Searched.. coudlnt find it. I want to bleed my system.. just installed civic rad and a slim fan. I take the cap off and let it run at normal temp (1/2 way on the dash) for 15 mins or so... but where is the bleeder valve???
Thanks for the help... gotta get my lude fixed.. im selling her and all her parts : (

 

On top of your thermostat housing.

 

Here you go!



It's behind your head, under your VTEC solenoid, near the EGR valve. There's a coolant hose that runs to it. On top of the thermostat housing is a nipple that you need to remove to bleed the rest of the system. Let me know if you can't find it.

 

yeah its 12mm youll see it...fill coolant, open bleeder till no bubbles, idle engine till op temp with heat on full blast, refill rad

 

wait so do I let this bleeder valve open while the engine idles? or just when filling?

 

Just during the filling. Once coolant comes out, its bled, tighten the screw.

Then after you have run it for a bit, and let it cool down, check the radiator, and top it off there as needed.

Leave it open when it's at idle. And continue filling it until it all the bubbles are out, and there's a solid stream of coolant coming out.
