Cooling the 6.0 with an Aluminess Bumper

[Ford_6L_E350]

The van computer also uses throttle position to set the fan speed. Pulling up that grade probably used more throttle and more fan.

Running down the road, my fan doesn't come on until 215 and isn't full on until 225. With plenty of throttle it can come on as low as 195.

So are we worrying about this heat thing too much?

225 plus the 14max delta means EOT 239 before the fan comes on full.

Obviously Ford thought that was acceptable??? Seems hot to me but maybe the oil doesn't care.

I'm switching to T6 at the next oil change thinking about all is heat.

For sure a working degass cap is essential as well. FWT temps at 230 with a failing cap would spell BOIL OVER.

I still want to take more controll of the fan!

Thoughts on the cutting the ground wire?

Can I just T into the wire like you do with a trailer wire harness and add a switch and wire to ground.

Would be awesome if it worked.

Switching to synthetic oil would mean the oil temp is not a concern, only the delta could be an issue.

The real question is do you want to do something about the Aluminess bumper restricting airflow, or just live with it? Somebody on the forum added an air scoop under the Aluminess bumper to get more air into the lower part of the radiator. I was unable to find a picture of it. My memory says it was a successful addition. Or you could put holes through the bumper to allow more airflow. Or go back to a stock bumper.

A simpler way to force more air through the grill, even with an aftermarket bumper, is to add an airdam below the bumper. This creates lower air pressure below the van and will draw more air through the engine compartment.

This will also help with fuel economy. (measurable? maybe not.... but it will help). Just look at the new Superduties for inspiration. I can be semi-flexible to rocks, etc.

But then again.... it may be a lot of worry over nothing. If its not overheating while climbing, than those temps on the flats are probably not an issue.

It was "Zeta" who did the lower scoop, along with hood exhaust vents. I think he also relocated trans cooler and feeds it (I think split into two trans coolers) with ducting off the aux light openings. It is mentioned earlier in this thread. All seem good ideas and in direction of "the right fix" (assuming of course all other components working correctly)

The Aluminess bumper seems a major prob for an already air flow starved compartment since it cuts off a large factory opening to lower half a of radiator (to make no mention of what one might imagine its effect on aerodynamics / flow to the grill opening might be...I haven't looked close yet at where the bug pattern is). Some day I may try the scoop and hood vents.
To my thinking it seems the effectiveness of the fan to drop temps, once on, indicates the poor air flow.

Jody / DP Tuner does tell me that you can modify the programming of the fan...though I think he said it cannot be programmed to come on below 45 mph.

He also mentioned the billet style grill can impede air flow.

I've read the 6.0s are even more sensitive to oil condition...so is the concern with OT greater...or can additives / anti shear be compromised for the 6.0 at a lower max OT than say a 7.3 or any std gasser? We never worried about OT as high as 300 in some of the race cars Ive run, but the 6.0 seems a finicky type.

I think more than one person has done this maybe even Zeta?

I also plan to add louvers in the hood which should help.

So I think the problem is solved. I will know for sure next Friday when I tow 9000lbs back into Colorado. That said I believe the heat issue has been solved through tuning.

I had a 80hp street tune done by DP. Mike from 5 Star built me a 65hp tow tune focusing on heat.

Fan is coming on at 195 FWT now.
Doesn't make sense to me but my delta is 3-5 degrees closer.

It might cost me a bit on mileage with the fan on earlier, I let everyone know.

Anyway, I'll have all the data by next Saturday but on the frontside it seems simple tuning and energizing that 10,000cfm fan may be my solution.

More soon...
