Default Fan Clutch on FC

Hi All,

I am doing a little work on the radiator hoses and I though that there was only a horton fan clutch but on mine there is only electric wires and no air line going to the clutch. Could this be a different type of clutch (eletrical) all I was going by was the photos that John has on his PBase site.

Thanks Denny

Talking Maybe it"s an 80 Thing.

Denny,
I have an electric fan clutch on my 1980 also.

Maybe you are right about the 80's thing

Mine was also very corroded that maybe why it was over heating. Can you hear the fan clutch come on when driving?

Thanks Denny

No doubt about it. Ground one wire, 12v to the other, fan clutch should lock. The rubber torque strap needs to be functional. Very important.

Definitely can hear the fan kick on while driving. Mine actually comes on a bit higher than I think it should so I normally use my bypass switch to bring it on a little sooner. Temp kicks it in about 200 degrees by my guage, I try to get it on around 190. Have also noticed that by kicking it on before starting a climb it does not heat up to the auto kick on point.

Denny,

The Horton fan as you saw on my 'Bird, I'm sure could have been ordered from the factory when the coach was built, but some of those 'Birds that have them were changed later. The Horton while very efficient is not a cheap upgrade, so if the electric that you may have can be repaired that would save you some $$$$

If you have 195 degree thermostats then the fan should kick on at 205 degrees. In fact if the coolant is operating correctly and your radiator is alright, the fan should not kick on unless you are either idling along time in traffic, or pulling a hill.

On my 1982 FC35 with a horton fan, it only kicked on once all the way to Florida unless I manually kicked it on myself when pulling a long hill off the interstate.

A little hold up on my trip south, discovered failed bearing on magnet winding, reduced diameter on shaft a little, have to build up worn area on circular welding plate and turn back to size. I didn't watch the condition of those bearings close enough, real glad I'm fixing it in the shop and not out on the road.
Them bearings look like they should be changed @ 50k miles to be safe, now that they have my attention.
