Losing coolant fast. Water pump? heater core?

Been losing coolant pretty fast and having to fill up the reservoir a lot lately. Have noticed a spot on the front passenger lower control arm where I thought water was dripping down. But, after looking closer I noticed its green coolant.


Been doing this for a while and just gotten worse. Probably sped up the rusting too.


Seems to be coming from this hose above the frame. Which imo is a bad design/placement for a run off hose. Whats this coming from? water pump?heater core? something else?

i am actually looking into replacing mine soon.

can you smell antifreeze when you turn the heat on?

Ya I was pretty sure that was it..
When I turn the heat on yes you can smell antifreeze. Which is why i mainly haven't used the heat.

Seen that write up before.Looks pretty involved but straight forward. Thing is, a few weeks ago I installed an or-fab roll cage in my jeep and it was difficult to get in so getting out... can only imagine how hard that would be.doesn't want to budge. Which is leading me to thinking about just bypassing the heater core and going without heat. not the best option but may save me for now and can deal with it later.

bypass would be the way to keep you running.

just don't plug the lines, i think the cooling system needs flow through those lines to keep your engine happy.

that heater is a good idea. didn't think of that. thanks

Been searching about bypassing it and looks like its as simple as finding the hose going in and hose going out and just putting a tube between the two

The two hoses running on the right (passenger) side along the valve cover are your supply and return lines for your heater core. Connecting the two will bypass the heater.

Anybody can take advice if it doesn't interfere with their plan.

The two heater hoses have slightly different diameters.

When you have a choice, buy American.

I see two silver metal hoses then two black rubber hoses going into the firewall in that area. Which ones need to be disconnected? also, do I need to watch out for anything spraying out at me. if anything I'm guessing coolant.
Wonder if theres any write ups on it.
