how to replace the radiator drain petcock?
Get a large drain pan and make sure the engine is not hot.On the lower part of the radiator you will find the drain petcock.It could be on the left or right side.Usually left.Remove the drain petcock and the coolant will come out.It could get messy.When you install the new one make sure and put thread sealer on it so it won`t leak.Teflon tape or Teflon paste will work just fine.Hope this helps.Good luck.
