I've replaced the water temp sensor, swapped the relays with other ones and checked fuses. The fans will kick on for the a/c. I just finished doing the head gaskets, seems like the fan problem caused the head problem. I also found that there's a clanking noise that's coming from the radiator, I'm guessing that's caused by the heat. Any help would be great.
 
Do you have access/rent a scan tool? Check the fuse box where the relays plug into to see if the connections are broken. Check all harness connections and wires for a break. If nothing found it could be the ECM.
 
You might hear a ticking sound from heat, but clanking? Is this while the car is running? Almost sounds like a no-flow situation. What's temperature doing?
 
I swaped the relays around before hand to see if one was bad, the temp is going up to around 200-210, and the clanking and banging is while its running when it gets close to 200. I'm checking the connections everywhere right now.
