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!

Where is the place to flush a radiator located?

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.

Where is the valve to flush out the radiator on a 1985 subaru GL wagon and how do you get to it?

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.

How do you flush the radiator on a 1997 Jeep Cherokee?

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.
