Q: Leaking from radiator drain plug petcock.

asked by on June 01, 2016

I have a 2000 dodge Dakota. After flushing the coolant, the coolant is now leaking from the radiator drain plug. The plug is leaking even though it is fully closed. I asked the dealership for a replacement part however it appears that the petcock is attached to the radiator and can not be replaced. Do I need to replace my who radiator or is there an alteration solution?

Hello. The only other solution you may have is to remove the petcock and install a bolt in its place with sealant. I do not recommend doing this though as it is not a permanent fix. If you want to repair it correctly, then the radiator needs to be replaced. This happens all of the time as these are not opened often.
