22RE fan runs constantly
This is on a 90 4x4, the fan 'roar' never stops, meaning the fan doesn't turn off; engine isn't overheating, thermostat is brand new and working properly. Is this pointing towards fan clutch replacement? When cold, I can turn the fan by hand with mild resistance. My net searching on this turns up a lot on the opposite problem, eg. fan never runs & engine overheats, but I haven't found much on this issue.
Thanks in advance, any advice appreciated.

Mine is constantly spinning too. What's the best way to test a fan clutch? When it's cool or hot?

The manual I have makes it look like you need to take out the radiator. I guess removing the shroud will work, but that still doesn't give me much room to work. I'll take a look at it tomorrow if that's the case.

DupermanDave- find a 10mm boxed end wrench, long or stubby depends on your dexterity, a ratcheting wrench may be better, and you should be fine. You'll notice that the fan doesn't have blades evenly spaced so just rotate the fan so that the most widely spaced blades are closest to the nut you're loosening and that should give you enough clearance to get your wrench, and your hand, in there.
But you do have to get the shroud off so...
I'm going to add that there may be 6 bolts to get the shroud off- the 4 that hold the shroud to the radiator and two down below the fan that holds a small section of the shroud on to the main shroud that when removed allow the shroud to easily lift up without interference from the fan.

Thanks for the rebuild link.
Yeah, pay attention to this. I wish I had noticed it when I put in a new fan clutch many years ago while working around the loosened shroud. That bottom part that otherwise would prevent removal around the fan comes off.
My 86 has clips that hold the piece on. Clips, bolts, whatever -- it comes off.

Thank Toyota engineers for thinking ahead. Blame the manual writers for not mentioning this feature. The manuals I've seen say nothing about that part being removable, and not looking closely I assumed the shroud was one piece.
Removing and installing a fan clutch with the shroud dangling in the way wasn't fun. If you know to take the bottom part off and yank the shroud out, piece of cake.
