. Only does it for me when i go to start it overnight. It also seems to crank a bit longer if and only if it also squeels.

COLD START with Squeel

Warm start (after driving it for 4 miles, turning engine off for 10 minutes and starting it)

Any ideas?

My same year has started doing this as well a slightly shorter squeel for mine though, on a cold start.

[path01]

the squeal length is proportional to how long it has been sitting. So the one I posted is after about 12 hours. After 3 o so hours sitting it will squeal but duration is less.

pretty sure it is your tensionner pulley. Either the one for the AC or the other one (don't recall for what)... Mine did the same thing, up to a point where it would only go after 10-20 seconds....

Ok. Squeel when cold is gone.

He tightened the alternator drive belt. Is there another name to this belt? Can someone provide a part number? Which tensioner provides the tension for this?
