Coolant leak

Got a good bit of coolant coming down from drivers side around the hose and off of the gearbox bout to get out there and start tracking it down.

My truck is currently in the shop right now for a coolant leak on the drivers side. It ended up being that hose under the degas bottle where that plastic fitting is where the hoses join up.

Mine only leaks where the is pressure in the system, so i had to get the truck up to temp before it'd start leaking. I went through about a gallon every 2 hours in run time, so it was a pretty decent leak.

Look there and also on the underside of the degas bottle. There could be small cracks.

Drivers side of the water pump housing. 1" hose and possibly a bad clamp. Where mine was.

Coolant leaks can kill your FICM in short order so you will be glad you found it.

It shorts out the electrical system? I'm trying to pull the car tube now giving me some trouble got the clamps loose. Do I just yank on it a good bit?

A leak can end up hitting the FICM and shorting it out if it gets enough coolant on it, it will leak inside.

CAC boots can be a bear sometimes, try to pry the lips up and rotate the tube a little bit.

Just to be clear the waterpum is right below the thermostat were the lower radiator hose goes into and there is another hose that goes into it. So there is only two hoses that go into the waterpump correct?

Seems like it could be coming from were the lower radiator hose is secured to the radiator by those plastic clips as there is coolant all in there and when I push up on it more comes out and nothingn above that point is wet

I'm assuming you have the banks cac tube setup?? Those are big for sure. Gotta wrestle the crap outta it to get it apart. It will NEVER blow off,, but dang!!!! Let me say I freakin hate the banks setup. It's nice I guess,, as long as you never have to touch it. Which you got a lesson as to why I can't stand aftermarket stuff.
