I know where the radiator coolant drain plug is, but where can I find the
one on the engine? I want to use distilled water after back flushing the
engine with a Prestone Back Flush Kit and running Prestone Super Radiator
Cleaner through the engine for 5 hours. I will back flush it again to be
sure I got all of the cleaner out. I think I am gonna use the red Prestone
Dex-Cool engine coolant.
Thanks In Advance,
Don't bother using the Dexcool. Just use the green antifreeze.
The drain plugs are on each side of the block, but have you had
a look underneath this engine? Good luck trying to get at
either one of them. The front one is do-able, but the rear
one is not accessible.
The front one is between the oilfilter and starter morter. The back one is
close to the crank sensor. Both difficult to get to if you don't have a
lift. In current engines the green stuff may be more harmful than the orange
What does the car originally come with? I think that in 95
those vehicles still used the green. Aluminum compatible
green a/f has been around for years. I'm not sure if you are
aware of the fact that there have been aluminum components
in automotive engines 'before' 1995.
If it's dark brown I would recommend using a good acidic flush if you DO NOT
have the plastic radiator to clean out the block. There are specific flush
compunds if you have the plastic radiator. Or as us rednecks like to say;
raydidiyator. Once the system is flushed clean replace the thermostat, temp
sending unit, and hoses to save yourself grief down the road.
They certainly weren't all Dex-Cool in '95, anyway, my '95 Sunfire wasn't
and neither was my parents' '95 Grand Am. If it came with Dex-Cool from the
factory, it will probably be pretty much plastered all over the coolant fill
cap and coolant reservoir with references to it, like "coolant does not have
to be changed for 5 years or 100,000 miles if you add only Dex-Cool

I know the 3.4L motor has a problem with the head gasket leaking antifreeze
into the engine oil and siezing up one of the bearings, anyone know which
antifreeze does the least amount of damage though, the green or the red?
Really won't matter. If you have anti-freeze in the crankcase washing the
crank/rod bearings then the color of the anti-freeze will be the last of
your worries. Do you also have oil in the radiator? And, most important,
how long has it been driven this way?
Correct, it's the silica.
I ran some super cheap antifreeze I got from the local antifreeze merchant -
but its also super effective. It was basically recycled glycol mixed with
RMI-25, and I ran RMI-25 with it... worked a treat, engine was cleeeean as
Not that it matters, all that coolant got poured into the paddock after my
accident - pole ruptured the coolant lines n' all... :-(
Oh you mean in coolant getting into the crankcase. Yeah uh it doesnt
matter then what the makeup of the coolant is. The fact that its not a
lubricant is the reason it causes damage to the bearings. I thought the
subject had changed to what coolant does damage in the cooling system.
