hey guys so my car(02 honda civic ex) 4dr sedan is making this screeching noise coming from the hood and my friend says it was an easy fix something to do with some belts the noise happens pretty much every time i turn the car on. can anyone help and tell me how to fix this? please and thanks

first you can check to make sure the belts are tight....

if they are, it is most likely your alternator, power steering pump, or a/c compressor

remove the belts and see how well the pulleys turn

start the car with the power steering belt removed, does the noise disappear?

next do the same thing with the alt belt removed, does the noise disappear?

i had a friend look at the car and the noise is intermittently but he says the belts are good that its just dust or something of the sort!

If it screeches when you start the car-- then it quits screeching after a little bit, tighten the alternator belt.

does anyone have a tutorial on how to do it ? please and thanks also does anyone know how i can fix this like thudding it gets when it rains it sounds like theres water in the wheel well on the passenger side. when my mechanic last tried to fix it he used a ziptide

Woah, slow down there buddy.

Jack the car up and use jack stands.

Step 6, 7, 8 and 9 show you where you need to adjust.

that seems really complicated ! lol

I know it looks complicated, but it's actually pretty simple, once you get into it. Just make sure you have the wrenches, and jack it up right.

My car was doing this, and it ended up being the AC compressor / Alternator belt. It wasn't because of the compressor, but the belt is shared three ways, and it was loose.

As for the thumping noise when wet, mine is currently doing that... I'll be interested to see what you get.

so i took it to the mechanic and he says the belts are fine and tightened but its still making the screeching noise

its probably one of your pulleys then....power steering, alternator, or A/C compressor

But no answer as to why there is still a drastically wrong noise?

Your mechanic is broken. Replace him.

Rahway09

so the noise wasnt happening when i took it to him and he was like he needs to hear the noise to further diagnose it but i havent gone back. but i have found that the noise happens more when the ac or heat is on and then when i turn it off the noise stops does that help anyone?

That's a given. Gotta verify the complaint for ourselves.

However, if you give enough information (which you already have done) one can take an educated guess as to what the most likely cause is: I still stand by my first reply (clicky): https://www.civicforums.com/forums/p...407-post4.html

(Alternator and AC share the same belt.)
