You would have to explain to me, very slowly infact, how having even the smallest amount of "god damn oil" in your cooling system will make the inside of your Jeep dirty.

Prestone is Green, so why isn't the inside of your Jeep covered in Green dust?

Hmmmm...

LOL! I just read your other thread about Pensoil.

Troll on!

Oil getting into your coolant won't cause dust in the interior - the air that comes through the heater never directly touches the coolant. Plus, coolant/oil milkshake is kinda light brown.

You could always tape a piece of white paper to the heater ducts and see if it gets covered in soot. It also wouldn't hurt any to blow out the vents with some compressed air.

The coolant system will not have anything to do with soot, it is a sealed system. Do you have an exhaust leak? If bad enough the soot you are refurring to could be just that, exhaust soot. Do you live were alot of people have and use wood stoves to heat there homes, garages, workshops,etc? just a thought.

Might want to check the condition of your headliner. When the foam backing on the cloth starts to break down it'll sift through and coat the whole interior in fine grayish/black dust. Hit it with an open palm a few times and see if your hand gets covered in the same dust. Certainly took me by surprise on mine, mistook it for road dust till i took a few trips with the windows closed and still got covered in dust.

magimerlin,yes there are alot of wood burners here,and yes i do have an exhaust leak!bingo,thanks for the help!

michael q ,my headliner is finished,gonna go bang on it like you said! thanks
