Ok... heater blows cold air (i think because its low on fluid cause when i fill it up it seems to work...

but..
heres whats weird.

The top hose is hot.... and the bottom hose is cold...

now... i know that normally the top hose would be cold if the thermostat was stuck because of the flow. but i dont know what it means to have the bottom hose cold... it boggles me

the radiator is new

could this still be the thermo? i dont understand how the top hose could get hot.. also.. the radiator cap is cold.. even when the car is red hot

cold bottom hose is an air bubble. burp burp burp

hmm i dont think thats it...
cause i ran it a day or so ago and it overheated.. so i filled it with liquids (cause it was low and it was fine... then today.. again.. started overheating again... any other ideas?

its an air bubble. trust me. unless your water pump fins have corroded themselves down to nothing(which i've seen), its an air bubble in the bottom of the radiator. thats why the fluid stays cold. its not moving.

ok.. so how do i fix it if thats the issue?

bleed the air out, run it with the cap off, i use a nice little funnel that connects to a cap but u can do it without it
