My Tacoma is Drinking my Anti-Freeze

My Tacoma seems to drink antifreeze. The Anti-Freeze doesn't leak from anywhere but i have to add some to the radiator every time i want to use it. I looked in the radiator and there was a lot of Junk in it so I cleaned it out because I had just put that Radiator in there and after i cleaned it out i didn't have to add any antifreeze for about a week but now the same problem is happening. It isn't leaking its just disappearing.

 

make sure there is no water in your oil

it could be a clogged radiator overheating and the fluid is coming out onto the road as you drive so you never see it. stick a soda bottle under the hood and put the overflow drain hose from the radiator catch reservoir in it so you can see if water is coming out the hose as you drive. if its dry and you lost water then switch and put the drain hose from the radiator into the soda bottle and go for another drive. if you still see nothing in the bottle then idle in the driveway until water is used then confirm nothing is wet, if that is the case then its leaking into the engine so pull the plugs and see what they look like.

is there a sweet smell from the exhaust pipe? that might indicate a head gasket leaking into the cylinders and just being burned off as you drive.

 

check your water pump for build up...
it could be weeping but evaporating before hitting the ground.

That doesn't mean you should disregard any other possibility
including radiator/hose leaks.

any white smoke or sweet-acrid smell emitting from the exhaust ?
a leaking cylinder head gasket could be of issue if so.
Checking each spark plug(s) residual color can be helpful.
If all the plug electrode ends look the same color...
and none are wet looking... then it's probably not a leaking head.

a weeping water pump is commonly found to be a fault.

 

I cant tell if it is a burnt head gasket or not when i run the car and the thermostat opens it smokes but that is the only sign that could lead to the head gasket theres no sweet smell in the exhaust, the oil isnt milky and its not overheating anymore. The car was originally from Florida and didnt have a thermostat in it and when i put the thermostat in it it didnt really change anything.

 

heater core?
