The easiest way to flush, if radiator is left in the vehicle, is to have the car at normal operating temperature, open the radiator drain, and put a garden hose into the cap opening. Turn it on till as much water enters the radiator as is leaving the drain. Run the engine as you are flushing, and run it till the water runs clean out the drain. Then shut off and refill with a 50-50 mix of water and antifreeze.
If you take the radiator off, you could run the hose into the bottom hose fitting and let it drain out the top hose fitting or the radiator fill neck. A simple back flushing method that may help dislodge and flush out any particles-but the first method should work well enough if your radiator is in good shape and not clogged up with rust and scale.

Im trying to flush the cooling system on a '97


Not positive about that engine, but the usual method is the heater inlet will come off the cylinder head somewhere and to the firewall, and the heater outlet (the return hose) will be at same place on the firewall and go to the water pump, very close or at the fitting where the lower radiator hose attaches to the water pump inlet.

Need to flush the water in radiator


Variety of chemical products available at any auto parts store you can use. Follow manufacture's directions. Basics are (with the engine cold) to te enough space in the radiator that you can add the product. Add product and close rad cap. Start engine and warm it up (again follow manufacture's directions) to that the heater core also gets flushed. Now open rad stop **** to drain radiator into disposal container. Fill with clean water. I like to run a hose into the radiator with the engine running, stop **** open and draining and flush it clean after using the chemical flush. Now fill with a 50/50 mixture of the correct antifreeze. Operate the engine until it is at operating temp and let it cool and then recehck the c oolant level. Some cooloing systems will hold a lot of air making them troublesome to cmpletely refill. It is not a big deal as long as you go back and check the coolant level. Use caution if opening an hjot radiator as the hot coolant or steam can blow back n yhou and scald you. Better to always let engine cool down before opening a radiator cap and alsys use a rag to protect your hand when opening a radiator cap. Never add coolant or water to a hot engine unless the engine is running as you can crack the block if you do. There are flush kits that involve cutting a heater hose (not to be confused with a radiator hose) and inserting a fitting that you can connect a hose to to assist in flushing and filing your radiator. .

Trying to flush radiator, where is plug in block, or can I just take bottom hose off radiator, to drain all coolant.


go to auto zone/ O"rileys and buy a flush kit, it is a kit that allows you to cut, a heater hose and install a TEE with a cap on it, the cap end is also the hookup for a water hose, wait until the engine is cool, cut the hose install TEE, hook up water hose, remove radiator cap, turn water on low, crank engine and flush until water is clear, reinstall cap and your block,radiator is flushed, don"t forget to put in coolant

Should I back-flush the system?


I would not use any Super Sealer of Stop Leak, this is just a personal preference due to all the trouble I've had when dealing with the consequences of that stuff later on down the line.  I would definitely back flush the system with the kit to get any nasty stuff out of there so you know you are working with a clean system.  I'm not sure about the A/C system though.

I have a 2002 Pt Cruiser, the heater sometimes works. Could this be a sign that the radiator needs to be flushed? Or thermostat needing replacing.


A couple of things. Simplist is to flush & refill the radiator. Collant level could be low. Mine was doing it mainly when stopped a lights or at idle speeds. If I reved the engine around 2,ooo RPM, it produced heat. Once I flushed and refilled the cooling system, problem went away. Good luck!

Radiator flush


Drain plug is on the bottom of the radiator. Should have a tab for the plug. PLUG DOSN'T COME ALL THE WAY OUT, you're only able to twist it so far. IF your confused, just undo lower radiator hose and have a big bucket. The anitfreeze you put in your car has to be a TOTAL mixture of 50/50. You can buy premixed 50/50 for a HIGHER price! If you don't want to pay that much, you can get STRAIGHT ANTIFREEZE. If you have an extra gallon jug around the garage, fill half with water and half with STRAIGHT antifreeze and tada! You got 50/50 antifreeze. Hope this helps ya.

How do i flush a radiator


go to auto parts store and get a flush kit,

cut and insert the "T" from the flush kit on the heater hose outlet or inlet.
make sure you are cutting into the heater hose coming out of the firewall heater area and not a large vacuum line.
if your not sure ask a mechanic.

connect the kits anti syphon to water hose and connect to the T you have installed ,
open the radiator , and flush very slow if engine is hot , or wait till engine is cool as a very cold flush can damage the engine.
