Default cooling system

My car ej257 engine keeps loosing water.

I replaced the radiator cap just to be safe.

Now i have done a co2 test and no problems. The car is running sligtly warmer than normal. driving 85 degrees. Standing still on hot day goes up to 96 degrees fan kicks in and falls back to 86 degrees.

HG was done back. waterpump and thermostat was replaced.

I have bleed the system of air. And looked for leaks but find nothing.

now the water bottle on the passenger side stays full.
But the metal one on the driver side seems to loose 1/4 cup (or less) of water after a days driving. It also seems to fall to the same level.

I am confused and have no idea where to look.
What advice you have for me?

Check your thermostat... could be sticking and not lettingthe water circulate.

search FIRST, then PM!!!


and the 1/4 cup from the Chalice (the metal one) isn't going into the overflow reservoir (the plastic one) either?

I guess I'm asking, are you certain you are loosing water in the system?

Have you driven it consecutive days without refilling the water level? does it continue to drop?

Default water

When the car is hot the water does push out into the overflow tank...and when it cools down(overnight) it does not seem to suck all the water back in to the system and the "top tank"(metal, some are plastic) takes 1/4 cup.

Thermo stat was replace 3 times with oem and crucial 71 deg C.

Any more ideas?
