Fan clutch question

Question.

If the engine is hot and I turn off the engine, how tight or loose shou,d the fan be? I'm trying to figure out the fan clutch and I can't tell if it ends replacing.

Thanks

Usually I would warm up the engine tooperatingtemp and then use a soft stick or something to tryand slow down the fan with the engine running. If you can stop it the clutch is bad, because warmed up the fan should lockup and turn at the pulley speed

I'll try that. I did notice that the fan became more stiff as the engine cooled down vs warmed up.

Thx

It needs to be a lot more than warmed up. The fan needs to get quite hot. It turns "On" and "Off". It is not progressive. You can hear it lock, if you listen closely.

So if I'm idling in my driveway and the temp gauge is practically pegged, shouldnt the fan clutch be "locked" if I turn off tha truck and check immediately?

So the fan clutch is shot and I think it's the original on the truck. I will be replacing this weekend before the real heat arrives.

I'm going with an Imperial Fan clutch that was 40 bucks at advance auto based on a discoweb post a few years back. I looked at possibly an electric as well. I must say that my truck does a pretty good job cooling but it will of course cool a lot better once than fan is in fact working as expected. I also am going to do a valve cover gasket job this weekend as I noticed a bit of oil smoke coming up through one of the cover bolts.

I'll warn you that I tried the imperial and it was too strong/load and never kicked off (and you have to enlarge the fan bolt holes to use it. Likewise on the loudness with the non-genuine (britpart?) ones. The only ones that don't drive me nuts, but still cool properly are the genuine ones - in two different trucks. YMMV

I prefer electric. Cleans up the engine bay and is very efficient. If wired with a good controller can cost $$ but the flexibility is nice.

Im using a Zirgo 16in fan

http://www.summitracing.com/parts/HFM-ZFB16S/?rtype=10

Spal Controller

http://www.spalusa.com/store/Main.aspx?html=pwmv3

and the spal optional temp sensor and a ebay 32mm hose adapter for the temp sensor.


This setup is great, the Zirgo fan just perfectly sits against the rad surround, witgh some nylon style fan mounts (thru core) it was tight and immobile. The spal controller is water resistant and internally relayed. You can use it with AC and override on or off switches. Fully programmable for temp on/off or cycling.


Downsides are:

you need a heavy gauge fused circuit and it relies on electronics instead of mechanical action

I've done electric. In the end I consider it one more thing to fail, and if everything is working as it should, the stock setup should be sufficient.

Got pix of your setup?
