UPDATED in BOLD

Hi guys. I'm attaching some pics and could use some advice. I "think" I have one small hose leak coming out of the outlet pipe above the water pump. I have a few questions. I lifted the SC cooling lines and felt nothing but dry on the underside of them. Underneath them, there are two lines coming out of the thermostat outlet pipe water pump.

1) the line on the right appears to be the culprit. Is this the return line to the reservoir or the outlet? Since it's attached to the thermostat outlet pie, I'm going to assume it's the reservoir return line

2) Should I be able to just replace it without having to drain coolant. Just lift the front end. Agree? I found the hose part number

3) Where does the line on the left go? I see it runs along the SC then drops behind the engine. My health is preventing me from getting under the vehicle and investigate further. As it appears to be weak from age too.

The parts diagrams for the SC Thermostat outlet pipe only show the one line next to the temp sensor, however, there are clearly two

Thanks in advance

 

1) the line on the right appears to be the culprit. Is this the return line to the reservoir or the outlet? $57 for this return line if anyone is interested.

I opted to cut 3/4" off the end and reattach as I want to be sure this is what's leaking. I drove around for 30 minutes. As you can see in the initial pics, there is coolant on the splines of the water pump. I cleaned those off and they are still bone dry. I will add more coolant now and recheck.

2) I found the hose part number and will replace once I confirm this is the leak. If it isn't, I'll get a pressure tester

3) Where does the line on the left go? I see it runs along the SC then drops behind the engine. My health is preventing me from getting under the vehicle and investigate further. As it appears to be weak from age too.

The parts diagrams for the SC Thermostat outlet pipe only show the one line next to the temp sensor, however, there are clearly two. Still stumped. If anyone knows, please reply. I've attached to blow up and you can see only one outlet (per the diagram, this is for the SC 4.2 so I'm stumped).

As you can see in the pic on post 1, there are two lines.

Thanks in advance
