Hi. Does anybody knows if Evo 9 got some kind of coolant air bleeder valve?

 

It does not.
I would recommend running one of the big and tall funnels that clips into the radiator cap position.
Run it up to full temp, burp the bubbles with a little revs (3000rpm or so) then allow it to cool.
Once it's cold, then remove the funnel and put the cap on.

 

Thanks will do. I found a special set in my local shop.

 

We don't have a bleeder, and these car bleed very easily on their own with that bleeder funnel you found there. Just turn the heater on and let it warm up.

 

hmm i thought that air bubbles will just come out when it reaches radiator cap pressure and gets replaced by coolant from the reservoir

 

Yes, but then the system is low. That funnel you coolant in it, so as air comes out, coolant goes into the system

 

I guess thats the professional method. I just run the engine and keep filling until it overflows and flowing thru the upper hose. I put extra on the reservoir. I should probably turn the heater on next time, it just never crossed my mind lol

 

For <$20 or so for those funnel kits, it's just nice to not spill lol

 

true but I also eject all the coolant thru the lower radiator hose

 

Btw what should be the correct level of coolant? I guess after completing this process my radiator will be 100% full but what about this expansion tank? To be honest I never saw any fluid in there

 

It's an overflow tank, not an expansion tank like in a pressurized coolant system. If there's too much coolant, your overflow tube will dump coolant.

The jiggle pin on the thermostat helps the system bleed.

 

With the radiator properly full, I usually just fill the expansion tank with a couple inches of coolant so it's not empty. Gives more expansion room.

 

I recently returned my OEM tools kit because it was leaking out of the cap. Which kit did you get? I would like to find one that is truly leak free. I wonder if it’s because my radiator is an old CBRD one so the neck/cap isn’t exactly OEM.
