There common to break off, you can pick up the replacement drain plug at NAPA and buy a stud retracter to remove the drain plug. if the plug is not leaking, Leave it alone and to drain the radiator, just disconnect the lower radiator hose on the opposite side of the radiator.

Good luck and hope this helps you on your project.

Where do I find the coolant drain plug to replace my coolant on 1997 chevy cavalier?

there isn't a proper drain plug for this type of radiator, nor is there a direct radiator cap either. fun, right?
you can however go about using the lower raditor hose in the same fashion, removing the pressurized overflow bottle cap will greatly aid in drain time and prevent gulping and excessive splashing.
it is a pain to get to without making a mess

I have a 2004 chevy suburban 4 wheel drive in need of changing the antifreeze and not sure where to drain old coolant and to add new coolant.


Not all cars have a drain port. if there isn't a petcock or plastic plug at the bottom right or left side of the radiator, just take the lower radiator hose loose to drain. OK?

[email protected] Chevy Malibu V6 How to drain coolant from radiater. I don't know what procedure to use to open the plastic drain thing at the bottom of the radiater to get the coolant to drain and then close it...


Place a drain pan under the petcock.
Slowly turn the petcock CCW
Be careful to avoid contact with the flow if the car is hot
Open the petcock several turns until the flow is constant.
Remove the radiator cap to allow air into the radiator
once flow has stopped, close the petcock.

Is there anything more we can help you with?

Can't find petcock


Look on the bottom of radiator by the bottom radiator hose it should be right next to it or around on the side of the tank at the bottom, it could be on either side of radiator left or right tanks, its just a little plastic tab you turn you might stand a better chance of finding it from under neath the truck, for myself i always found it easer to just pull the bottom radiator hose off to drain it, but it can get a little messey.

How do I turn the petcock valve on my Chevy S-10 98" to drain the radiator fluid. It looks nothing like a wingnut and more like an "L" shape that takes some kind of key ... can someone help me other than...


Well usually the center is setup for just the square end of a 1/4" rachet (used with a short extention). Look at the end and see it it has a small square hole in it. I'm not sure who told you to take the hose off, and I know you dont want to hear it, but that is great advise. GM petcocks are plastic inside and out. They get eaten up by the antifreeze as it ages and frequently break. Thats major trouble, depending on the break, it could mean a new radiator. The hose is messy, but the way to go. I will not allow the mechanics who work for me to open most plastic petcocks for this reason.

I want to drain my radiator but can't find the drain screw


Disconnect your lower radiator hose...or open the petcock located on the lower corner of your radiator. Be sure to have your cap off.

How do you drain the coolant system on 2003 Impala 3.4 ?


The drain **** is on the lower right "backside" of the radiator. You can't get to this or the lower hose without removing the plastic shroud under the radiator. This has 5 bolts holding this on. Then reach around the back of the radiator and you will feel a wingnut. You can loosen the drain knob with pliers, but a small crescent wrench on bolt attached to wingnut will prevent any stripping. The knob will only need a turn or less to loosen,,,,then you can use your fingers to adjust flow.
