Question about 2004 Chevrolet Suburban
Posted by Anonymous on
Locate your radiator ( usually bolted to the front of the car under the hood) and look at the bottom and find a little plug that screws off and take it off. Make sure and have a bucket cause there will be a lot of coolant that comes out. then take the bottom radiator hose off of the radiator ( not the water pump) and there may be some more coolant that comes out there and that should be it. If the coolant is really dirty i recommend just taking it to a shop so they can perform a coolant flush and get all the dirt and grime out of your engine before it clogs up.

Not familiar with this specific model, but usually the thermostat housing is on the engine where the upper radiator hose attaches. Remove the upper hose at the engine (drain the coolant first of course), and you should see a couple of bolts that hold the housing onto the engine. There may also be a small bypass hose (about one inch in diameter, and 4 to 6 inches long) going from the housing back to the engine. If so, remove it from the housing as well.
There is a drain on the bottom of the radiator, on one side. It usually has a little handle on it, and turn the handle counter-clock-wise to open it. It may be only 1/4 turn, or it may turn several times.
There may or may not be drain plugs on the engine block itself, some engines have these and others don't. They will be near the bottom of the engine block, just above the oil pan, you will have to be under the engine to find them. There may be one or more, they may be on one side or opposite sides.

Drain from the resevoir by removing the lower hose by pinching the clamp together and pulling, Drain from the radiator via the drain fitting on the bottom...

Not all cars have a drain port. if there isn't a petcock or plastic plug at the bottom right or left side of the radiator, just take the lower radiator hose loose to drain. OK?

SOURCE: location of radiator drain plug
The drain plug should be ner the bottom of the radiator, either on the side or directly on the bottom. It should be a plug about 1/2 inch diameter and usually can be taken off with a screwdriver, but you may need a socket.
Unless you are prepared to clean up a mess you might want to get a small funnel with a tube so you can direct where it goes when it drains.
