I found the radiator drain cock for my '01 blazer (v6) on the passenger side towards the bottom (obviously). I had to remove the tire and some of the mudguard material to just get a clear view of it. I cant get it to open though, I think you need some special tool to turn the drain cock-and you will need a small diameter hose or tube unless you dont mind the mess all over your driveway.

its on the left hand side of the radiator but not very easy to get to My apology, it is a 1996 S10 Chevy Blazer instead of a 1999 Chevy Blazer. I need to see a picture or more detail of where the drain plug is located on the left side of the radiator. I have searched and searched and cannot find anything to drain with. Thanks, Linel

Credit goes to the guy who answered a similar question (see the copy and paste answer below for credit). I just drained my 2001 Blazer and this answer is right on. Definitely access through the right front wheel well (behind a rubber flap). ----- Where is the radiator drain plug on a 2000 Chevy Blazer? First answer by 69.250.110.131. Last edit by 69.250.110.131. Question popularity: 19 [recommend question | report question] Answer I have a 1999 Blazer and I was looking for the radiator drain plug as well yesterday. mine appears to be broken but it is located on the passenger side of the radiator near the bottom edgeon the engine side you might have a small black rubber hose coming of of the area of the drain I think this is supposed to make collection of the coolant easier. The drain is plastic and should look kind of like a wing nut. You also get the best access to it from inside the wheel well by moving out of your way a rubber skirt. Its still not easy there is not much room. I have read others have just removed the lower hose to drain the system. I know that makes a real mess.

Look at the bottom or the rear of the radiator Take off the splash guard for easy access to the drain plug.

The drain plug is actually just a screw that requires a large Phillips head to remove. It is located on the passenger side at the bottom of the radiator. The best way to locate it is to find the tube that runs from the coolant reservoir to the radiator and look underneath where it hits the radiator. The plug is easy to overlook, as it just looks like a regular bolt. Make sure the engine isn't hot before you drain the coolant.

Quite easy. All you have to do is drain the radiator, unscrew the hose clamps, pop off the old hose, and install the new one. I'd recommend you buy new hose clamps when you replace the radiator hose. Feel free to contact me if you need more in-depth info on this or any other Blazer-related matter. The email address is in my bio page.

The drain plug is in the center of the radiator on the bottom where there is an access hole. It is blue in color and requires a wide flat bladed screwdriver to turn. Note is is easy to turn also easy to break also.

"Easy"... That's probably using the built-in drain valve/petcock. Bottom - drivers side of the radiator.But then there's fast, and messy - pull the lower radiator hose.See "Related Questions" below for more details on both.

There isn't one. Pretty ridiculous. You have to disconnect the lower radiator hose to drain the coolant, and, believe me, it's not easy to get to. You need to have hands the size of a spider monkey. But it can be done because I did it.

On the older 4.0L Ford there is a plastic shroud directly under the radiator. Remove it (not hard) and you should find the drain petcock. It is easy to spot and is on the passenger side of the radiator.

One drain plug located in the center (bottom) of the radiator. It's not easy to get to but it can be done. If you cant get it just take off the bottom hose on the passenger side of the radiator.

Lie down under the car. On the bottom right of the radiator, you will see a plastic wingnut. Take some pliers and unscrew it. Have a drain pan handy, because it will come shooting out.

The Engine coolant drain plug on a 1996 Mazda is easy to find. Crawl under your car and look at the radiator. If your feet are sticking out the front and your head is facing the back it will be on the bottom of your radiator on the right side.

Go to modulemaster.com and you will find easy instructions and great prices on reconditioned modules.

Being very careful, drill a small hole in the middle of the broken petcock. Using a tool called an easy out, you should be able to back out the broken off part. Take care not to drill sideways and hit the radiator threads.

It is under the bike about 8 inches behind where the drain plug is. It is easy to get to.

What do you mean by "rad"? Radiator? Radio? Which year?The radiator in the classic 900 (1979-93) is easy to replace. Should take only about an hour.1) Remove hood. Drain coolant (drain petcock is on the right side).2) Remove upper and lower hoses to radiator3) Remove ignition coil attached at top of radiator4) Remove two bolts at top of radiator5) Lift radiator out.6) Install new or rebuilt radiator.7) Fill with new anti-freeze/coolant.

Almost all Mazda's have a drain plug in the bottom of the radiator. Easy to see if you just look under the car. You do not even need a wrench. It is a low spot and almost all the fluid will drain if you just open the radiator cap. Almost all moder car will need to be "toped off" a couple of times when you refill the radiator.

UNDER THE PASSENGER SIDE ( USUALLY ) ON THE BOTTOM LOOKING UP @ THE RADIATOR. LOOK @ THE SOLID PART THERE IS A PLUG THAT SHOULD HAVE A SPOT FOR AN ALLEN WRENCH & A WRENCH ON THE OUTER PART. LOOSEN THAT , THE FLUID WILL COME OUT MORE As you turn & pull that plug. JUST A TIP GO EASY WHEN YOU TIGHTEN IT BACK UP. IT WILL BREAK IF YOU GO TO MUCH.

Lift rubber flap inside passenger side (right side) wheel well to access white plastic drain cock 3. Place 1/4" drive rachet into end of drain cock and rotate 90 degrees (1/4 turn) counter clockwise 4. Remove rachet and pull white plastic drain cock outwards (towards firewall) to release coolant Good Luck.

* - 8/1/09 Open petcock on the passenger side of the radiator. This is not easy to do, but it is the enviromently cleanest way to do it. You will need to disconnect everything holding it into place, including the transmission cooler lines. you will need to slightly lift the radiator to reach the petcock. Good luck. - *

Use an Easy out bit, (you'll find at your hardware store). Got mine stuck just yesterday

Any plasic parts cannot be repaired. The radiator and and thermostate housings are easy repairs. The bypass tube in the rear requires the intake system to be removed.
