Unhappy Coolant leak 2016. 2.4L terrain

Hoping you guys can give me some information. My wife came home tonight and told me that her vehicle was running hot, when I went out to take a look at it the anti freeze was completely empty in the overflow I looked under the vehicle and there was a large puddle behind the front passenger side wheel. I looked everywhere I can possibly think jacked it up and cannot find the leak, the hoses all look good but the frame is wet and thereís a large puddle. If I had to guess I would assume itís the water pump but Iím not 100% sure has anybody else had this problem. There are no visible leaks. It took over a gallon Dexcool l to refill it

It is very possible that it is your water pump.

Because it got hot I would take it to your dealer or mechanic ASAP.
Have them do a radiator pressure test and advise you of what the problem is.
You probably will not be able to do the water pump change yourself, special tools are involved.

Hmmm ... is this one of those deals where it’s buried down in the Timing Set?

I need to check my 3.0L engine for this...

Yup, the water pump runs off the balance shaft timing chain.
The V-6 is the traditional way, just the belt pulley and a couple of bolts.

Yeah ... it seemed I'd already looked this up before - probably in an earlier thread, but wasn't sure.

Another reason to avoid the 2.4L Nox/Terrain.

Couldn't it also be a head gasket? If there is coolant on the ground that makes me think there is a break in a gasket or seal somewhere.
