Bubbles in overflow

Hey guys. I notice something dripping from the car when it is off overnight and gets close to 0F. Looks like it is my lower hose or the thermostat gasket. Need to snug up the bracket and hose. Anyway, so I was checking my overflow it is still nice and full, but I noticed tiny bubbles, when I rev it they go away. My rad cap doesn't look that good either. Can I use my N/A rad cap on the turbo car? It is basically brand new replace less then a few months ago on my wagon so I figure I could try swapping it over. Same goes for the thermostat and lower hose, can I use those items on the N/A car on my SS? Thanks!

I am going to use Subaru coolant the green one, but I am now wondering, should I get that subaru conditioner to? Is it good preventive wise?

The water leak is more likely to be the water pump leaking. Gaskets and hoses don't usually develop leaks unless they have been disturbed. The water pump could also be sucking in air at the same time it lets out water so that could explain the bubbles.

It would be a good idea to have those bubbles checked for hrydrocarbons... by a workshop. If there are traces of hydrocarbons then it's a head-gasket leaking, if no hydrocarbons it is probably water-pump letting the air in.

Ok engine cooled down. Checked and it was just low on fluid a bit. Topped it off via the rad cap, and I replace the rad cap.

Monitor the level. The water pump has a weap hole to let you know when the seals are starting to leak.

If you continue to see coolant down around that area, you need to replace the pump.

Here are pics of where the leak LOOKS to be coming from.

See right where the bolt is? There is water dripping from there with the motor running. Didn't take the pic at the exact time it started dripping.

Uploading a vid. The leak I see overnight looks to be a smaller hose on the bottom above the lower hose. Maybe for the turbo? Going to replace that.

Also noticed my flywheel cover is missing. Is that really important? Looks like I need to remove the crossmember to get in that area.
