That's normal. It takes a while for the fluid inside the clutch to
warm up and allow the fan to slip. Let the engine warm up a bit and
then try again.

Fan Clutch malfunctioning?
 

Hi: ... '91 Jeep Cherokee, 4.0L HO motor.

It's about ten degrees outside, and when I start the motor cold, the fan
spins like its bolted straight on. Faster engine speed = faster fan speed.
The air coming off the fan blows my hand back.

With the motor off and cold, I can turn the fan, but there is plenty of
resistance, it's *definitely* not spinning freely.

Is there any way to "fix" a fan clutch? Maybe it just needs cleaning or
something? Anybody messed with this before dropping $70 on a new clutch?

Is there a good kit for conversion to electric fan? What are the pros/cons
of electric fan vs. mechanical clutch?

Thanks.

I had a similar problem with my '98 XJ... the clutch was bad and I
replaced it with a HD aftermarket one... the clutch was engaged all the
time. Regardless of temp and how long the engine was running.

Turned out to just be a bad clutch, even though it was fresh out the
box. A replacement one went in and now its fine. It will run for the
first minute or two then operate normally.

The original was dead, wouldn't engaged period and I could tell in
traffic as the temp would rise a little faster until the electric fan
kicked in. Never overheated though, even in 113 heat out in Palm
Springs...
