Drain pluig on 2001 blazer

I looked, and the plug seems to be on the bottom passenger side, and there is a plastic stopper in it. A regular screwdriver would not work to open it up, did not try phillps head,,and not enought room to grab it with hand. May need a special tool to do it. So, need a way to open the drain **** with out breaking which a shop suggested it was easy to break and to just take off the hose and drain it that way.

    I'm having the same issue - it looks like it takes a special tool. It definately doesn't take any kind of screwdriver or wrench that I have.I can grab it with my hand, but there's nothing to help me turn it, and I am also a little worried about breaking it.

    I'm gonna try the removing lower hose method as described above, When I called a dealer about the tool, he told me that I needed a special "flush machine" in order to get all the coolant out. Was he just trying to sell me a $170 Flush job? He indicated that I'd only be able to get a small portion of the coolant out. I'm looking to solve a pretty major cooling problem by using one of the off-the-shelf flush solvants from my local auto store. Any additional thoughts?

There's no tab on it? That's odd. You should of been able to do it by hand..... Well then I suggest removing bottom radiator hose then. It's a hose about 3 inches thick with a hose clamp on each end. Since it's an 01 blazer, it might not have the usual screw clamp kind. Instead, it's like a spring clamp, sorry hard to explain. You'll see it wrap around the hose with two tabs sticking up. Grab a pliars and squeeze those tabs together. That will loosen the tension. Pull the clamp back by about 3 or 4 inches and then you should be able to grab the hose and start moving it around. CAUTION, make sure your grabbing just the hose, there is a spout where the hose goes on. You brake that spout, your looking at a big repair bill. Moving the hose around and pulling it backwards it should slip right off. If it dosn't, you either don't have the clamp back far enough or the hose is stuck. Yes that happens. You can get a hose pick, it's a like an ice pick but only with a couple bends in it so you can fit it between the spout and the hose to help brake it free. An old screw driver with a 90 or more bend in it should do the trick. Carefull not to puncture hose while using the pick/screwdriver. To reinstall hose, slip it on spout and put clamp back on the way you took it off. Using a pliars, but you might want both hands down there to help ya. Do you best to keep your fingers clear though, you don't want them in there if the pliars slip.

Where do I find the pet **** T valve to drain my radiator

It's on the engine side bottom of the rad., a plastic plug that just screws out, not all the way necessarily. Driver or pasenger side? I'm not sure, have a Buick and the drain plug is on the driver's side. Look for a rounded recess in the plastic on the bottom of the radiator. The plug is inside there. A pair of regular pliers works well, counter-clock-wise to loosen it.

2001 Chevrolet Blazer spark location

Spark plugs are located on drivers side of engine and passenger side of the engine. Follow the distributor wires coming off your distributor cap. You will not be able to easily access all of your spark plugs from the top. For those pesky hard to reach spark plugs it is advised that you go through your wheel wells. You may have to remove the plastic shroud (or cut a hole in it).

How do you drain the radiator on a 2001 blazer

There is drain plug on the drivers side of the radiator at the bottom, but the safest way is to just remove the lower radiator hose on the passenger side to drain the radiator. The drain plug is plastic and it may crack due to time and heat and you'll have to buy a replacement radiator drain plug, for this reason most newer radiator don't come with a drain plug and if you want one you'll have to install the drain plug kit. If your radiator doesn't have a drain plug then you have the newer radiators install already as the older radiators we still being installed until they were all gone and the new ones were installed.
Thank you for using Fixya.

Where is the radiator drain on the 2002 chevrolet blazer?

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.
