I've got 99 5.2L SLT. This winter/spring, the car was overheating and fogging up on the inside - I couldn't keep coolant in it. It was leaking really bad onto the ground and into my passenger side floor.

Took it to a shop - they replaced a hose, did a bunch of diagnostics, and charged me $400.

Now, I'm not having as much trouble keeping coolant in it, and it's not overheating, nor is it leaking that I can see yet - but it's beginning to fog up again, and the blower is blowing smoke (exhaust?) into the car?

Any thoughts? I want to DIY if possible.

 

Found this thread in here... https://dodgeforum.com/m_90992/tm.htm - sounds exactly like my problem.

 

I had tht same problem in my 69 Charger years ago. It was the heatercore and you probably need a new one. I ended up selling the Charger before that was fixed. I had run a bypass system int he interim. The smoke you see is actuallyvaporized coolant and that is why you are having a hard time keeping it in the core. You may or should also be smelling that antifreezr smell in the cabin.
