I'm new, so hello to all. Right to the meat. I've checked or replaced thermostat sensors. Thermostat, fuses and relay's. And engine fan does not come on. Fans work, but only if I jumper the relay n/o. Will not click on it's own. Someone please help, before I go mad..

 

Have you checked for a signal to kick the relay on? If you are getting the signal you probably need to replace the relay.

 

I'm not getting the signal. And I replaced the relay, checked all fuses. Even jumped the relay and still overheats. No water in the oil. But still not cooling

 

Turn the ignition to on without starting the car and disconnect the connector for the fan switch at the thermostat housing and stick a paperclip in there to jump it. See if the fan comes on. If so then the fan switch is bad. Get a new one directly from Honda.

 

Done that and no fan coming on

 

The only thing left upstream in the line besides a possible open in the wiring is the fan timer.
