I used a brake bleeder to pull it to the opening, after I realized it might never come on its own.

 

BillMan, Thanks for all your help by the way. I have another question thought about the hg. If the HG was blown wouldn't I get a misfire code on a cylinder or random misfire something in that sense or not always?

 

ap1v1 dash (3 bars for op temp)
ap1v2 dash (3 bars for op temp)
ap2v1 dash 04-05
ap2v2 dash 06-07
ap2v3 dash 08-09 (8 bars out of 16 for op temp)
CR dash

I confirmed on my ap2v3. My eyes were going crazy trying to count those small increments.

Carry on!

 

My 05 AP2 has 8 bars for normal operating temp.

Will be doing this bleed in a few weeks (probably March).

 

I typically leave the fan speed on low at the beginning until the engine warms up a bit. Helps speed up the heating process.

 

As another option that I've used is the Lisle Spill Free Funnel to "burp" the cooling system; an example can be seen at this link: http://www.amazon.com/Lisle-24610-Sp...coolant+funnel

Using this funnel was the only way that I could think of to burp the coolant system of the S2000 with the radiator cap off and engine running, without spilling coolant all over the place. I just kept the funnel half filled with the engine running. As air escapes the system the liquid level in the funnel will gradually drop. Occasionally bliping the throttle helps. As Billman already said, once hot air is consistently felt from the cooling vents the cooling system of your car is mostly free of trapped air.

 

06+ (including CR) are all 8 bars at normal operating temp. The 08/09 cluster's bars are a little thinner than the 04-07 bars, but they have the same number at normal operating temp.

 

I have this same funnel and it's a huge time saver. I've used it to burp other cars that's much harder to bleed than the S2000. It takes a lot of guesswork out of the equation.

 

With this method, is there anything else you need to do to get air out of the system? If you just run the car with the funnel on, and occasionally blip the throttle, will it eventually get all the air out of the system?

 

You might want to squeeze on the hoses also to help get all the air out.
