I just replaced my optispark and now that everything is back together it is overheating. Also the fans do not come on at all. Do I need to bleed the cooling system? If so how do I do it? Thanks

 

you definatley need to bleed the coolant system if you havent with the engine running loosen the two brass screws by the waterpump (see pic) keep them loose untill coolant flows out then tighten. as far as the fans i would check all connections and relays im not too familiar with the fans. hears a pic of the two screws you must loosen one is on a big hose going directly to the waterpump and the other is on a smaller hose next to it

check the fan relays in the fuse box next to the intake
