New Cylinder HEad: Engine Coolant Air Bleed Plug - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

ztsmith86 · 02-01-2012, 07:58 AM

When installing new cylinder heads it is recommended you install new engine coolant air bleed plugs into the rear coolant passage of the cylinder heads. Has anyone done this or have experience? I'm looking for a good thread or maybe some sort of write-up. Also if someone is willing to point me in the right direction for buying the parts that would be appreciated too. Thanks!

Is it even necessary to install new ones when replacing the heads? Can you just swap the plugs from the stock heads into your new heads? Thanks

I bought a set of ported ls3 heads. Casting number 0821

Just swap your stock stuff over.

You ever seen the stock ones? I wouldn't even know how to get them out. I had to drill them on the ls7 heads I used on my car.

Hmmm. So I'm still confused people seem to be saying conflicting statements here.

I don't think you are talking about the same thing we are. You just take a 10mm socket (or wrench), remove the four bolts holding the two rear plugs/front cross over and reinstall on your new motor.

See above.

I'm saying my heads didn't have the block offs bolted in. There were actual plugs pushed down into the heads. That I had to drill out.
