I just replace a new AC compressor and AC condenser. Everything works properly with no AC leak. My concern is that after I install the new parts, the radiator fan automatically comes on right when I start the motor in cold temperature. I am not sure if that is normal or if I have to of the connectors from the AC condenser backwards (see picture). I always think that fan should automatically engage when the motor reaches to its high temperature and when the thermostats open. Another concern as well. I am not sure where this part connects to (see picture)? Is that suppose to be attached to a radiator or AC condenser and if so which location of the radiator or AC condenser?

I do not think the connections are backwards on the condenser because I do not think the thread size is the same. The fan it suppose to run with the AC on so that is normal even when cold. If the fan runs without the AC on that is another issue. It is hard to tell what you are talking about with the missing parts or? Can you please take more pictures of the issue and explain a little more?
