With the drain open nothing is coming out? Did you remove the radiator cap? You can try removing the petcock completely and see if there is any gunk blocking the hole. If there is you can gently poke around in there trying to free it. If that doesn't work you can run the engine with radiator cap on and the drain open, the pressure and heat might free what ever is blocking it. Or if you have access to a coolant pressure tester you can hook that up and pump some pressure in the system to try and get it going. Be careful and stay clear of the drain opening when attempting either of these methods.

How to flush the radiator

After the car has been sitting still for awhile, so that the water isn't hot enough to scald you, open the top vent and put the vent aside. Next, open the stop **** at the bottom of the radiator, and let the fluid drain into a container that you have placed directly under the stop ****. That's so the fluid won't get all over your garage floor. After most of the fluid has drained out, then take your garden hose and fill up your radiator, then let it drain once more. After that, you can put in ethylene glycol ( engine coolant) and maybe an anti-rust additive if the fluid you drained looked brown or reddish. Make sure you closed the stop **** at the bottom of the radiator all the way. When full, replace the top vent, making sure it's also closed and secure completely. All done.

I am trying to drain the cooling system on my 1999 Passat 2.8. I am having problems figuring out a way to drain old coolant from engine block. I can't find the water pump drain plug or any plug...

there is a very small kind of screw just in the lowest part of the radiator, just remove it.
if you don't see this so clear just do it disconnecting the big lowest hose on the radiator,
hope this help you...

Trying to locate the temperature coolant sensor on a 2001buick century

The sensor is on the passnger side of the radiator below the radiator cap. It is black and square and has a single plug at the bottom. It is held onto the radiator by a metal retaining clip. Remove the clip and the sensor pulls out of the radiator. Disconnect the wire by pulling carefully on the plastic lock and pull on the plug. Fluid will leak out to level of sensor. Drain or place catch basin below sensor plug to catch radiator fluid. Sensor can be purchased through a dealer for around $70 US, or Auto-Zone for under $40 US. Your choice.

Hope this helps

Positive Feedback ALWAYS Appreciated :)

Where is the drain for the radiator located

look for radiator drain in underside of the radiator, look at radiator on both sides under neath the van. location will be on under side of the radiator,different models and makes makes it difficult to insure which side,driver, or passenger, just look for a release valve for radiator drain! jack it up,use a jack stand please! look on each side of the radiator for a pep **** valve, that can be turned to release the fluid to drain fluid. hope this helps and thank you for choosing

My 2002 Jeep Liberty 3.7 liter is leaking coolant from what appears to be the drain plug on the bottom of the radiator.I have to replace about 2 quarts of fluid after a short drive.And no one has drained...

The Drain Plug aka Radiator Drain **** has an o-ring on it that does wear-out over time, causing a leak. You can remove and replace these relatively ease. They only turn 1/4th to 1/3rd Counterclockwise to Open and Clockwise to Close. Work on only when the engine is cool. Leave the cap on the radiator to create a suction, decreasing the amount of radiator fluid you will lose. OR drain the Radiator Fluid into a clean container and save for reuse.
Have the new Radiator Drain **** ready for immediately insertion after removing the other leaking Radiator Drain ****. To Remove:
Twist the Radiator Drain **** counterclockwise and pull, continuing to twist counterclockwise removing it.
Immediately install the new Radiator Drain **** by first pushing in and then twisting clockwise to close.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at!
