i was doing research on an erratic idle, cleaned my iac valve 3 times, got a new iac valve, and now im seeing where i should have burped the coolant.

my overflow is always empty i check the radiator and its always full and my guage is always where it should be. tomorrow ill pick up some honda coolant and see whats up.

what all will i need and wheres the bleeder screw?

 

What honda?
What motor?
What year?

 

Like above need year and model. 96 and newer no bleeder screws.

Overflow always empty, that is not a good sign.

In the stickies there the bleed procedure, do that refill the radiator and the overfill to right level depending on hot or cold.

I would get a new oem radiator cap, I am wondering if the system is not be pressurized right.

 

its an em1

 

i also didnt mention iac valve fixed my problem with the codes, and the idle is almost where i want it. its a little high when it starts up and doesnt idle back down quickly like it used to.
