Squeal After New Timing Belt

[Everlong-S13]

Just got the timing belt, seals and water pump done on my R34 GTT and now has an annoying loud screech for a few second on a cold start.

I'm gonna probably take it back but in the meantime does anyone have a clear idea which belt is slipping?

its to loose, need to do it up more

If it's just after a cold start, check your alternator belt, it maybe a bit loose.

On initial start, the alternator is trying to re-charge the battery so the load on the drive belt is substantial.

All the belts have to come off to do this job so it makes sense to check them again after the car has done a few K's.

Fan belt is loose, on startup, the fan is stationary and needs some "force" to move it. Just tension it up, piss easy

Thanks for the replies guys, very helpful.

I started the car this morning to see what noise(s) it will make.

It only made a very small squeal this time, however I did notice for a few seconds it clearly sounded like a belt wasn't even turning, which then kicked in with what sounded like the fan belt.

Would this be consistent with a loose fan belt?

My old skyline done something similar and if I revved it, smoke would come out because the belt was loose and scrubbed against the pulley because it wasn't spinning with the engine. Press on the belts and they should all have roughly the same tension. If one is looser than the other, tighten it as necessary. Get a piece of hose and carefully put it near the belts to pin point the sound.

If it sounded like the belt is slipping then obviously a belt is very loose. When the belts are cold they are alot stiffer and are more prone to slippage.

Just an update.

I had inspected the belts while I got a mate to cold start the car.

All the belts were running fine but for a few seconds it seemed like they were all running slow or under load, then after 2-3 seconds it ran normal. It also didn't squeal this particular time.

it depends on the weather, if its a cold start on a cold day it will screech more than other days.

just tighten your alternator belt which is usually the culprit.

it's one of the accessory belts. most likely the alternator belt.
