Spider 2000. Have all the wiring connected, heated up the Radiator Temp Sending Switch before install and it kicked on the cooling fan. After it cooled down, I put the temp sending switch in the radiator and it will not turn the cooling fan on, still over heats at idle. What the hell is wrong? This is frustrating me.

blocked radiator?

Thanks Arc, but all mechanical aspects of the system are working, including the fan and temp switch, this is an electrical issue. I believe the relay is my problem.

Generally speaking almost all of the overheating problems with the spider/2000 stem from air in the cooling sustem. For some reason many people have problems bleeding the cooling sytem properly.
