High pitch noise on engine side.

[itamnala]

Hi Guys,

Good day! I'm a newbie here and just bought an Explorer Sport Trac 2002 with 62thou km reading on it last week. The problem is, when the engine is running in idle, there is a high pitch sound coming from the engine bay. As the engine rpm goes up, the high pitch sound becomes stronger. It's like two tin metals rubbing each other.

I can't figure out exactly where it is coming from but I suspect the belt or the auto tensioner as the possible culprits. I am quite sure it is not from the engine itself.

Any help from anybody would be much appreciated. Thanking you all in advance.

Welcome to this forum! I've moved your thread into the stock 2002-2005 section. Disconnect the drive belt, and see if the engine still makes noise with only the main drive pulley turning.
