Start Up Screeeeeeeech

[95SKY]

Have you thought about the starter motor? mine make a noisey screetch on startup just about everytime?? Just a thought.

[washie]

i had the same problem as 95sky took the starter motor out and lubed it up with some high temp grease and no more noise on start up.

i have this problem right now

i am going to try tigheteing it tonight to see if its stops

you can buy a belt dressing, mine screetches a little every now and them, just spray a bit of this on, stops it for awhile, then re apply or adjust it.

it would probably be better than soap, coke or wd40 etc. because its designed for that exact purpose, conditions the belts too.

you can pick i up at supercheap, or maybe autobahn or places alike will stock it.

sounds like a fan belt...but yeh could be a number of things, but my brother in law has the same noise, but yeh good luck with it

The fix for you...did this last week on my Maxima.

Wet some soap untill it becomes like Jelly then apply to the belt.

PRESTO......no noise.

Cheers

yes I can vouch for that one..Its an old mechanics trick that works...poor bastards are usually slugged $ for it.

My alternator belt used to screach when it was really hot, then if you revved it up a bit or turn it off and on again it would go away. Then I tightend the belts, and they have never squealed again. The belts are in good condition, so I knew that wasn't the problem. After it would squeal, the alternator wheel was hotter than the exhaust manifold, so thats how I knew which belt was slipping.

for mine it was allways the alternator belt that was doing all of the screeching. and boy did it screech..

i ended up haveing the neighbours ask me if it was my car they were hearing in the morning.

tighten it a bit untill it stops then back it off. if it still does it after youve backed it off tighten it up a little more untill it stops again. what u dont want to do is tighten the f**k outa it and root the belt.

Are you sure its a belt, could be a dirty starter motor drive

i hear that screaching noise every few months , i mainly notice it when we get some rain or a misty night , my opinion is it could be moisture getting to the belts? my opinion - im not a mechanic or anything , but i do notice it in those conditions . on my old car i got the same noise and sprayed some wd40 on them , would stop the noise , from happening in winter

I got that problem with my '01 laser. Every time it rains, my belts would squeal but would dissapear after the engine bay heated up.

spray crc on all the belts and start it up. If its the belts they wont screech anymore then you'll know

[Jmaac]

is the screeching like a grinding screech? i.e. starter solenoid not disengaging gear properly?

if its screeching when your taking off your increasing the load on the belts hence slipping so i reckon its them

I need some help too.. Here's my story:

My car was running good, no screeching from under the hood for a couple months..

One morning I start it up..Screeech!!! It lasted for about 30 secs and when the belts warmed up, the noise stopped. It did that after every cold start.

I finally put the car on the lift and put some more tension on the belts.. The noise stopped and all was good for a couple weeks.

Well, my belts started screeching again and so I took it to the mechanic and they put new belts on (from Nissan) and a couple days later took it in again to have them tighten the belts again. It started screeching again, and I had them replace a leaky power steering hose.. (hehe, they told me that was the problem). Now the dang belts are still noisy on cold starts, and I don't know which one.

Could the problem be with the tensioners? Could there be a stripped bolt that keeps coming loose??

I don't know and was wondering if there's a way to replace the tensioners / bolts and if anyone knows where I could pick them up.. I was guessing a Nissan parts store.

I live in Japan and the local Nissan dealer said they might not be able to look at my car because of the mods I have done to the car (i.e. the mirrors don't retract in, haha).. And I don't trust the local mechanic, so I'll do it myself. Thanks for the information, and help, in advance

By the way, I have a '93 GTS25T, with stock engine. I'll post everything in my profile later:) Thanks

Probably completely different problem here, but with the 1JZ Toyota motor (not sure is Nissan's RB is the same) the crank pulley and Harmonic balancer is a 2-piece item, the section that is connected to the motor is metal, the pulley it's self is metal, and there is a rubber shock-absorbing connector that holds the 2 together.

On my other car, the rubber between the 2 metal sections pitted and broke loose, so each time I started the car, it would screach just a little.

Problem with this one (and again, dont know if the RB has the same issue) is that this pulley drives alternator, waterpump and other peripherals, so if the pulley stopped spinning (of came off) it would stop pumping coolant around the engine.

Mine has come off twice now, thus the reason for buying a new car, so not sure if the Nissan could/would have the same issue, but something worth looking at.

My personal preference is that once a belt starts to make noise, it's usually crying to be replaced, or the tensioner is requiring attention.
