I have nothing but good memories of my 82 Omni 024. Low on class &
sex appeal but high on value. One of the first cars built with
galvanized skin it looked new when I sold it 7 years later. 1st car I
ever bought brand new and the last car I've owned that required
nothing more than oil, lube, shocks, brakes & tires for its entire
life. OK, 1 exception: The backup light switch broke and cost me
$12.00 to replace. I should be so lucky now.

Carboxylate is organic? That is one of the main ingredients in dexcool.
Gaskets can sometimes be very touchy. They have memories, becoming
accustomed to whatever they are in contact most. Don't ask me why, but many
mechanic friends have told me this from years of experience. In one
instance, they had to redo all the axle seals in a brand new Peterbuilt
because they switched to a synrthetic diff oil a month after they got it
new. Sometimes just little changes can cause havoc.
Take a carbureted snowmobile fo instance. You would be nuts to not use a gas
line antifreeze with it, but use a methyl based alcohol, and you will be
looking for trouble. Ethanol or isopropyl everything is good. Even though
they are all alcohols, the methanol will eventually eat and crack all your
As far as when to change coolant in a semi, they don't go by km's or time,
they go by testing it, for ph, and numerous other variants.
The coolant never goes thru the transmission.
The transmission fluid goes through the lower part of the radiator for some
cooling effect. Some cars have a separate tranny fluid radiator for cooling,
called atf cooler.
The transmission does have coolant lines either going from the radiator to
the transmission and back of vice versa. Sometimes they are filled with
coolant and sometimes they are filled with transmission fluid. It depends
on the make and model of the car.
I always heard some do and some don't. Is that not true? If I am wrong
then I am wrong.
It makes since that the transmission fluid going out of the transmission to
the radiator would cool it as it is getting away from the hot transmission
and the engine. But then it always makes since that coolant going to the
transmission would carry the heat away and keep the transmission cool.
Transmission fluid can enter the radiator and water can enter the transmission.
In this case,
the leaky cooler tank in the radiator will have to be replaced as well as
transmission. One of the common indications of transmission fluid in the
radiator coolant is
the "strawberry milkshake" appearance of the coolant.
this is a break down situation and not normal for any car. [/copied] from:
Nice answer to a question that was never asked.
Let me re-phrase: Name one car that pumps engine coolant back to the
transmission BY DESIGN.
Of-frickin-COURSE antifreeze can get into the transmission when the heat
exchanger in the bottom of the radiator fails, everyone knows that! The
original claim was that some cars have a heat exchanger in the
transmission which recieves engine coolant from the radiator, rather
than having the heat exchanger in the radiator where it recieves oil
from the transmission. I don't believe I've ever read about such a
design and I've CERTAINLY never seen one, and I asked for an example.
Because of that? Don't be silly. Show me 1 mechanic that knows everything.
None of them. Everyone has to learn from someone that knows more hopefully.
That is where I got that information; from someone who knew more at the
time. Someone just posted that the car is an Audi.
