'89 R3500 Crew Cab 2wd to 4wd conversion & beyond
- Thread starter mrk5

Started out with 2wd TBI350 with SM465 to current 4wd with 454, 700r4, NP241
Or a rheostat on the temp wire so you can turn the gauge to whatever you want.
I did look that over and it fits nicely. There's maybe an 1/8" gap between shroud and radiator. I did see one notch on the passenger side of the shroud that must clear something on the 6.2. Was thinking I could cover that up, not that it's very big.
Got that already....and a 180* t-stat

And here I drive the C10 home with AC running, 91° out and the fans don't come on until 12 minutes into the drive engine temp never gets above 190°. All it has is is a big block radiator and Windstar fans.
Running an SBC and a 1.5 ton lighter probably helps.

You’re sure your crew cab radiator isn’t blocked somewhere?
Only thing in front of it is a trans cooler. I'd love to have an an condenser in front of it but I don't.
Is the gauge actually reading accurate? I'll be honest I skipped back only a few pages.
I'll be that guy though. 3800CFM with dual row 1" tubes. Its a drop in solution once you cut whatever is in the way. You'll stop hearing the insane fan noise after a few trail rides.

It is a new radiator about 2 years ago. Had a whole fiasco getting one; took 3 tries before I got one undamaged in shipping.
Before the mechanical fan I had an 18" Lincoln fan with a 17" Volvo fan. They totally covered the 19"x35" core with a little fan hanging over on 1 side. It was great on the trail, but not so good towing.Is the gauge actually reading accurate? I'll be honest I skipped back only a few pages.

I've mentioned before, it probably isn't easy to find a balance between the 2 uses.
It's not the fans were looking at here. Mech flows more than electrical. But if your rad just can't keep up then it can't keep up.
I don't think it's the radiator, it's air flow. I have to block the radiator in the winter so it will warm up at all.
So get really creative and cut you radiator support. You hole is for a gas motor and you radiator is a diesel like 6 inches are not seeing any air.
If you Google adjusting a thermal fan clutch, there is a lot of discussion about it. A few videos was well. I am not going to link anything here, because there is lots of discussion to sort through in some places.
Make a mark where you start and see what adjustments do.
And it's just labor to try it!!

That's not a bad idea. I actually did that on my K5. I cut a shape like this [ and bent it in like a flap.
I will check it out.
I really believe that between the fan not coming in soon enough and the fan being too far into the shroud, you have 2 things impeding cooling because of airflow.
And I was told that your sausage fingers won't be able to bolt up a fan which is on a low profile fan clutch and has spacers too! Cut that fan shroud!!!
You are too meticulous to do a poor chop job.
