I believe I have an electromagnetic clutch according to the parts listing.

Yes, it is overheating and boiling over at idle.

I see two fans, one attached to the engine block and one in front of the radiator; I believe this one is associated with the transmission. Is it possible that neither fan sys is working?

I'm guessing it could be the temp switch, fan clutch or wiring. The radiator, fans, and fan shrouds appear to be in good condition.

How should I go about troubleshooting the fan system?

My A/C system is not working either, which is fine, but will it have any effect on the engine cooling system?

Thanks for your help
