You have to bleed the coolant system completly for the heater to work properly. If not, air bubbles will stay in the heater hoses (mainly the hose that runs right in front of the alternator).

 

o2/coolant are not related.

If you had your low coolant light come on and now you dont have heat. I'd say air is in your system.

As far as your temp your fans are coming on which is why in traffic you'll see the fluctuation temprature.

 

It's normal to see a little rise at idle. but if It's jumping half way up, you need to bleed the system. Turn the car on open the two thumb screws near the thermostat. when coolent comes out close them.

 

Are there any signs that my thermostat should be replaced or should i try bleeding the system first and remove air in the system.

 

You have really hot air comming out?? Most camaro's i have ridden in with 160's never really get HOT air, yes it gets warmer, but not hot. What does your engine temp run in Farenhiet? and where do you live? I've flushed everything also....mine doesn't get all that hot, maybe it's just my heatercore.

 

My engine never see's the first quarter mark. Yes I get hot air. This was last night at 18F outside. Indiana.

 

I'm impressed

 

Dont be.. whens the last time you flushed your heater core? In order for me to get this hot of air, I took the inlet hose and outlet hose off the wp, (the ones that go to the heater core) and sprayed with a garden hose sprayer nozzle into the inlet hose. White chunks came out of the heater core, now its pretty warm when the needle on the temp gauge is just touching the bottom mark.

 

Mine blows hot as hell. I always put a jacket on, crank the heater up and roll the windows down at night. Feels like 70 degree weather...ahhh...I love Texas winters.

 

i went ahead and bled out the system. i got it to the point where a steady stream was coming out of the bleed screws. I figured this meant all the air was out of the system. The air in my car was still not showing much heat. I also removed the cap on the radiator barely and fluid was trying to spit out. Does this mean that there may be air still in the system? i also replaced the thermostat. didnt help.

I WANT HEAT!!! haha

 

ttt....anyone?

 

Dude you haven't said anything about hardcore flushing your heatercore...

 

Exactly. Post again after flushing the core.

That's normal. Your fans don't come on until 226° (about halfway on the gauge). The temp rises when sititng in traffic, because there is no air flow across the radiator. There is no choice, but for the engine temp to rise. The fans kick on and the temp goes down. It's the same for any car with electric fans.

 

160* stat and real hot air, even when needle is all the way down when I start the car up, after about 4mins I feel warm air, then needle rises a bit and then its hot air, may its cuz I always used straight water in the car, but i recently put in coolant cuz I'm driving this winter when its sunny for fun since hockey season didn't come this year LOL


PS. when bleeding, if you see steam keep bleeding until you see coolant comming out, I find the best way to bleed is to get the car up to temp and turn it off so the water pump isn't running, give it abou 1 min for the pressure to build up in the coolant system and then start opening up the screws, then the h20 pump is not running and the engine gets hotter when you shut the car off for the enxt 2-3 mins or so before she start cooling down cuz its all still hot but the coolant is not flowing.
