I am ready to replace the thermostat on my 2000 Blazer, mileage 102,000. I need to lower the antifreeze level in my radiator, but I can't seem to find a drain.

Where is a convenient drain plug on the radiator?

Thanks!

It is normally attached to the bottom corner of the radiator tanks, on some cars you have to take off the splash shield from under the front of the car to gain access to the drain petcock.

You can find the drain at the left botton corner
of the radiator is right under the rubber hose. It is make out of plastic.
