Bubbles in my coolant - Head gasket diagnosis
Hey guys, working on diagnosing to confirm or deny head gasket problems.
Been fighting overheating for a while, this year hasn't had any problems, but I did heat up the other day so I'm back at it. Already completely overhauled the cooling system since last summer.
Anyway, no noticeable coolant in oil, no weird smoke, so I went to the other options based on this website: http://troubleshootmyvehicle.com/jee...-head-gasket-1. Read about checking for bubbles in the coolant, so I took off my radiator cap let it run to temp and watched. Saw bubbles. My question is, based on the video I have uploaded, is that the kind of bubbling I should notice if there is compression leaking into the radiator, or just air in the system?
I picked up a compression tester today, so I will be checking that next.
Here is my video I recorded:

I did a flush and fill a few weeks ago actually. I was looking around and it does appear the thermostat housing is leaking a little bit on the bottom. I'll get a new gasket tomorrow probably swap it out and check again.

Get one of these:
It will tell you if those bubbles are exhaust gases. If they are, you have a cracked head or blown head gasket.
If you don't want to buy one, see if you can find a local mechanic who has one and will test it for you.
