What e clutch are you using? Worth installing?

Horton 450.....for me, yes. I have total control over fan and it's also on a temp switch. Love it. A few of us here did the swap. Truck warms up quicker, better MPGs. The downfall is finding one at a good price.

Can someone point me in the right direction on the 6leaker fan swap data?

You can simply bolt the 6.0 fan onto the obs fan clutch.

Does it pull more air, is it quieter? What is the plus?

Magnum PD · Dec 26, 2016

Pulls more air. More and bigger fins.

Billy, do you still have the Dodge/Cummins lower radiator hose on the International pump?

gnxtc2 · Dec 27, 2016

Yes

Do OBS have cooling issues? I have went up Sunset Point on I17 towing 10-11k with outside temp being 100+ and it never got past the "R" in NORMAL

I have the IH water pump and agree the orings on the valve need to be changed out before you put the pump on. I used metric ones for a slightly tighter fit. For the lower hose, the 92 7.3 IDI lower hose fits like factory except the lower connection is slightly larger than the neck on the radiator (so is the Dodge one) Dayco and Gates make hose adapter sleeves, with one of them it fits and looks factory. I have the 6.0 fan, an improvement. Want to put on my EC 450 cluctch but don't want to go backwards on the fan so I'm looking for a plastic fan with the right offset to fit the EC450 with the Fluidamper.

Would you know the size of the metric o-ring?

I documented the whole thing but don't have access to it at the moment. I have a lot of good things I've documented over the years but never took the time to post pictures.

For you Billy, I will go dig it up soon.

Thanks....

I ran into the same thing concerning the oring. I tried the -205 size. It works but it just does not feel right. I went to my hydraulic shop and they gave me a few metric orings to try. They gave generic Buna rubber ones as thats all they had. They gave me 9mmx4mm and 11mmx4mm. They smaller one is almost the same as the -205.

I already have the IH water pump on my truck and was planning on upgrading to the 6.0 fan when I change out my harmonic balancer to a Fluidampr but reading about this Horton EC450 electric fan clutch definitely has me swayed to go that route now. Adding this to one of my 2017 goals for my truck.

Did you ever find the info on the O-ring swap?

Like to read it,
I will be doing the pump swap soon...
Thanks

Replacing the o ring on the coolant filter shut off valve with an 11mm x 4mm solved the problem. Tightened up the valve. IIRC the metric oring was about .020 bigger on the cross section and fit like it was engineered that way.

I have the lower hose for a 91 F350 with 7.3 IDI fits like stock except need to use an adapter bushing (rubber sleeve) because the PSD neck is smaller. It literally fits like stock with the T-444E water pump except for the bushing.

I have Dayco part numbers at home but never any time when I'm home LOL.
