Test Stock Clutch Fan?

sniper_101 · Nov 4, 2012

Any positive way to test this thing?

Feels like it's always engaged and stretching out my warm up times and keeping my oil from getting up to temp (150-160*EOT max after 30+ min of highway).

Thanks

i could hear mine pulling air in 1rst gear when it locked up...i pulled the blades off and ran it a couple weeks without a fan before i put a new one back on...corse it was winter time then..

Engine off, KEYS IN YOUR POCKET, can you turn the fan blade?

Mine seems to turn on all the time too. These things have goofy clutch operations.

I only hear mine on really hot days. There is know doubting when it is working. Sounds like somebody parked a 747 under the hood.

It will turn, but drags very heavy.

If I can get this f'in clutch to unthread from the pump shaft I'll try running it without.

If its dragging, it's likely working.

What's the ECT doin when the EOT is low?

Wish the clutch for the fan was electric . . . would make life so much better.

Within 10-15*. Doesn't seem hot enough to open the thermostat, but it could be partially open.

Think I'm gonna order a 203* T-stat and new housing . . .

*Edit - Ordered.

I did replace the t-stat when I did the water pump in the spring, but I replaced it with a Napa replacement unit. I think it was only 192 or 195, so I'm hoping I'll see a difference,

I was going to suggest to start with a thermostat.

My fan clutch is gawwwwwwwwn.....just discovered it when I started pulling my motor last Friday night.

I wonxered why it spun so easily.

203* Thermostat from DieselSite (and their Billet Housing), made a huge difference. Oil temps at idle/city speeds were 145-150, 150-160 on the highway. Now it's about 165-180 idle/city, and 185-195 on the highway. Perfect! Still have the grille blocked off to help warm up faster though.

Just wanted to put this info out there for anyone else in the North that has trouble in the winter. For the $35-90, this was cheap help. Now I hope I see my winter mileage back up a bit!
