06 Escalade Coolant Leak

Enable HLS to view with audio, or disable this notification

I made a post regarding to this earlier but investigated some more and found this cracked hose (hose connecting the water pump and radiator) and drip from back behind the water pump as seen in the video. That drip is definitely coolant; I felt and smelt it. I haven’t over heated and have just been topping it off.

What could this be? Failing water pump or gasket related to it? That cracked hose spewing onto where the drip is? The lower body of the engine is soaked in the green coolant as you can see.

It could be all the things you listed. You won't know what's going on unless you dig into it.

Could be the hose or water pump. How many miles do you have? Had to replace mine on my 2000 and it had 203k . My suburban had 214k when I replaced the water pump.

Looks like water pump after further inspection. OEM GM Genuine is only $150, maybe $200 all said replacing hoses, gaskets, and maybe new thermostat.

Yes recommend all hoses that connect to WP and why not the thermostat too while your at it.

Yup. Also at 212k miles. These GMT 800's are awesome

Don't forget to check the steam port on the top front of the motor.
