Any update on the fan issue?

Looking for the root cause of the overheating?

tim07 · 05-24-2022, 06:13 PM

I called the engineer at Horton, he thinks the guard dog will solve the issue. It was about half the price of the static fan option. I'm attempting to install myself. Only thing is I need a adapter harness because my connectors are oval instead of square. So, the harness is on its way. I'll let you know if it's successful.

Guard Dog may solve the overheating problem, if it is the electronics causing the problem. It will not help, if the fan clutch has gone bad.

This reminds me of a political saying: "Let's replace what worked, with something that sounds good".

We had 1000s of miles to finish or trip and was very, very glad that we had a new fan clutch. The Temp always remained steady a about 189.

A Source Engineering direct drive fan may have even been better. Some reviews had very good things to say about it. Source Engineering told me, that they needed to remove the radiator and inter-cooler to install the fixed fan. That's a big job. It would be much better, if it could be done from below.

Again, near 40,000 miles, I would do something about it, before making a big trip.

This work I'm doing now, (guard dog), follows diesel mechanics cleaning radiators, changing clutch fan, new thermostat. The guard dog is something I can do myself, and it's half the cost of the static fan, not to mention the labor involved by the mechanics to change the clutch fan over to fixed.

I’m planing on replacing the Horton clutch fan on my 2009 Winnebago 34Y journey (cummins 6.7 engine) with the Source Engineering direct drive fan. Does anyone know the part number for the spacer block that is needed to install the S/E direct drive fan.
Also where this part can be purchased.

Have you asked the (knowledgeable) guys at Source Engineering?

Proper fan spacing in the shroud SHOULD come up as a question 100% of the time.

When we did our son's, or rather gathered the parts for the mechanic, I bought all parts from Superior Turbo and Injection out of Detroit. They knew which spacer to use and milled the exact one. Fan = $160.00, spacer = $295.00. S&H = $ 208.00.

I just replaced the fan clutch on my 2008 cummins ISB 6.7 with a direct drive fan and I got everything from Superior Turbo. Cost about $600 for fan and spacer and I did the work myself.

Yes, I talked with Jim @ Source Engineering. They have the fan blade in stock, but the spacer block has to be purchased from alternative source.
He recommended asking on the iRV2 forum to get the part number as other rv owners with the same engine have done the same conversation.
I was hoping that this would be a stock part and I would not have to fabricate the spacer block.

Thanks for the info, I will contact Superior Turbo.
I was planning on repairing the fan myself, can you please give me some idea as to what procedure you did to replace the fan.
Did you pull the the radiator or where you able to install another way.

Hi - when I replaced the failing fan clutch in our 08 Winnebago Journey with 6.7L ISB 2007 EPA engine, this is the spacer that I used:

Cummins fan spacer 3910130 Case NH 76605660 OEM

The 'old' spacer with the clutch was 1.5" deep, and the one which gave the proper depth with the Source Engineering fan was 2" deep. It was a perfect fit with the Source Engineering fan which I purchased directly from Source Engineering.
The depth has to be such that the fan itself is centered within the fan cowl/housing so that it is half in/half out, and not all the way on one side or the other of the housing.
Depending on the depth of the fan itself and the specific install, the depth may vary, so the part depth may also need to be varied.
This makes it difficult to tell you precisely which part to order, but I am happy to share what worked for us (part number above). If nothing else, it at least gives you a starting point with part numbers, photo, and precisely what the part is called.
Best of luck.
John

Superior turbo I believe made the spacer for mine. They needed the part number for the fan clutch and then I had a spacer between the pulley and the clutch fan that I had to give them the measurement for. I tried very hard to replace without removing the radiator but that just did not happen. I was able to remove the fan clutch without taking the radiator out but there was just not enough room to take the fan blade out. The spacer was $175.00. I wish I had just taken the radiator out to start with

Remove RAD and CAC from rear of coach.
Remove rubber shroud from around rad.
Most of the work can be done from rear of coach
Test and clean rad and at rad shop.
Replace and check rad hoses.
Replace stat
Replace hose clamps with T bolt clamps. (had one rust and create leak)
When you remove metal fan shroud, look to see which way nuts and bolts are installed.
Take pictures!!!!!!!!!
One person can remove rad and CAC. Just walk down a couple of planks to ground.Not that heavy. Two people to re install.
Bumper comes apart in the middle to slide out.
Contact Larry at Superior Turbo, he has everything you need to complete this project.
The High Performance Fan
Spacer for fan( if not replacing Horton Fan Clutch)
All stats for fans, CFM,HP to drive fan.
Good luck

Have laid out a step by step process for this project. Search my name
Good luck

Do you have the part number for that multi blade fan, and or hub adapter?
