coolant leaking?

[35thls1ss19]

If i start the truck and let it run the coolant will drip out, looks like its coming out under the water pump which i just changed 3 months ago. But as the truck gets warm it stops leaking? Then it wont leak till i park in for the night again and it cools down? Where and what shoudl i check? i am lost. After the replaced the water pump it was fine till now....

look around the area where the thermostat housing is , the housing are bad to corrode and cause something like this , and its not impossible to be the water pump again for the record

when my water pump went last time coolant would pour out. this tiem its just drip till it warms up? could still be the pump?

As Scott says check for fluid tracks further up, but if it is coming from the weep hole, the pump is bad. The only one I would use is the one from Northern Auto parts for $85, it is the same manufacturer as who made the factory unit. Also install a coolant filter as it will save your pumps in the future, you wouldn't belive all the sand that leaches from the block.

Yes most of the time they will drip for weeks or months before they start pouring coolant.

but will stop when the truck is warm? that's what confusing me? Shouldnt it leak all the time?

This may be way off base,but could it be a loose bolt?As the engine heats up and expands,making the seal tighter.Just a thought that came to mind.

that was my first thought! great minds think alike but that wasent it

We can guess about where the leak is coming from, or we can go out to the truck and search, dried coolant will leave a residue that is easy to trace with a flashlight. Good Luck, and yes I have seen stranger things happen, metal gets warmer it expands, possibly just enough to stop the leak at the weep hole, or maybe a small piece of debri is blocking it. Many times if it is just dripping you never see it because it get's swipped away by the fan and engine heat.
