Yes it will give you room to get arm up in there to work.
There are no drain plugs on a Lacrosse's radiator. GM stopped them after 2003 model year. To drain the radiator, you'll need to remove the lower radiator hose.
DRAIN PLUG IS ON RIGHT SIDE OF RADIATOR. YOU NEED TO REMOVE THE PLASTIC PROTECTION UNDER THE RADIATOR TO GET TO IT.
The bottom radiator hose is the drain plug. I guess the designers decided that there was no need for a drain plug any more.
Generic answer.Most drain plugs are at the lowest point of the radiator.if no plug is fitted, you will need to remove the bottom hose to drain the radiator.
I have a 2000 Pontiac Grand AM and radiator drain cock is located at the lower/front (not bottom) at the curbside of the radiator, you will need a hex key to back out petcock.
When you open the hood you will see a plate that is above the radiator. (the hood latches is mounted on it) you will also see a bracket that is monted to the top of the gill. You will need I believe it is a #25 star bite for some of the screws. You will be able to screw the drain plug back in from the top. Good luck.
In order to flush the radiator you will need to remove the lower tray to access the hose. Unscrew the drain plug attached to the hose and let the radiator drain.
The drain cock is at the bottom of the radiator above the splash shield. Either you will need to remove the shield or you will need a piece of 3/8" hose about 12 to 14 inches long to attach to the drain tube.
Look closely at the radiator. Check the bottom corner of the radiator that is opposite of the lower radiator hose. If there is no drain plug or petcock, then the coolant will need to be drained by removing the lower radiator hose.
I'm not sure about this particular car but not all radiators have a drain plug. If you cannot locate the drain plug then simply remove the bottom radiator hose to drain the radiator. Keep in mind that you may need to replace the hose clamp if it has the one-use factory style clamp. The drain plug is directly below your upper radiator hose at the bottom of the radiator.
Sediment blockage. You need to have your radiator power flushed to get all the build-up out.
Drain the antifreeze.
