Where is the coolant drain plug


On the bottom of the radiator. There will be a little plastic valve that looks like a butterfly. Spin this to loosen it, and it will let coolant flow out.

Where is the radiator drain plug located in a 1995 Pontiac Grand Prix?


There is no drain plug or valve on most modern radiators. You have to remove the lower radiator hose in order to drain them.

2001 sable where is the radiator drain?


The radiator drain is going to be on the driver's side along the bottom of the radiator. Best is to remove the lower radiator hose to drain the coolant. Common for the plastic drain plug to break when trying to remove causing you more work and to go out and locate a replacement drain plug. That's why 99% of garages will drain the coolant from the lower radiator hose.
Thank you for using Fixya and good luck

Where is the radiator drain plug located on a 97 chevy 1500 Z71? I'm trying to flush the radiator,but cannot find it.


It's located on the drivers side of the radiator opposite of the lower radiator hose. Note: you may be better off disconnecting the lower radiator hose, it's common for the drain plug to break or the O-rings to split causing more work to drain the radiator. That's why most tech's will drain the radiator from the lower radiator hose, less chance of breaking the radiator drain plug and most new cars now don't come with a drain plug to the radiator.

How do I get to the radiator drain plug? 2003 Astro Van


Great news for you, the best way to drain the radiator is to remove the lower radiator hose. The bad news is that OEM radiator came with no drain plug and you can have one put in after you remove the radiator to drill a hole and tap in a $6.00 radiator drain plug for NAPA auto parts. Good luck and hope this helps. this was a way for GM to save money by one less parts to have make, since most auto mechanic just remove the lower radiator hose to drain the radiator. Good luck and hope this helps. If your luck and your Astor does have one, you can find the drain plug on the lower drivers side of the radiator, engine side.

Radiator drain plug wont seal back up on my 05 dodge ram cummins


I have a 2004 Dodge Ram 2500 and to fix this problem I removed the drain plug being careful not to damage the plastic housing. I drilled through the center of the drain plug so that I would not have to use force to get it out and crack the plastic housing. After you get it out you will see that there is a rubber washer that is used to seal the drain. NAPA sells a drain plug that will work to replace the stock plug. The part #605-1278 comes on a card that says for Ford/GM. but it worked perfectly for me.

Cannot drain radiator in my 2003 dodge durango to flush system


I'm guessing that you do not have a radiator drain plug. It would be located on the bottom of the radiator. If not the next best solution is to disconnect the lower radiator hose. You will only need to loosen the clamp, and slide the hose off the radiator. Don't forget to have something to use to collect the fluid. Keep it off until you are ready to refill. Hope this helps

You can remove the drain plug in the bottom on the radiator.
You can remove the lower radiator hose. Since the vehicle is 10 years old you may want to inspect the hoses for replacement anyway.

) Make sure the vehicle is cool.
) Slightly loosen the radiator cap to release any pressure.
) Re-tighten the radiator cap.
) Place a suitable container under the drain point.
) open the drain.
) Re-loosen the radiator cap again.
) Allow to drain.
) REPLACE THE DRAIN PLUG.
* At this point the radiator can be fill with water and a radiator cleaning agent- run the engine - allow to warm up.
* Re-drain the radiator - .
) REPLACE THE DRAIN PLUG.
) Refill the radiator with water/anti-freeze.
) Dispose of waste fluid according to the local regulations. Some city dumps will accept it. Some parts stores may accept it. Do not pour down the drain or dump on the ground.
