I have no coolant external coolant leak. But for some reason my coolant in my overfill recovery tank seems to just mysteriously disappear. After about a month the tank will be completely empty and the radiator will be down about 3 inches... I park in my garage where it is always completely dry... but the level drops somehow.

Whats the DEAL?

Coolant leak to oil?
Coolant leak to intake tract?

Oil has always been good. I've never seen any milkyness to it anytime I've changed it.

Got sweet smelling exhaut fumes?

Not that I know of. But then again, I don't really pay attention to what they smell LIKE. I don't remember them smelling any different from any other car'* exhaust.

I thought I should also add. For anyone that doesn't know, this car was overheated severely in Aug 2005.

And I currently run a 70-30 mix of this:

Why did you convert an 89 to Prestone Dex?

Right off the bat, Wrong coolant.

Put your hand over the exhaust pipe with the car running. Pull your hand off and quickly smell the condensation on it. Should smell like gas and burnt oil. Sweetness is coolant.

About time for LIM gaskets?

Yeah, how long have you been running the DEX?

Well its not DEX, its Dex Compatible, and if you read it, it says its ok for many cars, including ones that normally take DEX.

I have been running it since August 2005 as I stated above.
