i searched and couldnt find any good info.

so i was driving today right when i got home my car temp guage went to max. and white smoke started coming out and looks like anti freeze spilled from under the car.
would that be the thermostat?? Please let me know what to check and what to look for. also i am like 1000 miles over the oil change could that have anything to do with it?? i had an appt for tomorrow for the oil change. the oil level is good just a little old. please any info or help is welcome!
thanx ahead of time!

 

Sounds like Head gasket..

 

IF the white smoke was coming out of your exhaust

 

no not exhaust just under the hood
it pretty much was radiator!

 

Could be the oil, as long as it running fine now just take it easy and watch the temp.

What color was the spilled juice? lol

 

Whoa... infiniti of Lisle will take care of you!

 

so i changed the thermostat, and the damn thing is still over heating!
Cmon what else could it be guys??
water pump?

 

I had a similar problem before in my old car, i was driving and white smoke was coming out of my hood. The problem is most likely your radiator cracked or something, thats why you're leaking coolant. I would replace the radiator. That's what happened to me.

 

Wait, what? Why would the problem be your thermostat or your engine oil? If coolant was spilling out from your engine, then definitely it would cause the white smoke you saw.

It sounds like you have a coolant leak somewhere. Maybe one of the coolant hoses fell off or there is crack in the cooling system somewhere.

You should first find out where the white smoke/leak is originating from, and then go from there.

 

def a coolant leak. the firs places to check would be your upper radiator hose. the clamps sometimes give out and leak. also check the radiator seams for any sign of coolant

 

start simple: look for where the leak came from.

it could be something quick like a loose radiator cap.

 

I think it's the water pump... had the same problem with my old car and it was the water pump.

 

How many miles? That might determine if the water pump was in need of replacement.

Don't drive the car with it overheating. Source the leak ( with it blowing out white smoke, I'd say it's leaking near somewhere hot ), repair it ( be it radiator or hose ), refill, and make sure to bleed the system.

I had to repair all the coolant hoses in an NSX, so the G35 can't be that bad.

It doesn't sound like headgasket. I'm not sure about G35s since I've only owned mine for about a month, but if there's a coolant overflow reservoir, watch for bubbles in the reservoir and check your oil when it gets changed by the shop to look for signs of contamination.

 

the car has 95k miles on it.
Yeh i havent been driving it. i changed the thermostat, and when its stopped the fan turns on and everything is fine. once i take it around the block it starts going up and my pops took it out and it overheated again. dammit i dunno wtf is goin on guys!

 

sounds like a coolant leak... check the hoses like others have stated, then the radiator.
