Hey guys, what would cause my car to overheat at IDLE? I'm talking about like 270hot. All i know is i put in ALOT of antifreeze and it was fine for awhile, and then while idling it went up quite abit. Im thinking about getting a raditor flush and fill.

I have the stock guage, while normal driving now its completely even, like dead center straight across, isnt this to hot? Before it was like a full line below that.

All i know is shes burning up antifreeze really quick, but i cant see a leak anywhere.

 

also, i dont think my heatercore is leaking but it could be i guess. My passenger floor isnt wet, but sometimes when i turn my heat on, i will hear a gargling sound.

 

you will smell antifreeze if the heater core goes out, could be a sticking thermostat, a loose hose, fan not kicking in, if the fans working and you cant find any loose connections i would check the thermostat and the water pump and if both of those are fine then you probably have a blown head gasket.

 

well the fan is electric and runs whenever the key is in the ignition, i HIGHLY doubt its a blown headgasket considering when its filled with antifreeze, everythings fine. And the water pump went out about 2months ago and i had it replaced at a shop. So, with that being said, i guess i can have the thermostat changed, and have them flush and fill the radiator

 

ok, i was thinking you were losing fluid, if the thermostat doesnt fix it then i would look at just buying a new radiator. its not very hard to change and flushing it is fine but just not as good as a new radiator.

 

well, im pretty sure i am losing fluid, but i will have the mech look at it.

 

its just with how well my car drives and performs, i really dont think i have a blown head gasket, i guess i could tho.

 

any specific radiators i should buy if mines bad?

 

I hope your not pouring straight antifreeze/coolant in.... Water is what cools the cooling system... coolant keeps it from boiling

 

soooo what do i pour in the radiator, im unscrewing the cap, and putting in a 50/50mix of antifreeze.
