Nissan 200SX funny noise

[soccerislandbouy]

Whenever I start my 1998 Nissan 200sx SE-R I hear a funny vibrating sound for about five seconds then it goes away. Does anyone know what that noise is related to?

Where does it come from?

It's probably just something moving around while the car goes through the early stages of warmup mode when you first start it up. No worries.

I have checked while someone starts the car and I dont see nothing moving around. I think it comes from somewhre around the belt area. Do you think a belt need adjusting?

[nametakennow]

Eh, doubtful, as you'd probably get noise all the time.

Just because nothing appears loose doesn't mean it there isn't anything loose. A little vibration is usually the issue.

Where around the belts? Lower or higher?

Have you worked on it recently? Maybe a you dropped a screw or tool...

lower no I have worked on it so i dont think there's a screw or tool there. Do you know if anyone had the problem before?

Thanks Though

Probably the timing chain until the tensioner tighten ups. Tensioner might need to be replaced.
