I need help bad my car holds a idle at 2k nd it bounces I'm sure its air in the coolant system because I did the swap and the fan hasn't turned on yet and the thermostat hasn't opened to receive coolant but I'm not sure how long I should leave the car on so it can kick in. Also I'm using a singlecam cx ecu nd its a jdm b20 anyone can help me how to bleed the coolant

you need to get a new ECU as the CX ecu is made for 180cc injectors and the B20 has 240cc. Do you have any check engine lights?

 

great video. i did it the same way

 

yeah you don't necessarily need that funnel kit he has (although it works great) you can just use a regular funnel

 

I do have check engine gona run the codes tomoro. Also I'm gettin a ls ecu hopefully dat throws 240cc because I don't know. I still don't understand the video because in my car the fan won't come on and tnhe thermostant will not open to let coolant flow

 

fixed the coolant issue and i changed the cx ecu put a ls one but it makes my car turn off after turning it on the cx one at least leaves it on

 

You can squeeze the upper rad hose with the car off and it will usually suck more coolant down so you can add more. Then just let it idle with the rad cap off and top off whenever theres room.
