Engine heat management

[Ford_6L_E350]

Eric,

Thanks for the idea of the larger trans cooler. Just got mine today. Looks like a good weekend project.

I have seen 225 trans temp when crawling uphill in lo range. The water temp were kept down by the fan, but the trans cooler couldn't keep up. The larger cooler will certainly help.

That was the impetus to get all this work done that I had been planning on for a while now. (hydroboost brakes, louvers, coolers, transmission filter, fluid changes, and various other small stuff)

I took a look at an F350 yesterday, the vents are significantly smaller. I think the photo I have up is a bit deceptive due to the angle. The vents I put in are about 16" long, and 6" tall at the high point. Here's another photo, though it also is not square on...

Recently did a little experiment on my 2007 E350 6.0 PSD. Instead of adding a new thread I'll post my findings here as this seems to be chasing the same issue.

My van has 42,xxx miles. The deltas are 10 and under, which I believe is within Ford's spec. Past weekend I did the new body style front clip swap for two reasons

• I think it looks more aggressive

• I thought it will also help with the heat dissipation better with a larger grill and relatively larger under hood area because the grill sticks out more with the new style grill header.

Here's my observation of 2 hours drive (90% HWY 10% City)

• The average temps of EOT and ECT dropped by about 5F, for same driving conditions

• The EOT/ECT deltas are down to average of 5 (3 being min and 7 was the max). Measured on hwy after reaching operating temp.

There's another factor that may be contributing to this, that is I did not have the bumper on. But that could only contribute to the avg overall drop in temp but not the delta.

Just my $0.5 on this issue.
