Chirping Sound In Engine (Video Attached)

[rpand4]

Hi Guys,

 

I am new to this forum. Just signed. Pretty excited to post!

 

I purchased a 1998 Toyota corolla (Seca) 6months ago. The vehicle has done approx 155,000kms.

 

All has been going well, however for the past week or so I have been hearing this CHIRPING sound under the hood. And I have been trying to work out where it is coming from but I am not a hundred percent. It sounds like it is coming from the timing belt/serpenting belt area but what this means I have no idea.

 

So I decided to take a video so that everyone on the forum can view it and possibly help me diagnose the problem. I am new with cars and I am keen to learn, so yet there is the option of taking the vehicle to a mechanic but then I will lose a learning oppertunity.

 

What do you think is this? How should I DIAGNOSE the problem so I can become certain of the problematic part before I go around opening and buying parts?

 

Any advice shall be highly appreciated.

 

THanks

INTERESTING OBSERVATION:

 

When I apply even the slightest pressure on the clutch .....I mean like just tapping the clutch.....the chirping dissappears. Does this mean anything?

Pushing slightly on the clutch pedal will-

 

A )- load the thrust bearing, and if it is dry it may suddenly stop making a noise.

B )- Push the crankshaft forward against its thrust bearings, although that less-than-mm movement shouldn't make any difference to the serpentine belt.

 

Pushing it further down will disengage the clutch, stopping the gearbox input shaft spinning and silencing any bearing or gear noise there.

 

If the noise was just from the belt then touching the clutch shouldn't make any difference. Pull the clutch lever back away from the presure plate and see if it makes any difference.

slipping fan belt maybe?? have you checked them and tightened them up??

 

i have no sound on my comp so i can't listen to the noise so just having a stab in the dark :hmm:

Have someone push the clutch in and out while you're listening for it to confirm thrust bearing.

 

otherwise, it sounds like a pulley squeaking.

take off fan belts one at a time, to see if the noise is still there.

if yes, its a pulley.
