coolant help!!

[k-series]

Ok so the other day my heat stopped working so I checked the anitfreeze it was empty...filled it up and after like 5-10min shit was dry empty again....then I noticed when I put some in it was like evaporating from the cap so I changed the container and the evaporating stopped but anitfreeze is still going very quick.....I think when I turn the heat on that's when it goes....Idk what can it be I checked the ax hoses and one was leaking a tiny bit....any help would be appreciated...help me out

fix the leak to be sure... and did you bleed the coolant? its neccessary or it will just evaporate

[Drag0n97]

Pressure test it it could b the radiator my radiator went the plastic was cracked and I didn't know

I have to bleed it since I changed the container?

how would I pressure check it?

Fix the leak. Bleed the system. Buy a new cap. The cap may be broken it's suppose to raise the ATM pressure to raise the boiling point of the water/coolant. It might be broken and not holding the pressure

wait, are you talking about the overflow tank?

Yea where u put the anitfreeze

My coolant used to do the same it was my water pump when the bearing in the pump goes bad it leaks put of the designated openings on the side on the pump trust me only my coolant would last w whole day before being almost empty

where are u located ill diag it for u id start with fixing ur leak ur overflow container has almost nothing to do with ur heat at all its ur radiator that u have to make sure is full overflow only dose wats it says catches the excess or "overflow" coolant wait till ur car is cold take off the cap and let it run as the coolant in ur radiator is moved through ur cooling system add coolant accordingly once its pretty much full and not getting sucked down slightly rev the motor from the throttle body until the fans kick on and check ur heat if u have no heat and ur car is overheating then replace the thermostat if u have heat but car is overheating it could be a headgasket if u replace the thermostat then repeat the bleeding process. u probably leaked it all out and it was never bled properly u could also have more then one leak do this and lmk how it turns out kinda hard to diag online but thats where id start

Dude buy a new radiator cap the shit is stuck open letting the coolant steam out the overflow

No check by ur timing cover to see if ur leaking coolant if u r its ur water pump but fix ur rad first and or a new rad cap

[Drag0n97]

To pressure test it u gotta get a pressure tester u can go to any parts store and buy one u can rent em from advance auto parts is the car overheating at all or just runnin out of antifreeze?!
