No
bad water pump There are min and max lines on your coolant reservoir, are you overfilling(only antifreeze not water) and then when the truck heats up it overflows? Or has the coolant system been bled of any air bubbles(after changing the water pump for example)?
Yes, antifreeze can leak from a water pump gasket.
The water pump will pump coolant(antifreeze & water) through the engine after the thermostat opens up.
It is possible that the antifreeze is coming from a bad water pump. Clean the engine off. Watch it to see where the antifreeze is leaking from, as it could be a hose instead of the pump.
Always use antifreeze. Water does not have any water pump lubricants or anti corrosion properties, antifreeze coolant does.
The weep hole is "an indicator of bad bearings and/or seals" in the water pump when antifreeze starts to drip or run out of it. If antifreeze is coming out the weep hole, change the water pump.
This leak indicates a seal failure and requires replacement of the water pump .
It will leak from behind the pulley that runs the water pump. There is also a small hole in the bottom of the the pump case for that very reason. If the shaft seal goes antifreeze will weep from the hole.
Usually a leaking hose into or out of the water pump (depending on its location), or the water pump gasket.
yes
bad water pump
Probably not. If the water pump is gone it would be a separate issue
