Question about 2006 Chevrolet Silverado 2500HD 2WD

1 Answer

I'm trying to drain the coolant and can't find a petcock. I've found what I think may be the plug I've seen described, but either that isn't it or the screw that is in there is tripped out. The hole on the screw seems to go all the way through, but is just a round hole. I'm really trying to avoid just pulling than lower hose. Working on a 2006 2500 HD 6.0

They don't put drain plugs in the radiators anymore. I know it's not good. But they quit putting them in, in a lot of 2003's. Here is a forum to verify.

I'm trying to do a coolant flush and I can't find the petcock plug on my 1998 Dodge Durango. Please send video link or picture thank you in advance


Some radiators do not have a petcock, and you need to remove the lower radiator hose to drain your coolant.

Is there a radiator drain plug or petcock on a 2009 Chevy Traverse?


no there is a drain , its just towards the center from the bottom outlet hose , it doesn't look too much llike a drain , as its black and is down inside a well (this guides the coolant out) the well is about 3/4 inch deep and the drain plug turns via a tiny wing nut

Car runnung hot not getting water to the engine


not that many things to check here if this happens. Either the water pump is not working correctly (i've even seen the impellers melting due to lack of coolant), the thermostat is jammed closed (which won't allow the coolant to exit the engine and go to the radiator) and needs replacing, or the radiator is clogged up and needs to be cleaned or replaced. In any case here though, you will need to drain the coolant to inspect the parts. Usualy there is a petcock on the radiator to drain it all, but will take a while. If all else fails, you can always unplug the lowest radiator hose to empty the system, but have a big bucket ready cause this will cause the coolant to gush out pretty fast.

I have the proper VW coolant for my 2004 Beetle the instructions say to drain the old coolant but I don't know where to locate the drain.


On the bottom of the radiator, on the inner side, there is a plug called a petcock. It is black and has a little knob to turn. Then the coolant comes out of the little spout on the bottom of the petcock. You turn the knob counter-clockwise and it will let out the coolant.

43@2003 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?

Where is the engine coolant drain bolt on a 2003 2azfe camry? i found the radiator drain but can't find the engine drain plug-a photo would be great


The textbook method is to remove the drain plug on the bottom of the radiator.

Most drain plug is make of inexpensive nylon/plastic and it may fall apart while you turn it.

The professional method is to loosen the lower radiator clamp and drop to lower radiator hose.

Drain the coolant onto a large drain pan and recycle the coolant

Where is the drain plug for coolant system on 1999 Plymouth Breeze 2.4 DOHC. Or do I just disconnect hose at bottom radiator. All I want to flush the system and replace coolant.


on one side of the radiator near the bottom is a petcock. open the petcock to drain. Take the radiator cap off to do this to allow it to vent so it will drain out.
If you cant find it, remove the bottom hose off the radiator. This is messy but effective.
