Clicking sound when starting...

[scott61871]

2006 TB EXT 4.2

When I start the vehicle, a fast clicking sound goes for 10 seconds, then stops, then starts again for 20-30 seconds.

Then it goes away until I shut the car off and start it again.....?

Thanks in advance!

Where does the sound seem to be coming from? Have you tried removing the serpentine belt, then start the engine?

Welcome to the nation!! There are a lot of things that could do that, maybe take a video of it?
