Where is my antifreeze going?!
 

ive been putting water in my radiator several times,at one point i had to use a water hose to fill it up.

i cant find a leak,its not going into the oil, me and dad used a radiator pressure tester and put it to 17.5-18 pounds and it didnt drop pressure or show any leaks so where the heck is my water going!? me and my dad are stumped, weve never seen anything eat water like it does but there is no sign of a leak anywhere.

When you get into it its probably lifting the head and pushing coolant into the cylinders.
Time for a head gasket. Get the head check while its off.

+1 for head gasket.

check your trans fluid... also check your passenger side floor up under the dash:tu:

i checked the oil theres no sign of any water or antifreeze in the oil.

ill check the passenger floor under the dash tomorrow.

also theres some like brown or rust colored stuff inside where the cap goes,like on the inside walls, its like brownish orangish rust color, no smell or anything.. any ideas?

sounds like perhaps the wrong fluid was used and it's corroding the system...

thats normal for antifreeze that hasnt been changed in a while.. i would flush and refill the colling system... did u check the transmission fluid for missing antifreeze?

not yet, im going to check it as soon as i can get outside

soon as i get paid ill flush the system,and change the oil,its about time for it anyway.

Is it blowing any smoke like a white color?

no, it smokes light grey at an idle when it first starts but when it warms up it doesent smoke,the smoke is just as black as she can be under a lead foot situation, im going to check the trans fluid and the radiator again here in a sec, i just got back from town.
