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?
