Question type: Maintenance & Repair

I just had to replace the radiator hose connector
(looks like a k almost), because the old one had a
hole blown threw it. I was leaking coolant and it was
spraying everything under the hood. So now that I
fixed that now when I start it it he car idles strange
and the serpentine belt won't turn the pulleys. What
should I do? I bought this car loved it and the
second day after I bought it that connector blew a
hole in it and now this. Its  been sitting for about 2

One of the pulleys that the belt turns has seized up remove belt and try turning each pulley by hand they should move freely it not that pulley is seized up and what pulley goes to needs to be replaced.

Is it possible that the coolant short circuited a wire or connection somewhere as well? So your saying that the pulley AND whatever it goes to has to be replaced?


Not the pulley itself the pulley can be removed from what is seized up and installed on new part that is bad.


Pulley can be removed and installed on new part.

And if there are multiple pulleys seized up then everything connected to a seized up pulley needs replaced correct?


That is correct but is highly unlikely that more than one part is seized up.
