What you'll need to perform a radiator flush:
* Phillips head screwdriver or wrench (whichever your radiator drain requires) * Cloth rag * Radiator Flush solution * Coolant * Funnel * Used coolant receptacle Using your owner's manual or your eyeballs, locate your radiator's drain plug. It could be anywhere along the bottom of the radiator, and will be either a screw plug, bolt plug or a petcock (simple drain valve). Be sure you have your used coolant receptacle in place under the drain before you open it up. With your coolant catcher underneath the drain, unscrew it and let the coolant empty completely. If you have a screw or bolt type radiator drain plug, remove it completely. If your radiator has a petcock, open it all the way.
Once all of the coolant has drained from the radiator, replace the drain plug and remove the radiator cap. Add the contents of the radiator flush solution to the radiator, then fill it to the top with water. Replace and tighten the radiator cap. Now start the car and let it run until it gets to its operating temperature (the place on the temp gauge that it normally stays at). Turn your heater on and move the temperature control to the hottest position. Let the car run for 10 minutes with the heater on. Turn the car off and wait for the engine to cool off. If the radiator cap or metal radiator is hot to the touch, it's still too hot to open. *IMPORTANT SAFETY REMINDER: Do not attempt to loosen or remove the radiator cap while the engine is hot. Serious injury can result! Once the engine has cooled down, open the drain and completely empty the contents of the radiator. Your radiator flush is almost finished! Depending on the size of your coolant receptacle, you might have to empty it into a separate container to make room for the second draining. No matter what, never pour coolant on the ground!
Now that you have performed a radiator flush, all you need to do is refill the radiator with fresh coolant. Replace the radiator drain plug or fully close the petcock.
Using a funnel to eliminate spills, fill the radiator with a 50/50 mixture of coolant and water. I'm a big fan of the premixed coolant that's become popular lately, it eliminates the measuring or guessing step. With the radiator filled, go ahead and fill the plastic coolant reservoir if your car has separate openings, again with a 50/50 mix. Tighten all of your caps well and you're like Fonzarelli -- cool!
To flush a Toyota Previa radiator, first drain the antifreeze in the radiator into a bucket. This is done by turning the valve at the bottom of the radiator. Close the valve and add a radiator flush product purchased at an automotive parts store. Follow the directions on the bottle of flush. This usually means running the vehicle for a certain amount of time and then draining the radiator again.

Typically there is a Drain Valve that you manually open to drain the radiator. Caution Don't Do it When The Engine is Hot. You Also Have to Open the Radiator Cap such That the Engine Coolant can Drain from the Bottom of the Radiator. You don't have to put the car up on a jack. Sometimes you will be able to see the drain valve when you open the hood - look down either side of the radiator. You may see it but can't reach it. Sometime you have get under the car such that you are underneath the radiator, and look on either side. The drain valve may not stick out - it may be built flush to the radiator.
At the bottom of the radiator there is a valve turn the valve and watch it go. If you wanna backflush the whole cooling system(good idea) remove the lower radiator hose and your block drain (lowest part of the block usually) and put a water hose into the lower rad hose and flush out all the crap
The valve you're referring to is the radiator petcock. If yours is equipped with one, it will be 2-3 inches from the bottom of the radiator. It looks like a bolt sticking out of the radiator. Remove this and your coolant will drain away. If not, just remove the lower radiator hose and proceed that way. *Remember when flushing out your cooling system, in order to do a complete flush, you must flush in the opposite direction of internal radiator flow. For a down flow radiator (metal fins run vertically), flush from the bottom up, with the cap in place allowing all the coolant and sludge to exit from the upper radiator hose until clear water comes out(best with radiator removed). In order to flush out your engine block, disconnect the radiator upper and lower hoses and remove thermostat and reinstall thermostat housing. Attach water hose to upper radiator hose and flush engine until clean water flows out of the lower radiator hose.
Buy a radiator flush kit and radiator flush additive from your local auto parts store. Follow the package instructions. You can also buy a Haynes or Chilton's repair manual. For the 1984-2001 XJ Cherokee it is highly recommend that you not use the radiator drain valve as it is plastic and rather fragile. Removing the lower radiator hose is faster and easier for draining the cooling system.
You can purchase a replacement flush valve in every do-it-yourself store or you can call a plumber, who can replace the old flush valve and install the new one.
It's a valve that opens or closes flow through a radiator
Easiest way would be to replace the flush valve, otherwise there is a washer underneath that is easily replaced
There is a drain plug/valve at the bottom of the rad. open it and let the fluid out. Then open the cap at the top and flush with destilled water. when empty, close drain, fill with coolant, close cap and off you go.
radiator drain valve is located at the bottom of the radiator, there is an access hole through splash guard.
Most radiator pet cocks are located on the bottom left (drivers) side of the radiator and be warned they have a left hand thread. Some of the newer models I have seen do not have one but could be drained by loosening the lower hose.
The 2003 Pontiac Montana EGR valve is located on the firewall. The valve will be on the driver side of the firewall.
Using your owner's manual or your eyeballs, locate your radiator's drain plug. It could be anywhere along the bottom of the radiator, and will be either a screw plug, bolt plug or a petcock (simple drain valve).

The Easiest way to drain the radiator on your 97 Lincoln is to loosen the drain valve on the bottom (Drivers Side) of the radiator. Make sure the engine is cool, or take precaution not to burn yourself with hot water. Be sure and loosen to radiator overflow tank cap to allow air to enter as the fluid drains. If you are preparing to flush the cooling system, and replace the coolant, you should also replace the thermostat
A thermostatic radiator valve is a valve that is connected to the hot water heating system. It can control the room temperature by regulating the amount of water that goes into the radiator. The valve is able to control this by sensing the temperature of the air.
First, decide if you need a flush and clean or just to replace the anti-freeze with new fluid. You could decide this by looking into the radiator. If you see excessive build up on the internal parts of the radiator you will want to flush with a commercial radiator cleaning solution that will break down the gunk in the radiator allowing for better flow and cooling of the engine.If you need to flush it, follow the directions on the label. Once that is completed you want to drain the system. Do this by placing a catch pan beneath the radiator under the petcock valve. On your vehicle it is located on the bottom, drivers side part of the radiator. It will be facing the engine. Remove your radiator cap to allow the system to breath while draining. Once the flow stops from the petcock valve you can tighten it back up and refill the radiator with a proper blend of anti-freeze and water (follow instruction on anti-freeze bottle)Some mechanics will fill and flush an engine again before final fill with antifreeze, especially if significant build up is present in the radiator. Also, if it easily accessible, the lower radiator hose can be removed to help speed up the draining of the engine. Some people believe loosening the upper hose helps better drain the block but removing the radiator cap will suffice and leaves less to work on in order to get back up and running.
bottom of radiator passenger side there is a valve you have to turn cant miss it. make sure you use a hose or catch pan to catch the old fluid in. also it may be a good idea to by a flush kit from autozone.
More commonly called the 'flapper', it 's the valve that fits over the hole in the base of the tank that you activate when you press the flush lever.
