I can't find location of radiator drain plug. A picture or diagram would be helpful.

Here is the procedure: Remove radiator cap, Drain coolant, remove drain plug located at bottom of radiator. Remove upper and lower radiator hoses, Remove electric fans mounting 4 bolts and disconnect electrical plug connection, Remove Hi & Lo transmission cooler lines connected behind radiator and finally, remove upper radiator mounting bolts located on top and remove radiator upward.

Hello. Here a non-photo diagram. Hope this helps!!!

The thermostat is located on the side of the water pump, the water pump is located just above the a/c compressor, the thermostat is fed coolant from the radiators lower radiator hose.
Thermostat :
1. drain coolant and tighten drain plug ( easier method : remove radiator cap, get big drain pan, place drain pan under lower radiator hose to radiator connection, remove clamp, slowly remove hose, allow coolant to drain into pan, now is a good time to remove radiator hose and clamp from thermostat housing )
2. remove thermostat cover / cap ( easiest to get at this when front of car is supported by jack stands and right hand side lower cover is removed ).
3. thermostat cap is held on by 3 bolts / remove thermostat.

You will notice that the thermostat's air bleed hole is pointing up and lines up with notch in water pump housing,,

ATTENTION :failure to install new thermostat in the correct location will cause engine to overheat.

1. install new thermostat to water pump, make sure air bleed hole lines up with notch, install and tighten bolts, install a new lower radiator hose, fill cooling system.

thermostat # 17670-77E00
lower radiator hose #17854-65G20
hose clamp #09401-36403
upper radiator hose # 17852-65G20

Theres no such thing as a diagram, here are the draining instructions, hope this helps...

1-Place a large drain pan beneath the radiator drain plug. The drain plug is located on the passenger side at the very bottom of the radiator on the engine side.

2-Make sure the engine is cool. Open the hood of the truck and remove the radiator cap.

3-Loosen the drain plug. On the 2000 Blazer, the drain plug is a wing-nut type of plug. Twist it with your fingers until the coolant begins to drain.

*To flush the block, once you have drained the radiator, run the engine for a bit untill the temp gauge goes up to normal, then the coolant will have been evacuated from the block. DO NOT leave the engine on, once it reaches normal temp, (this will happen quick) turn off right away, otherwise you'll be forking out a few hundred $$$ to fix the worped heads.
4-Tighten the drain plug with your fingers once the coolant has drained fully from the radiator. Remove the drain pan and dispose of the used coolant properly.
Some service stations will take and recycle your used coolant.
Hope this helps...

depends on what motor you have, it'll either be on the bottom of radiator (you might have to move the cover to get at it) or in the rear of the engine block. if you get at them i'd simply just remove the lower hose from the radiator. just make sure car is compleatly cooled down first.
