Hi all
I have this wierd problem, my altima is loosing 1 gallon of coolant
per week, but only when engine is cold. I can drive for hours without
loosing a single once of coolant, but as soon as I park the car for
the night, it lost a lot of coolant on the ground.

The oil is OK ( no coolant in it ), and it look likes the coolant is
coming from behind the engine.

Any hint what I should look for ?

Your engine coolant sensor is located UNDER HOOD, CENTER, REAR ENGINE
AREA, BELOW THE VALVE COVER, MOUNTED ON LOWER DRIVER SIDE OF ENGINE
BLOCK, It may be leaking there. Drive it and then pull it up on ramps
and get under and watch for drips as engine heats up. (Engine heats up
after it is stopped).
You can buy a dye that goes in the water that will help find the leak.

Thank you Papa Ray.
I didn't know the engine heats up after it stopped. Why is that ? Is
it because liquid stop circulating and engine heat the coolant located
in the engine to more then 200 degrees ?

BTW, the leak turn out to come from the water pump itself ( bering
???). I made it replace ( too tought for me to change this during
winter time at -27 degrees ).

Happy new year Papa Ray.
