[Whieroman]

white smoke= badddd unless its condensation of course


Sounds like a headgasket.

Overheating and white smoke? X2 on the headgasket.

[TypeG]

do a leakdown test to rule out a bad headgasket. later.

Headgasket x3

Now it might not be a headgasket. Does it only smoke for like a min when you 1st start it up for the day? But when does it overheat?

No it only smokes when I start the car all the time . And it also shakes a bit when it idles at the start . It over heats when I'm idling at a light but it has a new radiator , thermostats only a year old and I change the coolant like every three weeks or so . The other day before even starting it I checked the radiator cap and all this pressure came out of the radiator :\

I had the same symptom.

It was very hard to start in the cold and if it start the car would idle and sound like a subaru and big puff of white smoke. When it warm out everything idle fine.

when i drive and at the red light my car would overheat. Idle like a mad man. I have to keep filling up coolant every other week.

What i did was replaced Headgasket


check your coolant level.

Check to make sure your fans are working. Make sure you're changing the coolant correctly. Bleed the system of any air. Also check your oil for water/coolant and your coolant for oil.

yeah my fans are working fine i hear them turn on after i turn off the car from a long drive . so im pretty sure thats not the problem . is there a certain way u bleed the radiator to let all the air come out ?

[Whieroman]

Oh this might be important too . I smell anti freeze coolant when i turn off the car does that mean anything ???

Mine don't run after I turn off the car. As far as I can tell they only turn on when I hit the A/C

From my understanding, if there's air in the system the coolant won't flow properly. I think there's a "bleeder valve", but I don't know where. Somebody
will chip in.
