View Full Version : Did I do something wrong?

I bled the system like everyone said to do, filled it at the crossover tube, and my heat still sucks. Did I miss anything? Could it be the t-stat?

Did you have your car on an incline? Did you put your heater on high to move air out of your heater core?

Try those...

You may have to burp the system a few times to get all of the air out. If you never replaced the t-stat it wouldn't be a bad idea to just go ahead and do it.

Everyone says to do this, but I honestly cant see how it helps get air out of the system. :depress:

It just worked for me...That's why I mention it...

Nope Randy, it was on a level surface. After I added coolant though, I turned the car on, and I had the heat on full blast and it still did what it's been doing.

When I did mine, it was on a slight incline too. Oh, and I did it with the engine off and cooled.
One quick question: The blower is working, right?

Mine was very cold, it was sitting for a week without being started. Yep, the blower is working as it should.

Jarod, get a funnel with a neck that matches the fill hole. You may have to cut one. Stuff the funnel in the hole so it seals and fill the funnel. Let the engine idle 'till the thermo opens. The bubbles will float in the funnel and the coolant will replace it. Run it 'til no bubbles. 10-15 min?

With this technique I have never had to 'burp' the system nor had heat issues.

^^^That's what I do ^^^ While on an incline...

Thanks Rich...Got that from you!

The incline is a waste of effort with the 'funnel' technique. We are making the level in the funnel the highest point in the system. Gravity does the rest.

No effort on my part...My driveway is inclined...

I'm thinking that having the engine at an angle...helps air move toward the front (funnel) and not get caught in any nook and cranny along its way...

Doesn't hurt...

Assisted Gravity. Doesn't hurt. :beer:

I agree. Move the temp to max to fully open the system.

That's what I did when I started the car after.

Not really necessary since water circulates through the heater core all the time.....no valves in the system!!:shake:

To be sure all air is out carefully remove the upper heater core hose a little and see what comes out....air (bad)......coolant (good)!! If air just let it out until coolant flows!!:beer:

Top up crossover and reservoir and you should be OK!!:D

If the burping doesn't fix it then it's possibly the blend door, or the HVAC device. See the thread "No heat fix" back in 12-27-2006. In that thread is a procedure that checks and resets the electronics of the HVAC by pressing some buttons. Try it out. FWIW

Most modern cars, especially those with A/C, do not have a coolant flow valve in the heater system. Coolant flows through the heater core at all times. Outlet air temperature is determined by the blend door, which opens or closes to allow outside air to mix with the heated (or cooled) air blown across the core (or the evaporator).
