Ok, no heat, yes no heat.. hehe...

My car's heat isn't working right,
I first thought my car wasn't warm enough
then even my temperature needle is at the middle
I do feel heat coming out when I drive, once I stop for the lights or idle, there was no heat, or sometimes only abit warm air....

so what seems to be the problem??

Also, my car is overheating after I boost for little while, first gera and second gear boost only.. then over heat...
I don't know if this overheating is related to my heat problem..

but i certainly need some help, and I am afraid the overheating is due to blown headgasket...

help plz

thank you

Ok Do you have coolant?
your heater might be core cloged.. or just gone

Is your car kinda acting funny like missing or something... while idling, normal driving?

TurBoXBirD16

yes i have coolant
i actually checked my oil and coolant today beforei started driving

hmm... sometimes my car does idle funny SOMETIMES....
the idle drops really low sometimes..

and... the heat only doesn't work sometimes..

so.. how do i check if it's the heater??

would the heater actually cause my car to overheating??

thank you

u probably have a air bubble bleed the hoses

The same thing happened to me and my radiator and overflow resovoir were bone dry. Symptoms included wild water temp from hi (at idle) to low when driving (guess cold 10 degree air was cool enough to cool the radiator). Then idle would hit 2000 RPM to heat the car since it was too cold. All the while the heater did not work. After filling up the radiator all was back to normal. Make sure to check the rad and not just the resovoir (when the engine is cold and not on of course)

i am pretty sure there is no air in the radiator..

when i refill my radiator, should i have my car running???

i am 90% sure that I did the right step to fill my radiator...

thanks

ace1875

no...

the water in the car moves so fast that it sucks the water needed from the resv and pushess air out.

when you say it sounds like it misses do an early oil change and see if you got coolant in it too cause they don't mix.

TurBoXBirD16

yes that's what i am going to do after next week (reading week coming)

hopefully they don't mix, if they do, it should be the HG, right??

if they don't mix, what can be the problem??

thank you

civura R

ok if it pushes it all out by its self y is there a valve to release the air.
just because u fill teh radiator right that doesnt mean the hoses filled up right chek to see if all teh hoses feel teh same temp.
turn teh car on let it run for a lil turn teh heater on and feel teh hoses if 1 feels colder open teh valve till all teh lil air bubbles dissapeer.
a head gasket wouldnt cause ur heater not to wrk .
does ur fan blow thru the vents ?
what engine are u running ?

TurBoXBirD16

i remember both hoses have the same temp.
my fan is working

it's a Greddy T'd Sohc

well then does heater not working affect my car overheating??

civura R

it can it can affect ur thermostat if there s a airbuble by ur thermostat it wont heat up and open
have u over heated it b4
if u have a blown head gaske t u can also chek ur piping to see if theres water in there. if u have a semi open exaust

i dont' have a half open exhaust, so i can't tell, probably checking the oil is the only way for me
BUT I THINK, if it's the HG, even if i don't boost, it would still overheat, right?? but i never did if i don't boost

It did overheat before after i boost...
and the Heater problem has occured before too, but I just didn't check it seriously lik i did today...

I put my hand to feel it while i was driving for half hour

so... what do i do now??

for the heater problem, what can i check??
for the HG problem, i will need to check the oil, right?

thanks very much

I had a similer prob once.... car would put put heat, had coolent, and the car showed it was overheating. The hose that went into the heater core was pinched. After I fixed that the car still overheated cause of an air bubble. I drained the coolent then and refilled, everything has been fine since.

check your thermostat it may be stuck open.

TurBoXBirD16

that's what i thought too...
got to check it out next week.

So, here is what I would do next week:
1. Compression Test
2. Drain oil and see if there is any coolant in it
3. Check my thermostat??


Well, if all these were checked okay, what else can be the problem??

thank you

I am just asking this coz I want to know what else to do right the way nex week

gohandbz8

Just a hunch but I think you should check your water pump while you are at it. I had an overheating problem once too when i was driving above 60mph. Had the water pump changed and all is well.

TurBoXBirD16

how should i actually *check* the water pump to see if it's fine?

Take your car to a shop to have a pressure test done on the radiator. You will find out if there is a leak in the system. The leak could be as simple as a broken hose (which I doubt would cause a car to have no heat) to a minute crack in the heater core.

Do you get a film of antifreeze on the inside of the windshield when you turn on the heat?

I really hope it's not the heater core or else you'll be in my situation, um three months ago:


I would suggest flushing the system.

CoolKat

have u checked yur fuses? my heat wasnt working a while back ago and i checked the fuses and they were blown, after i replaced it all went back to normal.

TurBoXBirD16

there is no file of antifreeze when i turn on the heat

my coolant level has been staying at the sam level, doesnt look like it's leaking,

and my heat DOES work, but it doesn't work when idleing, so i doubt it's the fuse, i will check it tomorrow though

i am more concerned about the overheating problem than the no heat problem....
i don't want my HG to go... damn...

BlackDeuceCoupe

^ What he said!

BlackDeuceCoupe

Smoking gun! You got air in your cooling system. If you don't mind me quoting myself...

BlackDeuceCoupe

Read and heed!

TurBoXBirD16

alright then.. sounds like it then

well, then can somebody explain a FULLY instructions of how to refill or flush your coolant system??

thank you !

Oh by the way, wher the hell is the hose going into the heater core??
