drain and refill cooling system on a 92' Grand am

Hi

I plan to drain and refill the cooling system on
my 1992 Pontiac Grand Am.

I have currently the green Antifreeze filled in
and will refill with a 50/50 mixture.

But where is the valve to let the coolant fluid come
out?
I found this picture:

But when I go under my car, I can't found it.

Has anyone here some experience in that?


Regards from Switzerland

That picture is for a GM vehicle that is probably quite
a bit newer then your vehicle. I believe your vehicle will
have something similiar to that, but on the drivers side of
the car. On some of these cars, it's very difficult to see
the drain plug, but it will be there. In most cases, it's at
the bottom of either the left or right tank, usually the tank
opposite where the lower rad hose goes into the rad. And
on the older vehicles, the drain plug "usually" faces towards
the engine compartment. Some newer vehicles (malibu) face
towards the front of the vehicle.

If all else fails, you can always just remove the lower rad hose at
the radiator (often easier "said" then done).

OK, thanks.
I will go under the car one more time and have a closer look...
A friend also told me to remove the lower rad hose, but its look
not very easy...

By the way: Sorry for my poor English.

Hey, don't worry about it! Your English is far, far
better then whatever I could attempt in your language!

I don't know about your 92, but on my 89 there is a drain plug and it is on
the passenger side. However, there is no practical way of getting to it. The
only way I could figure out how do to drain the radiator was to disconnect
the lower hose, not where it attaches to the radiator but on the side that
goes to the engine. It's messy but it works!

Yesterday, I looked for the drain plug one more time.
I couldn't find it. But there is a lot of plastic and metal under
the radiator.
So I think I will remove the radiator hose.
Why you disconnected the hose on the engine side and not on the
radiator side?

Because it's easier to get to!
