Hi all,
It's finally time for me to replace the corroded freeze-plugs in my engine. However... I want to make sure I do it right, and replace as many as I possibly can myself - with the engine in place.
'95 S10 Blazer, 2WD, 4-Door, 4.3L V6
The two I can see are one on the drivers' side bottom of the engine.. and one on the passenger side - almost opposite the drivers' side one... but up under the starter motor. These both have rust around the edges, and a nasty green anti-freeze ooze on the bottom edges.
I've read that their may be one under the bell housing ( will pulling the tranny give me access to this? or is it an engine pull?) Are there orthers?
Thanks,
Rex S.

There are two on each side (the ones you see, and then one behind each motor mount) and then there is atleast one on the back of the engine. There are two large plugs in the back, but I believe the upper one is just an oil seal for the balance shaft bore.
Here's a view of the back of the engine:
And here's a view of the driver's side of the block:

Thanks Kyle,
The pictures are priceless in helping to locate the plugs.
Ya know... I just had the tranny replaced (with a rebuilt) last month to the tune of $1700... I know it's probably futile.. but I wonder if they'd remember or have marked/documented if they noticed a corroded/leaking freeze plug... I suppose a quick phone call tomorrow may answer that question.
As for the ones behind the engine mounts... Arrgh. I'll get up in there with a mirror tomorrow to check their condition. Maybe... just maybe I'll be able to see them.

With a flashlight, I was able to glimpse the drivers side freeze plug behind the engine mount. It looks okay... (whew!) The passenger side.. well, too much stuff in the way to even THINK about seeing it. However, a good sign, is that I see NO dripping corrosion below where the front passenger side plug should be.. like I see on the rear ones.
Thanks again,
Rex S.

Are you sure that teh two in the rear are freeze plugs. I believe the top one is for the balance shaft, and the bottom one is for the cam.
