You can try tightening it first but yes it just has an o ring around it that is easily purchased at any auto parts and easy to install but antifreeze will have to come out,or you also can buy a whole other drain plug and try to remove and replace it fast as not to loose much coolant with out having to drain the system. good luck hope this helps you.

Leaking radiator... on drivers side, facing the engine, in the bottom corner, there is a place that appears to have had a also appears to be where the fluid is coming out at... difficult to see...

It's not the drain plug, is it? I don't think there would be a coolant hose there. Sometimes a drain plug will have a short hose to direct the drain downward.
There may also be two lines to the radiator from the transaxle-they are cooling lines to a separate reservoir inside the radiator, to cool the transmission fluid. Examine the fluid and see if it is coolant or transmission fluid. Your radiator may have to come off to stop the leak if it is not a drain plug that just needs a new o-ring seal or needs tightening.

When I crank the car, coolant leaks on the lower driver's side of the radiator. When the engine gets warmed up and the thermostat opens, then the leaking stops immediately. I can't see exactly where it's...

Checkyour hose clamps its likely leaking at one of them feel the back side of the lower hose to see if its running down the hose and ending up at the radiator but if it stops when the t stat opens the radiator is probably not leaking

I need help to find the drain plug for the coolant on the radiator so I can flush it out. Do you have a picture for me to find it. I do apprieciate your help on this matter

Drain plug is located on the driver's side of the radiator, It's common got the drain plug's O rings to go bad and promote leaking after it's been removed due to time and heat.
Your better off by doing what most Techs do by unhooking the lower radiator hose from the passenger side to ensure no additional work is needed to flush out the coolant from the radiator.
Thank you for using fixya and be safe.

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!

Oil and Coolant leak of about 11/2 quarts coolant - 1/2 quart oil per night Leak 1 (Coolant) Appears to be coming from the radiator bottom right corner. Leak 2 (oil) Appears to be coming from the engine...

The passenger right side of the car doesn't have any flanges for cooling system, if that's correct then your radiator has a leak or puncture.

The driver side of vehicle has both the in and out flanges for the radiator. Very common to see leak at the drain valve leaking (not closed tightly). In the same area would be bottom flange of radiator which the composite flange is degrading and causing the leak.

The middle part of the bottom engine compartment is where your oil/coolant cooler assembly just above the oil filter. A loose oil filter could be the cause 95% of the time and 5% would be a bad o-ring from the oil cooler to the oil filter flange.

Vehicle is 1999 T/C Limited (3.8L, V6) Leaking in 2 places.

Hi Briseno,

Solenoid pack leaking,
Cooler Lines to Radiator leaking,
Timing cover leaking,
They suggest changing the water pump at the same time as the lower rad hose, timing chain, and valve cover gaskets. This is because it either looks like the water pump will die soon, preventative measures, or the shop is trying to rip you off for an hours labor.

Either way, I would suggest taking it to a mechanic, unless you're a bit of a handy man.

Hope I've helped, don't forget to rate.
