Some aftermarket OEM radiator does not has a drain pitcook.

Spend few minutes to inspect the lower left or lower right portion of the radiator.


Professional shop does not use the drain pitcock because the plastic part is old.

Pro just remove the lower radiator hose to drain the coolant out.

It's more effective and faster.

If the coolant hoses are over 5 years of 60,000 miles then replace them.


If you're teaching this to your kid then take your time and teach them the textbook method.

Overheating so how do i change a thermastat

1. Open your radiator , 2 Locate the pitcock vavle, should be in the lower left corner of radiator aft side, place a drain pan under it open it up let it drain out about a gallon close the pitcock valve, 3 Fallow upper radiator hose to the engine it attaches to a housing that has 2 bolts and possibly a heater core hose running to it you will need to disconnect the upper radiator hose from the housing and the heater core hose if applicable, pay attention to the way the thermostat is facing you do not want to install this upside down they are usually marked "this end toward radiator" new thermostat should come with a gasket make sure all gasket surfaces are clean and free of debris, you may have to remove more than what i have stated and if you arte gonna be maintaning this vehicle yourself i strongly suggest getting a haynes or chiltons repair manual I am a mechanic and i dont work without one

Where is the radiator drain on a 2001 chevy s -10 ?

It should be on the bottom tank of the radiator. The pitcock is usually dirty white in color and will come out by twisting counterclockwise. I suggest loosening the plug in small increments so that you can control the coolant flow as it drains and avoid making a mess.

How to drain the radiator on 2002 Dodge Intrepid 2.7 liter

Warning first...always work on radiator when temperature is low to reduce chance of extreme burn. That being said,
Look on the bottom of the radiator for a "pitcock" valve. It will look like a big wingnut. Turn it counterclockwise to open the valve and the radiator will drain.
If for some strange reason there is no valve on the bottom of the radiator, disconnect the lower radiator hose to drain.

Where is the drain valve on 2002 dodge caravan radiator?

its a pitcock facing the cab bottom of the radiator, plastic flat. once you find the pitcock just put a bucket underneath and turn it.then refill. if you want to flush(run fluid thru to clean it out) the radiator id suggest taking it in. you dont have to flush it every time you change the coolant out.

Radiator flush

The drain plug should be located on the drivers side on bottom of radiator. Should be a flat tab that you can use to unscrew it. Or the faster/messier way of doing it, is to pull of lower radiator hose. Alot faster but alot harder to catch coolant to reuse.
