post icon scratching noise after replacement of timin belt Sign In

The auto mechanic just recently replaced the timing belt, water pump, AC and alternator belts of my car. When I start my car in the morning, or after it sits and get cold, there is this somewhat loud scratching noise..the noise like a clack-clack-clack-clack? or a click-click-click-click..The noise started a after the replacement of parts and it greets me every morning. After the car warms up, the noise disappears. The mechanic said they don't hear anything or it just normal. Pls help me....

Please; Year, make, model, engine size. Have you left the car, overnight, with the mechanic so he can hear it when cold? How does it seem to run? Was the timing belt broken when you had it replaced, or just did it for maintenance?

Mitsubishi Lancer 2002 - Automatic 2.0L. The car stayed overnight at the auto shop, the mechanic checked it in the morning and informed me that he don’t hear any scratching noise. The engine is running good...replacement of timing belt for 60K maintenance. Thank for the quick reply...

Even though the accessory drive belt(s) are new, one may have a hard spot in its compound or a bit of glazing that will/can make a noise when it’s cold.
The glazing could have been caused by some coolant being spilled on the belt or a bit of grease/grit getting on it during installation?
What you could try doing the next time you think the car will make this noise, is.
Have one of those household pump spray bottles filled with water ready; start the engine; if it’s making the noise; spray a stream of water into the belts.
If the noise goes away or changes (quieter or louder) for a few seconds; then you’ve just proven that the noise is likely coming from the belts.
I don’t mean that you need to soak the whole engine compartment with water; a couple of squirts directly onto/into the belts or pulleys is all that is usually needed.
Now this isn’t a fix, the noise (if this is what it is) will come back. You may need to replace the belt again; along with cleaning the pulleys?
Without hearing this noise or seeing the vehicle; we’re assuming that the technician has aligned the pulleys properly and the belts are adjusted to the proper tension?
