Where is the drainedge for the radioter
For a 2001 Buick Regal GS 3.8 Liter, Supercharged engine:
First, let engine cool some. Second, locate small drainage hole at the bottom left/drivers side, of the radiator. From the bottom of this small drain hole, go straight back toward rear of radiator, then up about 1 1/2 to 2 inches up. (Have a drain pan or pail handy, to catch the old antifreeze.) You'll find a dark colored drain nut. Use a larger, correct sized socket ratchet wrench & loosen this fitting a turn or so, counter clockwise. Old antifreeze will begin to come out the bottom drain hole. The more you loosen the fitting, the faster the fluid flow out. I wouldn't remove the drain plug completely, or you'll loose control of the draining flow rate.
I just changed my anti-freeze just last week. I also changed the 2 large radiator hoses & smaller 2' overflow hose at the same time, as long as I was doing the job. They had never been changed before. I also used new hose clamps & a small packet of "radiator hose grease", from Autozone.. I drove the car up onto front car ramps to make it easier. I used safety jack stands for extra care. " You-Tube" shows some, "how to videos", that are helpful.
The old hose clamps are difficult to get to. (You'll need a few tools, some time & patience.) To get to the upper clamp, near the right/passenger side of the of the car, near the battery, I removed the outer serpentine belt & tension pully. I then removed the factory installed spring tension clamp, with the help of an adjustable battery pliers. The bottom of this hose wasn't too bad to get to. On the left/drivers side of car, remove black air intake box to access upper clamp. Remove the black metal brace bar, the will allow access to the air intake black box.
I also changed the small overflow 2 foot long hose & 2 clamps, that goes from radiator cap area, back to the overflow white plastic tank, close to passenger firewall. I removed the overflow tank to clean it out as well. I drained the fluid & changed the 3 hoses & clamps. I then placed all removed parts back where they belong, including white plastic overflow tank, tension pully & outer serpentine belt, air intake black box & metal diagonal brace, contacting air intake box. I flushed the system with some Prestone Radiator Cleaner & clean water. Start car & get up to temp., then run for about 10 minutes. Let cool, then drain again. I flushed my car at least 2-3 times after this, until the drain water ran clear.
The best price on a 5 year/150,000 mile anti freeze, came from Wal-Mart. I then mixed about 50/50 with Distilled water, as suggested on the bottle. All went well & no leaks! I took my time and did a thorough job. Good luck!
