2014 E350 4-Matic Radiator Drain
While changing my radiator fan and thermostat, I went to drain the coolant and noticed the petcock leaking. It's closed and tightened all the way The image shows what it looks like.
After a while, the leak stops. When I open the coolant reservoir cap, the leak will start up again. When I squeeze any of the radiator hoses, it will start leaking and make a noise. There's a hole there or something.
What are my options? I reallyyyy don't want to replace the radiator because I JUST REPLACED IT.
Thank you!




Get it warranted before you overheat the heads. The coolant circuit needs to hold pressure.
Are you familiar with JB-Weld automotive products... this may help out patch your leak.
