did a dohc zc swap in my friends 90 crx, everything is complete and there are no codes running, it just overheats after running for a while ... the car runs perfect and idles perfect just it over heats for no reason, there was one sensor on the d16a intake manifold that there isnt on the zc manifold. i think its the iac valve, any suggestions would help thanks

 

Have you confirmed that the thermostat is working, or that the coolent is passing through the system correctly? Is the fan coming on? We need more detail so that we can help.
