I have a 2005 ram witha 5.7 hemi and i can not
stop a coolant leak from the waterpump i tried 3x
to seal it. It only leaks when it gets cold at night.
Maybe it's time for a new water pump. I hope you didn't use some of the pour in cooling system sealer, if you did then you maybe in for trouble down the road with overheating. Sometimes a good power flush can help.
It is a new oem waterpump. Thats why im at a loss
Pressurize the system cold, and see if you can locate the leak, if it is the pump then it is a bad new part.
