When I rebled the S2000 and a CR-V, the bubbles came in spurts and stopped for a minute or two. Then, a few more, until finally, no bubbles over 5 minutes.

It helps to park the car on an incline with the front of the vehicle higher than the rear.

Good luck!

 

Awesome will definitely try this!

 

Ok for sure will wait longer haha

This may be a dumb question but, I don't need to flush out the coolant in the system and re add new honda coolant correct? I can just buy the same honda coolant I used and open up the radiator cap and fill as needed to check for bubbles?

 

Sometimes it takes a few cool down cycles to purge air. No fancy tools or funnels required. Nose up, crack the bleeder as well. System
is pressurizing when hot?

 

Did you open the bleeder while adding coolant (engine cold and turned off)?

Here's my process which has been bulletproof for me.

Assuming the car is already parked on a flat surface or nose up on an incline.

I turn the key on (engine off) and set the heater knob to full hot and wait til I hear the blend valve completely open.

Shut off the key

Insert coolant bleeding funnel.

Crack open the intake manifold bleeder AND the heater crossover bleeder (rubber cap).

Fill the coolant via the funnel.

Keep filling until a solid stream of coolant comes out of each bleeder and cap/close it when that happens.

Fill the funnel about 1/2 to 3/4 way up with coolant.
Fill the overflow reservoir to its full mark and cap it. Make sure the overflow cap tube is on and is submerged.

Start the car and run the heater at full blast. Monitor the coolant temp gauge to make sure the car never overheats.

Wait for bubbles to stop. Wait for hot ass heat in the cabin.

Turn off the engine, remove the funnel and cap the radiator

Go for a short drive. Make sure the heater is blowing hot and the car isn't overheating.

Park overnight.
Wait for it to cool.

Check the reservoir level and top off as needed.
Check the radiator level and top off as needed.

Confirm hot heat and proper coolant temp on your gauge on the next drive.

 

And by hot ass heat, he means hot ass heat. Put the back of your knuckles about an inch or so in front of the vent. It should start getting uncomfortable to hold them there when it reaches the right temp. Then you have hott ass heat A lot feel good warm air and think it is good only to find out after driving there is still air in the system.



It should not take any driving around or repeating if you bleed it thoroughly the first time. I have never had to repeat the process once I did it all the way through.

 

Not required, but the Lisle type funnels make things sooooo much easier.

 

Everyone should own one of these. Not that expensive and frigging awesome!

 

Yep I pretty much start off with the Billman method to get the bulk of the initial air out but put the funnel on for the last part and just let it go. does a great job. Plus, it is a great funnel for filling coolant in general.

 

I think it's a great tool, less mess. It's better than having the radiator burping coolant all over the front of a running motor.
