b16a in a 91 integra, the fans worked when i had the b18a in and now with the b16 the fans won't come on so the it overheats when its idle. How do you bleed the b16, I'm used to bleeding the coolant on the b18a with the bleeder bolt, but i have no clue on how to with the b16a is there some type of bleeder bolt?. The fans are plugged in and everything. Replaced all parts for cooling system also: water pump,timing belt, thermostat,hoses,radiator. So, can someone help me?

Run the engine with the hood open and the radiator cap off. This will bleed out any air in the system. As far as your fan not coming on, make sure its wired correctly into the harness. If it worked before, it should work now. Try putting voltage from the relay to the fan wire and see if it comes on. If it does, than its a switch/relay issue. If it doesnt, than it could be the same problem PLUS a bad fan clutch or motor.
 
Could be the temperature switch or coolant temp. sensor. If that doesn't solve your problem just wire the fans direct and to the ignition switch which fans will always be on once ignition key switch is on. To make sure that the fans are working run 2 wires positive and negative to the battery just to make sure that the fans aren't seized up. Good luck on that.
 
I'm going to try to take my switches from my b18a and see if they work, but the b16a came out of my other car and the fans and everything worked fine! so i don't understand it, and i don't want to wire the fans to always be on because that is really annoying to me and is a tacky way of doing it
 
You can wire the fans to an rpm activated switch, that way it will only come on when your rpm is at idle. Or you can just do what everyone else does and run a switch for the fan so you can turn it on whenever you feel the need to.
 
i want it to run as stock as possible, no hacked up wiring for fans to come on and such, i don't want to deal with pressing a button for it to come on. I'll get to work on it asap
 
Than verify the problem, fix it and make sure it is working properly. What else can I tell you? Get the wiring diagrams and schematics from a local shop, offer than 10 bucks for the printout if they are jerkoffs and begin routing all the wiring.
 
i fixed it, fans are working, thanks everyone;) i just need to fix the vtec now getting a code 22 and 23
 
I really have no idea, they finally came on after i bled the system and i re plugged them in, but i can't figure out this code 22 and my vtec wire is grounded and is plugged in the solenoid!!! so annoying
 
i tried 3 different ground places and it was clean and snug and i still keep getting a code 22
