Where is this coolant leak coming from?

[JKP]

It's reduced in the FSM because it has the sealant, don't reduce further.

Probably, the reduced torque is to prevent the sealant being squeezed out from in between the threads. Seems like 100 ft# is the proper torque wrench setting.

The added medium, in this case thread sealant, will add greater tension to the fastener if torqued to the same value as the other head bolts (without sealant), essentially resulting in an over-torque situation.

Ok, to do this, don't take hoses off the steering pump to drain any fluid. Just release the stop cock and take a quart or so out. If you do it another way you will have coolant everywhere, and I mean everywhere. Like the entire garage floor the size of the Jeep. NO.

How did you go? I'm almost certain I have the same problem. I've been told it's a head gasket leak — but im not so sure.

Think I'd start by trying to seal the bolt before pulling the entire head to replace the gasket. I'm surely no expert, but to me that looks like the issue described above.

100% agree. If I do pull bolt #11 to re-seal and torque appropriately — will it mess up the other bolts with regards to the tightening pattern/order?

Nah you'll be fine.

Also — do you think she's safe to drive for a little while longer before i address the leak?

It will be fine but also a couple minutes to fix.
