Thanks for the pix. I appreciate it.

I see the "heater hose" connection going to the bleeder bolt on the waterneck. That's neat. A lot of air comes out of that bolt when I bleed.

So you can just plumb the bleeder bolt line straight to the heater core and then back to the expansion tank. That makes sense. Hot coolant is coming out of the waterneck and all of the air would get bled from the heater core.

That looks awesome. I'm ordering it today.

Thanks for the response.
