Electric Cooling fan?
So just put in a new radiator, hoses and thermostat. And after letting it hit 190, confirmed with a laser thermometer, my electric fan didn't kick on. I turned on the ac and defrost and nothing. What do I test and how. It's a 88 XJ 4.0 auto with the factory tow package, two radiator coolers.

You have one mechanical fan and one electrical fan?
If so the electric fan turn on with the a/c and or when the temps hit 218. (at least for my 1999) |
Test the electric fan and put power to it. If it works plug it back on and run the jeep for 30 minutes and see if kicks on. You can also make the fan come on constantly with your ignition. You can also put a toggle switch for it and control when it comes on. Just make sure you place the switch somewhere above your knees.

Anyone know why my electric fan clicks on and off at very regular 10 second intervals when idling? It got so annoying I disconnected it, but I would like to get to the bottom of the problem.

What cooling system maintenance has been done? Which list is shorter, what has been replaced or what hasn't been replaced?
|
So far I have replaced the radiator, all hoses, and the thermostat. It is running great and isn't overheating at all, but I have to take it on a 8 hour drive in a couple of weeks to southern Oregon and I don't want to have any issues on the drive. I didn't get a chance to hook direct power to the fan yet. But when I turn on the ac it blows cold and the fan doesn't kick on, so I'm pretty sure that the fan and or relay is toast. I can get a used fan for 20 bucks so I'm going to go ahead and get it and see if it works. If not I will get the regulator.
