There should be no fluid in this area if the drain cock is working properly.

Car radiator drain plug leaking.

Now when i put it all back together the plastic drain plug in the radiator leaks. There is a steady drip about 1 every second. In many cases the radiator drain cock is plastic and can fail due to heat and age over time. It was sitting out and dry for a couple weeks.

This is a short tutorial video on how to replace your radiator drainage plug. After flushing the coolant the coolant is now leaking from the radiator drain plug. Wash the radiator with a hose. While replacing my water pump i removed my radiator and had it flushed.

I asked the dealership for a replacement part however it appears that the petcock is attached to the radiator and can not be replaced. If you suspect there is a leak and you are able to physically inspect the drain cock check to see if there is leaking coolant around the radiator drain cock. Because the automatic cooler lines that goes into your radiator is a separate system inside your radiator. Mine snapped off because it is plastic so i had to figure out a way to replace.

And if this auto trans cooler section of your radiator is leaking then you have issues with the radiator. Use a hose to spray the radiator and surrounding components so you can know for sure that any new coolant you see in the engine bay after you start the car has leaked since you washed it. The plug is leaking even though it is fully closed. Common causes are the oil pan drain plug oil filter or gasket or oil spilled on the frame while replacing the oil filter.

Check the fuel hoses and lines fuel filter connections and gas tank. Never drive a vehicle that has any type of fuel leak.
