Hello, my 2012 KK started a very slow coolant leak less than a month ago. My BIL was the one who noticed it and he took it to his mechanic. They told him that the thermostat housing was leaking and they changed it together with the thermostat and flushed the system. It started leaking again last week, it's possible that it was leaking all along, and I'm pretty sure it is the water pump (my guess is that this was always the source of the leak and not the T-Stat). Also, when I checked the coolant I noticed they used DEXCOOL when they "fixed" the leak
I searched through the forum and found several post recommending that it be flushed again, to get rid of the DEXCOOL, and refilled with ZEREX G05. I'm also having a new NAPA water pump, MOPAR T-Stat, T housing, upper & lower radiator hoses w/ new clamps, radiator cap and serpentine belt installed.
Is there anything else that I should do or check? Thanks!
