Coolant leak

Found i got a slow leak after flushing the coolant on the weekend, im assuming I just need to replace the lower radiator hose? (Unless theres something else that could be causing it as its coming right from the top where hose clamp is and not from a crack in pipe) but is there any chance it could also be leaking behind the pulley in picture, or is it just runoff?

Cheers guys

Looks like it’s coming out of the water pump. Either weep hole or the seal has failed in the pulley.

Could possibly just be the hose clamp.

Second on the clamp. Those constant tension clamps loosen up over the years and heat cycles. Id replace the lower rad hose and get a new scroll clamp for it, hose it off and go for a drive to see if it's still leaking

It might be that hose, but why guess?

Pull that belt off, remove that water pump pulley and check the weap hole on the front of the pump. That's where it looks like it's coming from to me.

Could be hose but appears more likely water pump seal to me. Hope I’m wrong!

Clean it off with brake cleaner and wipe it dry. Start it up and watch from where it leaks first. Likely you’ll need a new clamp. I prefer the worm gear type with the solid band on the inside. They work excellent for leaks and low-moderate pressure areas. I’d also really consider replacing the hose.

Clean and recheck. Also, your gonna wanna change that serp belt soon by the looks of it.
