Squeeling Noise at Idle when engine is cold

Truck has 75k miles, I just got it so I'm unsure how long its been going on. It sounds like its coming from the timing belt when I open the hood. The noise is fainter by the time I drive down the street and stop at the first stop light. Is this a sign that I need to replace the timing belt? When do they tend to wear out on these tacos?

 

Probably one of your drive belts. Check if they are loose. Might be a good time to change all of them if you never have. I would tighten them first.

 

try some belt conditioner from CRC products. If that stops the squealing noise than it is one of your belts. Check tension and check for wear.

 

yup, belts are most likely cause, and a pretty easy fix. Check for cracking, etc... too. Replace them anyway if they're still the originals.

Might also be the water pump. Not as easy a fix, though...

 

my '97 2.4 squeals too. more so when its cold, like when starting up. did you ever fix yours? the idler pulley bolt seems stripped, but the belt seems fairly tight. any suggestions for me would be appreciated.

Your profile indicates a 4 cylinder, so you have a timing chain, not a timing belt. So you are fine there. Look at your engine belts as mentioned. I recommend to my customers to replace engine drive belts every 3 years regardless of appearance.
