Default 91 v6 4x4 automatic engine noise 228,000 miles

Does anyone know if this is the noise a timing belt makes before it breaks? Lol!
My power steering is leaking, but I am more worried about the timing belt.
I'm not sure when it was last changed.
Yes I know.
Do you guys think it is related to my code 34, knock sensor?


Thank you everyone!!!

That sounds more like the water pump is going out.

The good thing there is to change out the water pump you will be taking the timing belt off. So, as long as you have a new timing belt and timing belt tensioner in your hand when you reassemble everything, you should be good.

If you have a shop do this, you're looking at $400 to $700. Getting those timing belt teeth set just right is tricky. I had to take my belt back off a few times to get it right, and a number of others on here have had the same issue.

I know the timing belt pain.

As JP said, you gotta remove the timing belt to do the water pump so you might as well do it while you are there.
