Radiator fan not working.

make sure the spade terminals on the sensor aren't corroded; good idea to wire brush them when you replace the wire ends

I had a problem with my fan, and it ended up being one of the plastic block wire connectors on the way to the fan. It can be jiggled into a place where it makes a good connection and works, but I'd like to replace the connector. Any idea where these can be bought?

any auto supply or hardware store should have connectors, I think even the grocery stores have them now!

"if the fan came on with the sensor bridged, then the problem is either a faulty sensor or connections, or a thermostat that isn't allowing hot water to the radiator. The next step is to run the car until it gets to operating temp and feel the bottom of the radiator. If it's not hot, then the thermostat isn't opening. The t-stat could be faulty or there could be air in the system. Have you had to add coolant to the cooling system? If so, there's probably air trapped at the t-stat"

The bottom of the radiator is hot. What's the next step?

Thanks,

replace the sensor. You'll have to drain the cooling system, then bleed the air after refilling with the new sensor in place.
If you had a volt/ohmeter you could test the sensor for continuity once the coolant reached 195

Any suggestion on where I should purchase the sensor? After draining the coolant, do I just unscrew the bad sensor and replace it with the new?

How about a quick lesson on draining, replacing and bleeding the coolant in the radiator.

Thanks,
